Interações da trancinolona com ciclodextrinas em sistemas multicomponentes

Triamcinolone is a relevant anti-inflammatory costicosteroid drug, used mainly by injectable suspensions due its poor water solubility. The association of triamcinolone with cyclodextrins and co-solvents (triethanolamine TEA and N-methylpirrolidone NMP) was held to solubilize the drug and explain the involved interactions. Phase-solubility diagrams showed that triamcinolone was solubilized forming incredible stable complexes with cyclodextrins, in which bests results were observed applying randomyl-methylated-beta-cyclodextrin (RMβCD) (161 fold on increased solubility). The co-solvents TEA and NMP also enhanced drug solubility 1.4 and 6.7 fold, respectively. The association of both co-solvents with CDs seems decreased complexation stability, but enables higher amount of uncomplexed drug. Experimental magnetic resonance 2D-ROESY and theoretical molecular modeling studies demonstrated TRI-CDs interactions and elucidated the structure of formed complex, which occurred due to the inclusion of ring A of TRI on CDs cavity. Physicochemical aspects of solid binary and ternary complexes prepared by spray drying were assessed by using FTIR, X-ray diffraction and SEM photographs. Dissolution studies showed that binary and ternary associations presented higher dissolution efficacy in detrimental to pure drug system. In addition, the ternary complex containing TEA and RMβCD allowed drug dissolution faster than binary complex with RMβCD. Therefore, given the higher solubility and drug dissolution rate, binary and ternary complexes are new raw materials with great potential for pharmaceuticals containing triamcinolone.

Avaliação do efeito do extrato hidroalcoólico das folhas de Anacardium occidentale L. em ratos submetidos à colite ulcerativa

Ulcerative colitis is a chronic disease characterized by inflammation in the intestinal mucosa, in most cases affects the colon and rectum. The therapeutic drugs are used as aminosalicylates and glucocorticosteroids, but due to the low response and the various side effects caused by them, reveals the need to search for new sources of useful compounds in the treatment of this disease.The species Anacardium occidentale popularly known as cashew, has been used for centuries in folk medicine in the healing aid of skin and mucosa lesions.Recent studies show its expressive antiulcerogenic effect, what we instigated to assess the effect of the extract of A. occidentaleleaves in rats with acute ulcerative colitis, therefore, 42 rats were used male Wistar, divided into 06 groups, and Negative Control (C) Positive Control (C +), treated with Sulfasalazine (Sz500) and treated with Extract A. occidentale at doses of 50 (Ao50), 100 (Ao100) and 200 mg / kg (Ao200).All groups were submitted to experimental colitis Ulcerative except C-, moreover, C- and C + received saline via gavage for 7 consecutive days while the other groups received their respective treatments.Euthanasia of animals took place on the 8th day in which it was collected intestinal colon sample for later analysis macroscopic, histopathological, morphometric and biochemistry, as well as complementary collection of blood and liver tissue. The extract is rich in saponins and phenolic compounds such as flavonoids (quercetin and kaempferol) and tannins.When the Sz500 groups and 100 showed significant protection to damage to lipids and proteins, among the groups subjected to experimental ulcerative colitis, the animals Ao100 group obtained the lowest score in all parameters analyzed.Treatment with 100 mg / kg of A. occidentale extract seems to have a combination of antiinflammatory, antioxidant, bactericidal and anabolic promoted by the bioactive compounds present in the extract.However, it is necessary to investigate harder treating dose of 100mg / kg to higher doses compared to elucidate more properly the best therapeutic dosage ulcerative colitis.

Um dermatam sulfato antitrombótico do camarão Litopenaeus vanammei inibe a inflamação e angiogênese

