Based on the bioisosteric replacement of the pyrazole C3-carboxamide of rimonabant with a 5-alkyl oxadiazole ring, a novel class of oxadiazole derivatives with promising biological activity towards CB1 receptors was discovered. Among them, compounds with an alkyl linker containing a strong electron-withdrawing group (e.g., CF3) and a sterically favorable bulky group (e.g., t-butyl) exhibited excellent CB1 antagonism and selectivity, and thus might serve as potential candidates for further development as anti-obesity agents.
基于利莫那班的吡唑C3-酰胺的生物等排替换为五元氧二氮杂环,发现了一类新型氧二氮杂环衍生物,具有有希望的生物活性,对CB1受体具有活性。其中,含有强吸电子基团(例如,CF3)和立体有利的大体积基团(例如,叔丁基)的烷基链路的化合物表现出优异的CB1拮抗作用和选择性,因此可能作为进一步开发为抗肥胖药物的潜在候选。
