Sobre IBD

Deux dérivés de benzoxazines (3a et 3b) interagissent avec des cibles biologiques pour étudier leurs effets antioxydants et anticancéreux. La substitution par un atome d’hydrogène a permis au composé 3a d’inhiber les radicaux DPPH plus efficacement que l’acide ascorbique, une valeur d’EC50 inférieure. Les investigations in silico ont montré que les composés se liaient spontanément à la glutathion peroxydase 7 via des liaisons hydrogène conventionnelles, suggérant qu’ils pourraient neutraliser les espèces réactives de l’oxygène. Le composé 3a pourrait induire une conformation d’ADN monocaténaire in vitro. Des énergies de liaison similaires aux résultats in vitro ont suggéré des mécanismes d’interaction spécifiques et mineurs dans les expériences de docking. Une augmentation de l’absorbance à 280 nm et une fixation électrostatique des composés à la BSA suggèrent leur potentiel. Ces résultats apportent un éclairage sur les processus pharmacologiques et le potentiel médicinal des dérivés de benzoxazines.