Inflammation is combined of a vascular and a cellular reaction, resulting in different cells and tissue responses, both the intravascular and extravascular environment. As the inflammatory process occurs, coagulation proteases, in particular thrombin (FIIa), are able to initiate various cellular responses in vascular biology and therefore is often observed activation of other biological systems, leading to complications during an event inflammatory, such as thrombosis and angiogenesis. Thus, antagonists molecules of these events are interesting models for the development of novel anti-inflammatory drugs. Thereby, it is worth stressing the glycosaminoglycans (GAGs), which are able to interact with several proteins involved in important biological processes, including inflammation and coagulation. Therefore, this study aimed to evaluate the anti-inflammatory, antithrombotic and anti-angiogenic potentials, as well anticoagulant of a dermatan sulfate-like GAG (DS) extracted from the Litopenaeus vannamei cephalotorax. The compound was obtained after proteolysis and purification by ion-exchange chromatography. After total digestion by DS-like compounds digesting lyases (chondroitinase ABC), the DS-like nature was revealed, and then called DSL. The shrimp compound showed reduced anticoagulant effect by the aPTT assay, but high anti-IIa activity, directly and through heparin cofactor II. On inflammation, the compound had a significant inhibitory effect with the reduction of proinflammatory cytokines. Potential Inhibitory were reported in the antithrombotic and anti-angiogenic assay, the latter being dose dependent. As for anti-hemostatic activity, the polysaccharides did not induced significant bleeding effect. Thus, the results shown by the shrimp DS-like compound indicate this glycosaminoglycan as a biotechnology target with prospects for the development of new multipotent drugs.

Estudo fitoquímico e biológico das folhas de Banisteriopsis argyrophylla (A. Juss.) B. Gates (Malpighiaceae)

With the increasing fungi resistance compared with existing drugs on the market and the side effects reported by some compounds with antioxidant properties and enzymatic inhibitors, in particular against α-amylase and α-glucosidase, the discovery of new compounds with biological potential, becomes a need. In this context, natural products can be an important source for the discovery of new active molecular architectures. Then, this study aimed to evaluate the antioxidant activity, the enzymatic inhibitory activity of α-amylase and α-glucosidase, the antifungal and cytotoxic activities of ethanolic extract (EE) the leaves of Banisteriopsis argyrophylla (Malpighiaceae) and their fractions, obtained by liquid-liquid extraction using solvents of increasing polarity. The antioxidant activity was evaluated by the free radical DPPH scavenging method (2,2-diphenyl-1-picrylhydrazyl) and the ethyl acetate fractions (FAE) and n-butanol (FB) were the most active, confirmed by the peak current and the oxidation potential obtained by differential pulse voltammetry (DPV). The inhibitory activity of the α-amylase and α-glucosidase was analyzed considering the reactions between substrates α-(2-chloro-4-nitrophenyl)-β-1,4-galactopiranosilmaltoside (Gal-α-G2-CNP) and 4-nitrophenyl-α-D-glucopyranoside (p-NPG), respectively. Initially, it was found that the EE showed considerable activity against α-amylase (EC50 = 2.89±0.1 μg m L–1) compared to the acarbose used as positive control (EC50 = 0.08±0.1 μg mL–1) and that did not showed promising activity against the α-glucosidase. After this observation we evaluated the inhibitory activity of α-amylase fractions, with FAE (EC50 = 2.33±0.1 μg mL–1) and FB (EC50 = 2.57 ± 0.1 μg mL–1) showing the best inhibitions. The antifungal activity was evaluated against Candida species, and the FAE had better antifungal potential (MIC's between 93.75 and 11.72 μg mL–1) compared with amphotericin as positive standard (MIC = 1.00 and 2.00 μg L–1 for C. parapsilosis and C. krusei used as controls, respectively). The EE (CC50 = 360.00 ± 12 μg mL–1) and fractions (CC50's> 270.00 μg mL–1) were considerably less toxic to Vero cells than the cisplatin used as positive control (CC50 = 7.01 ± 0 6 μg mL–1). The FAE showed the best results for the activities studied, this fraction was submitted to ultra performance liquid chromatography coupled with mass spectrometry (UPLC-MS)), and the following flavonoids have been identified: (±)-catechin, quercetin-3-O-β-D-Glc/ quercetin-3-O-β-D-Gal, quercetin-3-O-β-L-Ara, quercetin-3-O-β-D-Xyl, quercetin-3-O-α-L-Rha, kaempferol-3-O-α-L-Rha, quercetin-3-O-(2''-galoil)-α-L-Rha, quercetin-3-O-(3''-galoil)-α-L-Rha and kaempferol-3-O-(3''-galoil)-α-L-Rha,. FAE was submitted to column chromatography using C18 phase, and (±)-catechin was isolated (FAE-A1, 73 mg) and three fractions consisting of a mixture of flavonoids were obtained (FAE-A2, FAE-A3 and FAE-A4). These compounds were identified by thin layer chromatography (TLC) and (–)-ESI-MS. The (±)-catechin fraction showed an MIC = 2.83 μg ml–1 in assay using C. glabrata, with amphotericin as positive control. The fractions FAE-A2, FAE-A3, FAE-A4, showed less antifungal potential in tested concentrations. The identified flavonoids are described in the literature, regarding their antioxidant capacity and (±)-catechin, quercetin-3-O-Rha and kaempferol-3-O-Rha are described as α-amylase inhibitors. Thus, B. argyrophylla is an important species that produces compounds with antioxidant potential that can be related to the traditional use as anti-inflammatory and also has antifungal compounds and inhibitors of α-amylase. Therefore, these leaves are promising resources for the production of new drugs.

