Six series based on barbituric acid 5a-e, 10a-d; thiobarbituric acid 6a-e, 11a-d and 1,3-dimethylbarbituric acid 7a-e, 12a-d were prepared and screened for their in vitro PARP1 inhibition. They revealed promising inhibition at nanomolar level especially compounds 5c, 7b, 7d and 7e (IC50 = 30.51, 41.60, 41.53 and 36.33 nM) with higher potency than olaparib (IC50 = 43.59 nM). Moreover, compounds 5b,
基于巴比妥酸5a-e,10a-d的六个系列; 制备了硫代巴比妥酸6a-e,11a-d和1,3-二甲基巴比妥酸7a-e,12a-d,并对其体外PARP1抑制作用进行了筛选。他们显示出在纳摩尔水平上有希望的抑制作用,尤其是化合物5c,7b,7d和7e(IC 50 = 30.51、41.60、41.53和36.33 nM),其效力高于奥拉帕尼(IC 50 = 43.59 nM)。此外,化合物5b,5d,7a,12a和12c表现出良好的可比活性(IC 50 分别为65.93、58.90、66.57、45.40和50.62 nM)。此外,在BRCA1突变的三阴性乳腺癌细胞系MDA-MB-436中评估了体外对PARP1活性最高的化合物5c,7b,7d,7e,12a和12c,其中5c和12c与olaparib相比显示出更高的效能,并且结果在细胞周期停滞在G2 / M期。5c和12c在MDA-MB-4
