small molecular anticancer agent currently in multiple Phase II clinical trials. Based on the pharmacophore of ONC201, a series of small molecular compounds with a core structure of tetrahydropyrido[4,3-d]pyrimidine-2,4-dione were designed and synthesized. Preliminary mechanism studies of these compounds indicated that they can inhibit the phosphorylation of AKT and ERK, induce the dephosphorylation
ONC201是一种小分子抗癌药,目前正在多项II期临床试验中。基于ONC201的药效团,设计合成了一系列具有四氢
吡啶并[4,3-d]
嘧啶-2,4-二酮核心结构的
小分子化合物。这些化合物的初步机理研究表明,它们可以抑制PC-3细胞中AKT和ERK的
磷酸化,诱导Foxo3a的去
磷酸化,并促进
TRAIL的表达和激活转录因子4(
ATF4)的表达。结构-活性关系(
SAR)研究表明,核心结构上取代基的修饰可以显着改善这些化合物的细胞活性。
