Isomers of chiral drugs can exhibit marked differences in biological activities. We studied the binding and inhibitory activities of 12 compounds against KDM5A. Among them are two pairs of enantiomers representing two distinct inhibitor chemotypes, namely, (R)- and (S)-2-((2-chlorophenyl)(2-(piperidin-1-yl)ethoxy)methyl)-1H-pyrrolo[3,2-b]pyridine-7-carboxylic acid (compounds N51 and N52) and (R)- and
手性药物的异构体在生物活性方面表现出显着差异。我们研究了 12 种化合物对 KDM5A 的结合和抑制活性。其中有两对对映异构体代表两种不同的抑制剂化学型,即 ( R )- 和 ( S )-2-((2-氯苯基)(2-(哌啶-1-基)乙氧基)甲基)-1 H -吡咯并[3,2- b ]吡啶-7-甲酸(化合物N51和N52 )和( R ) -和( S ) -N- (1-(3-异丙基-1H-吡唑-5-羰基)吡咯烷-3-基)环丙烷甲酰胺(化合物N54和N55 )。在体外, N51 / N52对的S对映体( N52 )和N54 / N55对的R对映体( N54 )表现出约4至5倍的结合亲和力。对于细胞可渗透的N54 / N55对, R-亚型对KDM5A的更有效的酶抑制转化为生长抑制活性的差异。我们确定了与所有 12 种抑制剂复合的 KDM5A 催化结构域的结构,这揭示了导致结合亲和力差异的相互作用(或缺
