article reports the synthesis of new triarylpyrazole derivatives possessing urea or amide linker, and their biological activities at molecular, cellular, and in vivo levels. Compound 2b was the most potent inhibitor of p38α/MAPK14 kinase (IC50 = 22 nM) among this series. Molecular docking studies were conducted to understand the kinase inhibitory variations and the basis of selectivity. Compound 2b was able
本文报道了具有尿素或酰胺连接基的新的三芳基吡唑衍生物的合成及其在分子,细胞和体内水平的生物活性。在该系列中,化合物2b是p38α/ MAPK14激酶最有效的抑制剂(IC50 = 22 nM)。进行了分子对接研究以了解激酶抑制变异和选择性的基础。在nanoBRET细胞激酶试验中,化合物2b能够抑制HEK293细胞内的p38α/ MAPK14激酶,EC50值为0.55μM,与达沙替尼的效价相当。化合物2b抑制脂多糖诱导的THP-1细胞中TNF-α的产生,IC50值为58 nM。另外,化合物2b显示出针对hERG的低效力。它对hERG的效力比E-4031低622.38倍,因此该化合物具有心脏毒性的风险非常小。化合物2b在人和大鼠血浆中在体外也显示出高血浆稳定性。化合物2b的体内PK曲线是可以接受的,并且其抗炎作用与双氯芬酸相当,对胃没有致溃疡的副作用。