DISPERSÕES AQUOSAS DE POLIURETANO COMO MATERIAL BASE PARA O DESENVOLVIMENTO DE SISTEMAS DE LIBERTAÇÃO CONTROLADA DE CETOPROFENO

O cetoprofeno (ácido 2-(3-benzoilfenil) propiónico) é um anti-inflamatório não esteroidal (AINE) utilizado no tratamento de uma grande variedade de doenças inflamatórias agudas e crónicas incluindo a artrite reumatoide, osteoartrite e espondilite anquilosante. A sua administração oral prolongada está associada a diversas reações gastrointestinais, tais como irritações e ulcerações. Neste contexto, é importante desenvolver sistemas alternati-vos, nomeadamente sistemas de libertação controlada para administração oral, transdér-mica ou intradérmica. Este trabalho tem como objetivo testar a possibilidade de utilização de dispersões aquosas de poliuretano (PUDs) como material de suporte para a produção de sistemas de liberta-ção controlada de cetoprofeno. Numa primeira etapa, foram sintetizadas PUDs de base poliéster (policaprolactona, PCL) e poliéter (polipropileno-glicol, PPG) utilizando o méto-do de pré-polímero modificado. As dispersões obtidas foram caracterizadas em termos de pH, viscosidade, teor de sólidos e tamanho de partícula. Numa segunda etapa, foi testada a incorporação do cetoprofeno nas PDUs produzidas utilizando duas estratégias para incre-mentar a sua solubilidade em água: (i) utilização de um co-solvente (acetona, DMSO e HYD) e (ii) utilização de um surfactante não iónico (Tween 80). A incorporação foi testada para teores de 5% e 10% (razão fármaco/polímero, m/m). Os filmes produzidos pelo méto-do da evaporação do solvente foram avaliados quanto à sua homogeneidade e caracteriza-dos por FTIR e DSC. Numa terceira fase realizaram-se estudos de libertação em tampão de fosfato salino (PBS) de pH 7.5 tendo como objetivo avaliar a viabilidade de desenvolvimen-to de diferentes tipologias de dispositivos dependendo de um compromisso entre as pro-priedades dos filmes e o comportamento de libertação. Os resultados obtidos podem ajudar na seleção do material de base mais adequado para um determinado fim. Adicionalmente, e mais importante, comprovou-se a viabilidade de utilizar PUDs como material base para o desenvolvimento de sistemas de libertação con-trolada, utilizando como exemplo o cetoprofeno. A avaliação da toxicidade e da atividade anti-inflamatória dos filmes produzidos foi considerada estando em curso neste momento no grupo do Professor Armando Cunha Júnior.

