  of compounds, using structure-based design concepts, coupled with optimization of cellular potency, in vitro drug–target residence times, and in vivo PK properties, to identify first-in-class inhibitors that demonstrate LDH inhibition in vivo. The lead compounds, named NCATS-SM1440 (43) and NCATS-SM1441 (52), possess desirable attributes for further studying the effect of in vivo LDH inhibition.

  乳酸脱氢酶（LDH）催化丙酮酸向乳酸的转化，同时还原的烟酰胺腺嘌呤二核苷酸的氧化是糖酵解途径的最后一步。糖酵解在癌细胞的代谢可塑性中起重要作用，长期以来一直被认为是潜在的治疗靶点。因此，LDH的有效的选择性抑制剂代表了一种有吸引力的治疗方法。然而，迄今为止，药理剂未能实现体内显着的靶标结合，可能是因为蛋白质以非常高的浓度存在于细胞中。我们在此报告了一项领先的优化运动，该研究使用基于结构的设计概念，重点研究了吡唑基系列化合物，并在体外优化了细胞效能药物-靶标的停留时间和体内PK特性，以鉴定可证明LDH在体内具有抑制作用的一流抑制剂。名为NCATS-SM1440（43）和NCATS-SM1441（52）的先导化合物具有进一步研究体内LDH抑制作用所需的属性。
