Herein we report the synthesis, SAR, and biological evaluation of a series of 1H-pyrrolo[2,3-b]pyridine-2-carboxamide derivatives as selective and potent PDE4B inhibitors. Compound 11h is a PDE4B preferring inhibitor and exhibited acceptable in vitro ADME and significantly inhibited TNF-α release from macrophages exposed to pro-inflammatory stimuli (i.e., lipopolysaccharide and the synthetic bacterial
在此,我们报告了一系列 1 H-吡咯并[2,3 - b ]吡啶-2-甲酰胺衍生物作为选择性和有效的 PDE4B 抑制剂的合成、SAR 和生物学评价。化合物11h是 PDE4B 首选抑制剂,表现出可接受的体外ADME,并显着抑制了巨噬细胞暴露于促炎刺激物(即脂多糖和合成细菌脂肽 Pam3Cys)的 TNF-α 释放。此外,11h对一组 CNS 受体具有选择性,并且代表了在 CNS 疾病环境中进一步优化和临床前测试的极好先导。