Cirurgia de catarata secundária em criança

Introdução: A catarata em idade pediátrica constitui um desafio cirúrgico. Este desafio assume maior dimensão quando a catarata pediátrica é secundária ao tratamento com radioterapia por tumor ocular. A complexidade da técnica, a maior fragilidade ou fibrose de estruturas oculares e o maior risco de complicações intra e pós operatórias são obstáculos que o cirurgião deve equacionar. Os autores apresentam um caso clinico de uma cirurgia de catarata unilateral, secundária a radiação por feixe de protões externo para tratamento de melanoma da íris, em criança com 11 anos de idade. Métodos: Criança de 8 anos, com lesão pigmentada infero-temporal no olho esquerdo. Estabeleceu-se o diagnóstico de melanoma da íris, tendo realizado radioterapia com feixe acelerado de protões com excisão e recolocação de células limbares. Após 18 meses de radioterapia, constatou-se desenvolvimento de catarata subcapsular posterior com evolução para catarata branca. Aos 11 anos, foi submetida, sob anestesia geral, a facoemulsificação microincisional. Realizaram-se 2 paracenteses de 1 mm e, através destas, efectuou-se a capsulorexis anterior, após coloração com azul tripano. Procedeu-se à realização da incisão principal (2,2mm), à faco-aspiração do cristalino opacificado e à irrigação/aspiração bimanual do córtex. Implantou-se a lente intra-ocular monobloco monofocal (SN 60WF) no saco capsular e efectuou-se capsulorexis posterior primária. Com o objectivo de excluir a presença de vítreo na câmara anterior e simultaneamente obter um efeito anti-inflamatório, injectou-se intra-camerularmente triamcinolona sem conservantes. Resultados: Não se observaram complicações intra ou pós-operatórias, imediatas ou tardias, de relevo. Com 1 ano de evolução, a acuidade visual do olho esquerdo é de 10/10. Após 4 anos de radioterapia não se observa recorrência do tumor, doença metastática nem complicações da radioterapia. Conclusões: A micro-incisão, a capsulorexis posterior primária e a aplicação de triamcinolona intracamerular asseguram maior segurança no procedimento, mais rápida recuperação visual com transparência duradoura do eixo visual e menor inflamação no pós-operatório.

Estudo de ß-glucanas extraídas dos fungos Geastrum saccatum e Polyporos dermoporus: características químicas e atividades biológicas

Fungal polysaccharides have received a great deal of attention due to itsbecause of their potential use in a wide rangegreat variety fromof industries. Some studies have demonstrated that polysaccharides extracted offrom basidiomycetes they have presented significant properties as anti-inflammatory, antimicrobial, antioxidant and anti-tumoral properties. In spite of thisDespite these potential properties, these mushrooms have not been insufficiently investigated, and the great number of antibiotics number produced forby these organisms suggests that they canmay be a new source of bioactives composites source. In tThe present work, reports onlated the chemical composition, potential antioxidant, antiinflammatory and citotoxycity of extracted polymers extracted offrom the fruits bodies of the fungiius Geastrum saccatum and Polyporus dermoporus, native mushrooms of the Atlantic forest inof the state of the Rio Grande do Norte, Brazil. The Cchemical analyses had revealed ademonstrated text of total sugar rates of 65% and 49%, and proteins of 7.0% for in extracts of G. saccatum and P. dermoporus extracts, respectively. The analyses ofNMR spectroscopy of RMN had demonstrated that these extracts are composites forof a complex involving β- glucans and- proteins complex. The inhibition of the formation of superoxide radicals formation was of 88.4% in G. saccatum and 83.3% in P. dermoporus, and 75 and 100% for inhibition of hydroxyls radicals inhibition. TopicalThe topic application of extracts the 10, 30 and 50 mg/kg extract in BALBc mice with cutaneous inflammation induced byfor croton oil demonstrated to inhibitedion of ear edema of ear and cells polimorfonuclears cells atin the inflamed siteplace, being this reply more effective in lower concentrations being more effective. The evaluation of the glucans of G. saccatum and P. dermoporus glucans under induced pleurisy for carrageenan-induced pleurisya of showed the antiinflammatory action of these composites., being analyzed tThe frame number in the pleural exudates and thedosage of nitric oxide dosage was also analyzed. The cytotoxic action of these polymers was analyzed throughthrough the mitochondrial function (MTT). The incubation of the glucans with mononuclear cells of the peripheral blood demonstrated that the extracted glucans extracted fromof G. saccatum havepossess a moderate cytotoxic action. These results suggest that these mushrooms possess polymers formed byfor a complex glucana-protein complex, with antiinflammatory and antioxidant actions

Efeito de glucanas do fungo Caripia montagnei em modelo de inflamação intestinal induzida por tnbs em ratos Wistar e em células de carcinoma de cólon humano HT-29

