Through a cell-based biological screening, the benzocinnolinone derivative (±)-2c was identified as a promising STAT3 inhibitor. Since SAR studies on a series of compounds structurally related to (±)-2c (1c, 2a–p, 3c, 4c, 6) showed that the latter had the most significant inhibitory activity, we investigated in depth its essential structural features. In particular, enantiomeric separation was performed
通过基于细胞的生物筛选,所述benzocinnolinone衍生物(±) - 2C被鉴定为有希望的STAT3抑制剂。由于SAR研究了一系列与(±)-2c(1c,2a–p,3c,4c,6)相关的化合物,表明后者具有最显着的抑制活性,因此我们深入研究了其基本结构特征。特别地,进行对映体分离,并且通过理论和晶体学研究确定立体异构体的绝对构型。生物学评估强调,(S)-(-)- 2c的效力是(R)-(+)- 2c。
