Novos derivados do sistema heterocíclico 1H-pirazolo[3,4-b]piridina: síntese e assinalamentos de hidrogênios e carbonos por RMN 1D e 2D

The synthesis and NMR analysis of seven new 4-(aryl)amino-5-carboethoxy-1,3-dimethyl-1H-pyrazolo[3,4- b]pyridines (7-13) are described. The synthetic approach used involved the preparation of intermediates 5-aminopyrazol (4), the enamine derivative (5) and the 4-chloro-1H-pyrazolo[3,4-b]pyridine (6). Compounds (7-13) were obtained by treatment of 6 with the desired aniline. The structures of new heterocyclic compounds and their precursors intermediates were assigned on the basis of spectral analysis including 1D and 2D NMR experiments [¹H; 13C{¹H} and DEPT; ¹H x ¹H - COSY; ¹H x13C - COSY, nJ CH, n = 1, 2 or 3 (HETECOR and COLOC)].

Lignanas de Strychnos guianensis (Aublet) Mart.

The present communication reports the isolation and identification of three lignans from metanolic root extracts of Strychnos guianensis (Aublet) Mart.: olivil (1), cycloolivil (2) and the unknown derivative cycloolivil carbonate (3). From hexane extracts was identified a long chain fatty acid mixture and the triterpene lupeol. The analyses were based on chromatographic and spectroscopy techniques (IR, MS, GC/MS, ¹H-NMR and 13C-NMR, 1D (BB, DEPT 135) and 2D (¹H, ¹ H-COSY, ¹H, 13C-COSY, ¹H, 13C-COSY-LR, HMQC, HMBC and NOESY) and comparison with literature data.

Síntese de aliloxi-orto-iodobenzamida derivada de d-glicose e reação de ciclização radicalar mediada por hidreto de tri-n-butilestanho

Methyl 6-O-allyl-2,3-di-O-benzyl-4-deoxy-4-(2 -iodobenzoylamine)-alpha-D-glucopyranoside was synthesized in nine conventional steps from methyl alpha-D-glucopyranoside. Its Bu3SnH-mediated aryl radical cyclization provided a benzomacrolactam, resulting from 11-endo aryl radical cyclization and the reduced uncyclized product methyl 6-O-allyl-4-benzoylamine-2,3-di-O-benzyl-4-deoxy- alpha-D-glucopyranoside. The structures of the three new products were supported by ¹H and 13C NMR spectroscopy and DEPT, COSY and HMQC experiments.

Antifungal derivatives from Piper mollicomum and P. lhotzkyanum (Piperaceae)

Bioguided fractionation of the extracts from leaves of Piper mollicomum and Piper lhotzkyanum against the fungi Cladosporium cladosporioides and C. sphaerospermum afforded seven bioactive compounds, four being chromenes: methyl 2,2-dimethyl-2H-chromene-6-carboxylate, methyl 8-hydroxy-2,2-dimethyl-2H-chromene-6-carboxylate, 2-methyl-2-[4'-methyl-3'-pentenyl]-2H-1-benzopyran-6-carboxylic acid, 2,2-dimethyl-2H-chromene-6-carboxylic acid, one a dihydrochalcone: 2',6'-dihydroxy-4'-methoxydihydrochalcone, and two flavanones: 7-methoxy-5,4'-dihydroxy-flavanone and 7,4'-dimethoxy-5-hydroxy-flavanone. The structures of the bioactive isolated derivatives were elucidated by interpretation of their NMR data [¹H and 13C (BBD, DEPT 135º)], and mass spectral data as well as by comparison with data described in the literature.

Chemical constituents from Tabernaemontana catharinensis root bark: a brief NMR review of indole alkaloids and in vitro cytotoxicity

This work describes the isolation and structural determination of pharmacological compounds present in the bark of roots of Tabernaemontana catharinensis (Apocynaceae). Among the 27 substances detected 12 were identified as terpenoid-indole alkaloids, 2 steroids and 13 pentacyclic triterpenes. Structures were outlined based on HMQC, COSY, DEPT, 13C, and ¹H NMR data and MS. Spectral data of indole alkaloids were reviewed. An in vitro screening of the extracts and isolated compounds was carried out. Compounds ibogamine (5), 3-oxo-coronaridine (9) and 12-methoxy-4-methylvoachalotine (MMV) demonstrated effective cytotoxicity towards SKBR-3 breast adenocarcinoma and C-8161 human melanoma tumor cell lines.

Síntese de 2-iodobenzamidas e 3-(iodoacetamido)benzamidas ligadas à D-galactose e suas reações de carbociclização radicalar mediadas por hidreto de tri-n-butilestanho

Starting from methyl 6-O-allyl-4-azido-2,3-di-O-benzyl-4-deoxy-α-D-galactopyranoside, four new derivatives containing 2-iodobenzamido and 3-(iodoacetamido)benzamido groups were synthesized. These four compounds were submitted to tri-n-butyltin hydride mediated radical cyclization reactions, resulting in two macrolactams from 11- and 15-endo aryl radical cyclization. The corresponding four hydrogenolysis products were also obtained. The structures of the new compounds were elucidated by ¹H and 13C NMR spectroscopy, DEPT, COSY, HMQC and HMBC experiments.

Composição química e atividade anticolinesterásica de uma fração ativa do extrato de folhas de Citrus limon (L.) Burm

This paper describes the chemical composition and acetylcholinesterase inhibition of an active chromatographic fraction of the EtOAc extract of Citrus limon leaves. The composition of the active fraction presented a mixture of two coumarins, 5,8-dimethoxy-psoralen and 5,7- dimethoxycoumarin, identified by ¹H and ¹³C NMR data analysis, including DEPT, COSY, HMBC and HSQC experiments. It was also demonstrated that this mixture presents qualitative and quantitative AChE inhibition. In vitro studies indicated a CE50 value of 340 µg/mL with 95% of confidence. In vivo studies (10 and 25 mg/kg) revealed inhibition of 30.09 and 30.06% of AChE activity in relation to neostigmine, respectively.