Compounds derived from fungi has been the subject of many studies in order to broaden the knowledge of their bioactive potential. Polysaccharides from Caripia montagnei have been described to possess anti-inflammatory and antioxidant properties. In this study, glucans extracted from Caripia montagnei mushroom were chemically characterized and their effects evaluated at different doses and intervals of treatment. It was also described their action on colonic injury in the model of colitis induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS), and its action on cells of the human colon carcinoma (HT-29). Compounds extracted of C. montagnei contain high level of carbohydrates (96%), low content of phenolic compounds (1.5%) and low contamination with proteins (2.5%). The (FT-IR) and (NMR) analysis showed that polysaccharides from this species of mushroom are composed of α- and β-glucans. The colonic damage was evaluated by macroscopic, histological, biochemical and immunologic analyses. The results showed a reduction of colonic lesions in all groups treated with the glucans of Caripia montagnei (GCM). GCM significantly reduced the levels of IL-6 (50 and 75 mg/kg, p < 0.05), a major inflammatory cytokine. Biochemical analyses showed that such glucans acted on reducing levels of alkaline phosphatase (75 mg/kg, p < 0.01), nitric oxide (p < 0.001), and myeloperoxidase (p < 0.001). These results were confirmed microscopically by the reduction of cellular infiltration. The increase of catalase activity suggest a protective effect of GCM on colonic tissue, confirming their anti-inflammatory potential. GCM displayed cytostatic activity against HT-29 cells, causing accumulation of cells in G1 phase, blocking the cycle cell progression. Those glucans also showed ability to modulate the adhesion of HT-29 cells to Matrigel® and reduced the oxidative stress. The antiproliferative activity against HT-29 cells displayed by GCM (p <0.001) can be attributed to its cytostatic activity and induction of apoptosis by GCM

Clonagem e expressão do gene que codifica o inibidor de quimotripsina de Erythrina velutina WILLD. - caracterização e avaliação de seu potencial farmacológico

Proteinases are enzymes distributed widely founded in several organisms and perform many different functions, from maintaining homeostasis to the worsening of some diseases such as cancer, autoimmune diseases and infections. The proteins responsible of controlling the action of these enzymes are the inhibitors, that are classified based on their target proteases and are founded since simple organisms, such as bacteria, to higher organisms, such as larger plants and mammals. Plant proteinase inhibitors act by reducing or inactivating the activity of target proteases, thus, these proteins have been studied as potential tools in the treatment of diseases related to protease activities. In this context, an inhibitor of chymotrypsin from Erythrina velutina, called EvCI was previously purified and it was observed that this protein plays in vitro anticoagulant activity and anti-inflammatory activity in in vivo model. Aiming to reduce the environmental impact caused by the purification EvCI in high amounts and to facilitate the process of obtaining this protein, the recombinant chymotrypsin inhibitor from Eryhrina velutina was produced after cloning and expression in Escherichia coli. The bacteria were grown in LB medium and after induction of the expression this material was subjected to procedures for cell lysis and the product was applied on Nickel-affinity column. The proteins adsorbed were digested by thrombin and applied on Chymotrypsin-Sepharose affinity column, obtaining the purified inhibitor, named recEvCI. After electrophoresis, the recombinant inhibitor showed an approximately molecular mass of 17 kDa, and reduced the chymotrypsin and elastase activities in vitro. The recombinant inhibitor was sequenced and was found similar amino acids residues when compared to other inhibitors deposited in the database, with some modifications. recEvCI showed high stability under pH variations and reducing conditions, maintaining its activity around 80%. This protein increased the blood coagulation time in vitro by acting on the intrinsic pathway and did not show cytotoxicity against strains of mouse 3T3 fibroblasts and RAW 264.7 macrophages. recEvCI showed microbicide activity related to release of nitric oxide and consequently the activation of macrophages, futhermore having proinflammatory effects assessed by increased release of TNF-α. These results indicate that recEvCI can be biotechnologically used as a new tool in the control of coagulation-related diseases as well as can be an activating agent of the immune system in immunosuppressed individuals

Efeito do Fucoidam de Fucus vesiculosus em um modelo experimental de artrite reumatóide

