Papel del factor de transcripción ETS 1 y 2 sobre la liberación y funcionalidad de las células progenitoras endoteliales en arterias humanas. Modulación por fármacos

La enfermedad cardiovascular sigue siendo la principal causa de morbilidad y mortalidad a nivel mundial en países desarrollados, fundamentalmente en pacientes con DM tipo 2, en algunas poblaciones puede representar el 50% o más de las muertes por diabetes (Joseph and Golden, 2014). Esto se debe en gran medida a factores ya conocidos como la predisposición genética, la aterogénesis acelerada, la inflamación crónica, la isquemia silente y la presencia de patologías co-existentes como la hipertensión o la dislipidemia. La diabetes es sin duda alguna, uno de los problemas de salud más graves del siglo XXI y actualmente en España, la prevalencia nacional es de 10,83% (FDI 2013). Las células progenitoras endoteliales juegan un papel clave en los procesos de reparación endotelial. En los pacientes con DM tipo 2 y enfermedad cardiovascular, se sabe que la funcionalidad de las EPCs es deficiente, aunque el mecanismo exacto de disfunción aún es incierto. Además, está bien descrito que en la evolución natural de los pacientes con DM tipo 2 presentan un mayor número de complicaciones y con mayor frecuencia estos pacientes estarán abocados a procedimientos de revascularización. Múltiples estudios (Sidhu and Boden, 2015; Verma et al., 2013) que han señalado la importancia de una adecuada terapia de reparación endotelial (terapia con EPCs), que ayudaría a disminuir las alteraciones en los procesos de reendotelización en los pacientes con DM tipo 2 y enfermedad cardiovascular, y por consiguiente disminuiría la aparición de la enfermedad cardiovascular (ECV)...

Solvent-Free Enantioselective Friedländer Condensation with Wet 1,1′-Binaphthalene-2,2′-diamine-Derived Prolinamides as Organocatalysts

Wet unsupported and supported 1,1′-binaphthalene-2,2′-diamine (BINAM) derived prolinamides are efficient organocatalysts under solvent-free conditions at room temperature to perform the synthesis of chiral tacrine analogues in good yields (up to 93%) and excellent enantioselectivies (up to 96%). The Friedländer reaction involved in this process takes place with several cyclohexanone derivatives and 2-aminoaromatic aldehydes, and it is compatible with the presence of either electron-withdrawing or electron-donating groups at the aromatic ring of the 2-aminoaryl aldehyde derivatives used as electrophiles. The reaction can be extended to cyclopentanone derivatives, affording a regioisomeric but separable mixture of products. The use of the wet silica gel supported organocatalyst, under solvent-free conditions, for this process led to the expected product (up to 87% enantiomeric excess), with its reuse being possible at least up to five times.