Análise comparativa dos efeitos alelopáticos das substâncias químicas titonina e titonina acetilada

Este trabalho teve por objetivo estabelecer as variações na atividade alelopática da substância química titonina, em função da acetilação de sua molécula. Bioensaios de germinação (25 ºC de temperatura constante e fotoperíodo de 12 horas) e de desenvolvimento da radícula e do hipocótilo (25 ºC de temperatura constante e fotoperíodo de 24 horas) foram desenvolvidos. Como planta receptora, utilizou-se a planta daninha Mimosa pudica (malícia). Análise de espectros RMN ¹H e 13C e técnicas de RMN bidimensionais foram realizadas na molécula acetilada. O processo de acetilação produziu a molécula 3'-acetil-7,4'-dimetoxiflavona, que diferiu da molécula original, identificada como 3'-hidroxi-7,4'-dimetoxiflavona. A estrutura da titonina-Ac foi confirmada pelos espectros de RMN ¹H, 13C, DEPT, COSY e HETCOR. A titonina foi acetilada com anidrido acético em piridina. A análise comparativa da atividade alelopática das duas substâncias revelou que titonina-Ac apresentou maior potencial para inibir tanto a germinação das sementes como o desenvolvimento da radícula e do hipocótilo da planta daninha malícia. A intensidade dos efeitos alelopáticos das duas substâncias esteve positivamente associada à concentração. O conjunto das informações obtidas permite sugerir a possibilidade de se aumentar a atividade alelopática de uma substância química sem comprometer suas peculiaridades biológicas desejáveis à natureza e aos interesses da sociedade.

Potencial alelopático de duas neolignanas isoladas de folhas de Virola surinamensis (Myristicaceae)

Este trabalho teve por objetivos isolar, identificar e caracterizar a atividade alelopática de substâncias químicas presentes nas folhas de Virola surinamensis. O processo de isolamento e identificação das substâncias químicas envolveu o uso de solventes orgânicos e de Ressonância Magnética Nuclear (RMN ¹H, RMN 13C e RMN 13C-DEPT), espectro de COSY e de HETCOR. A avaliação da atividade alelopática foi realizada em bioensaios de germinação de sementes, em condições de 25 ºC de temperatura constante e fotoperíodo de 12 horas, e de desenvolvimento da radícula e do hipocótilo, com 25 ºC de temperatura constante e fotoperíodo de 24 horas, empregando-se concentrações variando de 1,0 a 8,0 mg L-1. Como plantas receptoras, foram utilizadas as espécies daninhas Mimosa pudica, Senna obtusifolia e Senna occidentalis. Foram isoladas e identificadas duas neolignanas: a surinamensina e a virolina. A tendência geral observada nos resultados foi de aumento da intensidade dos efeitos alelopáticos inibitórios em função do aumento da concentração, com inibições máximas obtidas, sempre, na concentração de 8,0 mg L-1. A surinamensina apresentou maior potencial para inibir a germinação e o desenvolvimento da radícula e do hipocótilo do que a virolina, independentemente da espécie receptora e do fator da planta analisado. Considerando-se as intensidades dos efeitos promovidos sobre os três fatores das plantas, o desenvolvimento da radícula e o do hipocótilo foram mais intensamente inibidos pelas duas substâncias do que a germinação das sementes. À exceção dos efeitos verificados sobre o desenvolvimento do hipocótilo, malícia foi a espécie de maior sensibilidade aos efeitos alelopáticos das duas neolignanas, enquanto mata-pasto foi aquela que evidenciou inibições de menor magnitude.

Structural studies in the Southern Province, South of Sudbury, Ontario

Rocks correlated with the Hough Lake and Quirke Lake Groups of the Huronian Supergroup form part of a northeasterly trending corridor that separates 1750 Ma granitic intrusive rocks of the Chief Lake batholith from the 1850 Ma mafic intrusive rocks of the Sudbury Igneous Complex. This corridor is dissected by two major structural features; the Murray Fault Zone (MFZ) and the Long Lake Fault (LLF). Detailed structural mapping and microstructural analysis indicates that the LLF, which has juxtaposed Huronian rocks of different deformation style and metamorphism grade, was a more significant plane of dislocation than the MFZ. The sense of displacement along the LLF is high angle reverse in which rocks to the southeast have been raised relative to those in the northwest. South of the LLF Huronian rocks underwent ductile defonnation at amphibolite facies conditions. The strain was constrictional, defined by a triaxial strain ellipsoid in which X > Y > z. Calculations of a regional k value were approximately 1.3. Penetrative ductile defonnation resulted in the development of a preferred crystallographic orientation in quartz as well as the elongation of quartz grains to fonn a regional southeast-northwest trending, subvertical lineation. Similar lithologies north of the LLF underwent dominantly brittle deformation under greenschist facies conditions. Deformation north of the LLF is characterized by the thrusting of structural blocks to form angular discordances in bedding orientation which were previously interpreted as folds. Ductile deformation occurred between 1750 and 1238 Ma and is correlated with a regional period of south over north reverse faulting that effected much of the southern Sudbury region. Post dating the reverse faulting event was a period of sedimentation as a conglomerate unit was deposited on vertically bedded Huronian rocks. Rocks in the study area were intruded by both mafic and felsic dykes. The 1238 Ma mafic dykes appear to have been offset during a period of dextral strike slip displacement along the major fault'). Indirect evidence indicates that this event occurred after the thrusting at 950 to 1100 Ma associated with the Grenvillian Orogeny.
