conditions, which favor either of two regioisomers. One regioisomer corresponds to a kinetic product (7a–7c) and the other regioisomer corresponds to a thermodynamic product (8a–8c). Among them, the structure of kinetic product 7b was confirmed by measuring single X-ray crystallography. In vitro PGE2 assay studies showed that the kinetic product (7a and 7b; IC50 = 0.69 and 0.55 μM against PGE2) is generally
在我们先前的研究中,发现了一系列新的苯磺酰肼衍生物,它们通过抑制mPGES-1酶来降低RAW 264.7巨噬细胞中LPS诱导的PGE 2水平。最近,发现根据反应条件形成苯基磺酰肼的区域异构体混合物,其有利于两种区域异构体中的任一种。一个区域异构体对应于动力学乘积(7a – 7c),另一个区域异构体对应于热力学乘积(8a – 8c)。其中,通过测量单X射线晶体学证实了动力学产物7b的结构。体外PGE 2分析研究表明,动力学产物(7a和7b ; 通常, 对PGE 2的IC 50 = 0.69和0.55μM )比对热力学乘积(8a和8b; 对PGE 2的IC 50 => 10和0.79μM )更有效。分子对接研究还显示,动力学产物(7a)的MolDock分数(−147.4)比8a(−142.4)高,这与PGE 2分析结果一致。一种新的强苯基磺酰肼(7d ; 针对PGE 2的IC 50 = 0.0
