anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 - 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E2 (PGE2) suppression ability on IFN-γ/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl
为寻找有效的抗炎药,设计,合成了二十四个查尔酮衍生物,包括七个新的含吡咯部分的化合物(13-17、21和23),并对其一氧化氮(NO)和前列腺素E2(PGE2)进行了评估。对IFN-γ/ LPS诱导的RAW 264.7巨噬细胞的抑制能力。结果表明,合成的化合物均不是与PAINS相关的分子,具有3-(2,5-二甲氧基苯基)-1-(1H-吡咯-2-基)-丙-2-烯-1-酮(化合物16)对PGE2和NO的生成表现出显着的抑制活性,IC50值分别为0.5±1.5 µM和12.1±1.5 µM。物理化学和ADMET研究表明,大多数化合物都遵循Lipinski的五种规则(RO5),具有高血脑屏障(BBB)渗透,人体肠道吸收(HIA),P-糖蛋白(PgP)抑制和血浆结合蛋白(PPB)抑制。然后将获得的单晶XRD为16的原子坐标应用于分子对接模拟,发现化合物16在ERK和mPGES-1的结合位点参与了许多
