Formylpeptidereceptors (FPRs) play an essential role in the regulation of endogenous inflammation and immunity. In the present studies, a large series of pyridazin-3(2H)-one derivatives bearing an arylacetamide chain at position 2 was synthesized and tested for FPRagonist activity. The pyridazin-3(2H)-one ring was confirmed to be an appropriate scaffold to support FPRagonist activity, and its modification
甲酰肽受体 (FPR) 在调节内源性炎症和免疫中起重要作用。在本研究中,合成了大量在 2 位带有芳基乙酰胺链的哒嗪-3(2 H )-one 衍生物并测试了 FPR 激动剂活性。哒嗪-3(2 H )-one 环被证实是支持 FPR 激动剂活性的合适支架,其在 4 和 6 位的修饰导致鉴定出额外的活性激动剂,从而诱导细胞内 Ca 2+在HL-60 细胞转染了 FPR1、FPR2 或 FPR3。七种甲酰肽受体 1 (FPR1) 特异性和几种混合的 FPR1/FPR2 双激动剂被鉴定为低微摩尔 EC 50值。此外,这些激动剂还激活人类中性粒细胞,诱导细胞内 Ca 2+通量和趋化性。最后,分子对接研究表明,最有效的哒嗪-3(2 H )-ones 分别在 FPR1 和 FPR2 配体结合位点与 fMLF 和 WKYMVM 肽的最佳对接姿势重叠。因此,哒嗪酮类化合物代表了用于进一步开发选择性和/或有效 FPR
