screening hits 6 and 7 that result in the development of P2Y14R antagonists with a novel 2-phenyl-benzoxazole acetamide chemical scaffold. Notably, compound 52 showed potent P2Y14R antagonistic activity (IC50 = 2 nM), and a stronger inhibitory effect on MSU-induced inflammatory in vitro, better than a previously described P2Y14R antagonist PPTN. In vivo evaluation demonstrated that compound 52 also had
P2Y 14核苷酸受体是 P2Y 受体的一种亚型,与许多人类炎症性疾病有关。基于对几乎对称的 P2Y 14结合域中两个筛选命中的有利残基的鉴定,我们描述了先前确定的虚拟筛选命中6和7的结构优化,导致开发具有新型 2-苯基的 P2Y 14 R 拮抗剂-苯并恶唑乙酰胺化学支架。值得注意的是,化合物52显示出有效的 P2Y 14 R 拮抗活性 (IC 50 = 2 nM),并且在体外 对 MSU 诱导的炎症具有更强的抑制作用,优于先前描述的 P2Y 14 R 拮抗剂 PPTN。体内评估表明,化合物52对小鼠痛风发作的炎症反应也具有令人满意的抑制活性。此外,P2Y 14 R 拮抗剂52通过 cAMP/NLRP3/GSDMD 信号通路减少 MSU 诱导的急性痛风性关节炎小鼠的爪肿胀和炎症细胞浸润。对采用 MM/GBSA 自由能计算/分解的结合机制的讨论也为化合物52的进一步结构设计提供了一些有用
