developing potent anti-proliferative agents toward TNBC MDA-MB-231 cell line. In particular, compounds 5e and 10g were the most active hybrids against MDA-MB-231 cells (IC50 = 12.35 ± 0.12 and 12.00 ± 0.13 μM), with 2.37- and 2.44-fold increased activity than 5-fluorouracil (5-FU) (IC50 = 29.38 ± 1.24 μM). Compounds 5e and 10g induced the intrinsic apoptotic mitochondrial pathway in MDA-MB-231; evidenced
由于缺乏明确的分子靶标以及此类疾病的异质性,三阴性乳腺癌(TNBC)患者的治疗具有挑战性。在开发有效的基于伊斯兰蛋白的抗增殖剂的过程中,我们使用了杂交药效团方法来合成三个系列的新型基于伊斯兰蛋白的杂种5a-h,10a-h和13a-c,其主要目标是开发有效的对TNBC MDA-MB-231细胞系的抗增殖剂。特别是,化合物5e和10g是针对MDA-MB-231细胞最具活性的杂种(IC50 = 12.35±0.12和12.00±0.13μM),其活性是5-氟尿嘧啶(5-FU)的2.37和2.44倍(IC50 = 29.38±1.24μM)。化合物5e和10g在MDA-MB-231中诱导内在的凋亡线粒体途径。抗凋亡蛋白Bcl-2的表达降低,促凋亡蛋白Bax的表达增强以及活性caspase-9和caspase-3水平上调证明了这一点。此外,10g的膜联蛋白V-FITC阳性凋亡细胞百分比显着增加,从3