Rheumatoid arthritis (RA) is systemic auto imune disorder. It is caracterized by chronic inflammation of joints leading to progressive erosion of cartilage and bone. We investigated the effect of the administration of fucoidan, sulfated polysaccharides, from algae Fucus vesiculosus in the acute (6h) in zymosan-induced arthritis (AZy). Wistar rats (180-230 g) were used for all groups experimental. Non-treated animals received just intraarticular injection of 1 mg the zymosan, control group received intraarticular injection of 50 µL the saline, groups received either fucoidan of Fucus vesiculosus (15, 30, 50 or 70 mg/Kg) or parecoxib (1 mg/Kg) 1 hour after injection of zymosan. After 6 h, the articular exudates were collected for evaluation of the cell influx and nitrite (Griess reaction) release. The sinovial membranes and articular cartilages were excised for histopathological analysis and by determination of the glycosaminoglycan (GAG), respectively. ZyA led to increased NO and cell influx into the joints. Therapeutic administration of the fucoidan or parecoxib did significantly inhibited the cell influx and the synovitis, as compared to non-treated rats (p<0,05), though being able to reduced NO release. Representative agarose gel electrophoresis of the GAGs, the content of condroitin-sulphate was observed during the process. These findings suggest that the fucoidan from Fucus vesiculosus has potential anti-inflammatory activity

Como é realizado o diagnóstico e qual é o manejo clínico na Febre do Chikungunya?

A confirmação da febre do Chicungunya (CHKV) é feita através do diagnóstico laboratorial utilizando-se um dos três testes a seguir, a depender da data do início dos sintomas: 1- Isolamento viral, 2- Reação em cadeia de polimerase em tempo real (RT-PCR), 3- Sorologias IgM e IgG. Para o isolamento viral a amostra de sangue deve ser coletada de preferência nos 3 primeiros dias do início dos sintomas e do 1º ao 8º dias para o PCR. Para a pesquisa de anticorpos IgM coletar amostras preferencialmente a partir do 4º dia de início de sintomas (até aproximadamente 2 meses, embora IgM possa persistir por maior tempo). Para pesquisa de anticorpos IgG ou ensaio de anticorpo neutralizante mostrando títulos crescentes, devem ser coletadas duas amostras, separadas por intervalo de 14 dias, sendo a primeira amostra coletada após o 70 dia do início dos sintomas. Além do sangue outras amostras podem ser utilizadas como o liquido cérebro-espinhal, líquido sinovial, ou ainda biópsias de tecidos ou órgãos. Não existe até o momento antiviral específico para o CHKV, sendo o tratamento inteiramente sintomático ou de suporte. Para o tratamento da fase aguda, que dura em média 7 dias, recomenda-se manter o paciente em repouso e aplicar compressas frias nas articulações acometidas. Prescrever dipirona ou paracetamol para controle da febre e dor, ou codeína para os casos refratários. Ingestão de líquidos (oral ou endovenoso, de acordo com a gravidade do quadro) para reposição de perdas por sudorese, vômitos e outras perdas deve ser instituída. Os anti-inflamatórios não esteroides (ibuprofeno, naproxeno, ácido acetilsalicílico) não devem ser utilizados na fase aguda. Ressalte-se que o ácido acetilsalicílico também é contraindicado nessa fase da doença pelo risco de Síndrome de Reye e de sangramento. Os esteroides estão contraindicados na fase aguda, pelo risco do efeito rebote. Pode-se indicar fisioterapia com exercícios leves para os pacientes em recuperação. Já nas fases subaguda (com duração média de 3 meses) ou crônica (duração maior que 3 meses), indica-se anti-inflamatório não hormonal para alívio do componente artrítico. Uso de analgésicos mais potentes como morfina ou uso de corticosteroides podem ser necessários para pacientes com dor intensa que não obtiveram alívio com os anti-inflamatórios não hormonais. Na presença de fatores de risco (gestantes, crianças < 2 anos, idosos, pacientes com comorbidades) está indicado controle clínico diário até desaparecimento da febre. Diante de sinais de gravidade, recomenda-se manejo em leito de internação. A Febre do CHKV é doença de notificação compulsória imediata, devendo ser notificada imediatamente (menos de 24h) por telefone para Gerencia de Epidemiologia GEREPI ou Centro de Informações Estratégicas em Vigilância em Saúde (CIEVS).
