The present invention provides substituted heterocyclyl derivatives of formula (I), which may be therapeutically useful, more particularly as NAMPT inhibitors; in which R1, R2, X1, X2, ring A, L and 'n' have the meanings given in the specification, and pharmaceutically acceptable salts thereof that are useful in the treatment and prevention of diseases or disorder caused by an elevated level of nicotinamide phosphoribosyltransferase (NAMPT) in a mammal. The present invention also provides preparation of the compounds and pharmaceutical formulations comprising at least one of the substituted fused heterocyclyl derivatives of formula (I) or pharmaceutically acceptable salts or stereoisomers thereof.

urged to find new alternatives to fight this infection. Carbonic Anhydrase from Schistosoma mansoni (SmCA) is a possible new target against this nematode. Here, we propose new PZQ derivatives bearing a primary sulphonamide group in order to obtain hybrid drugs. All compounds were evaluated for their inhibition profiles on both humans and Schistosoma CAs, X-ray crystal data of SmCA and hCA II in adduct
摘要 血吸虫病是一种被忽视的寄生虫病,由血吸虫属的吸虫引起的寄生虫病几乎空无一物,除吡喹酮 (PZQ) 外,人们敦促寻找新的替代品来对抗这种感染。曼氏血吸虫碳酸酐酶(SmCA) 可能是对抗这种线虫的新靶点。在这里,我们提出了带有伯磺酰胺基团的新 PZQ 衍生物,以获得混合药物。评估了所有化合物对人类和血吸虫 CAs 的抑制谱,获得了 SmCA 和 hCA II 与一些抑制剂的加合物的 X 射线晶体数据,从而了解导致活性的主要结构因素。这些化合物在体外显示出对未成熟和成人的抑制作用S. mansoni,但需要进一步优化以提高活性。
