A novel butanehydrazide derivatives of purine-2,6-dione designed using a ligand-based approach were synthesized and their in vitro activity against both PDE4B and PDE7A isoenzymes was assessed. The 7,8-disubstituted purine-2,6-dione derivatives 31, 34, 37, and 40 appeared to be the most potent PDE4/7 inhibitors with IC50 values in the range of that of the reference rolipram and BRL-50481, respectively
合成了一种新的基于配体的方法设计的嘌呤-2,6-二酮丁酰肼衍生物,并评估了它们对PDE4B和PDE7A同工酶的体外活性。7,8-二取代嘌呤-2,6-二酮衍生物31、34、37和40似乎是最有效的PDE4 / 7抑制剂,IC50值分别在参考咯利普兰和BRL-50481范围内。 。此外,对接研究解释了嘌呤-2,6-二酮核的7位上的N-(2,3,4-三羟基亚苄基)丁酰肼取代基对于双重PDE4 / 7抑制特性的重要性。两种cAMP特异性PDE同工酶的抑制作用均会产生强大的抗TNF-α作用。在体内研究中,LPS诱导的内毒素血症大鼠体内的化合物31、34和37使该促炎细胞因子的最大浓度降低了53,
