utilized to optimize 6,6-diaryl substituted dihydropyrone and hydroxylactam to obtain inhibitors of lactate dehydrogenase (LDH) with low nanomolar biochemical and single-digit micromolar cellular potencies. Surprisingly the replacement of a phenyl with a pyridyl moiety in the chemical structure revealed a new binding mode for the inhibitors with subtle conformational change of the LDHA active site.
基于结构的设计用于优化 6,6-二芳基取代的二氢吡喃酮和羟基内酰胺,以获得具有低纳摩尔生化和个位数微摩尔细胞效力的乳酸脱氢酶 (LDH) 抑制剂。令人惊讶的是,在化学结构中用吡啶基部分取代苯基揭示了一种新的抑制剂结合模式,LDHA 活性位点的构象发生了细微的变化。这导致了一种有效的、具有细胞活性的羟内酰胺抑制剂的鉴定,该抑制剂具有适用于小鼠肿瘤异种移植研究的体内药代动力学特征。
