investigation clearly indicated that compounds 3, 11, 12, and 18 induce apoptosis evidenced by chromatin condensation, phosphatidylserine externalization, and caspase-3 activation effects on HeLa cells. The potent capacity to induce apoptosis with concomitant cell loss in G2/M highlights the potential of 27-benzyl analogue (18) as an apoptotic inducer drug candidate.
凋亡诱导剂是发现和开发抗癌剂的一种有吸引力的方法。在此,我们通过的分子微调睡茄素的63种化合物(基于A-文库发展报告2 - 64),它们中的53报道首次。他们对HeLa,A-549和MCF-7人肿瘤细胞系的抗增殖评估确定了十五种类似物,它们的活性(IC 50值范围为0.3–4.8μM)比铅(IC 50)高。值处于滞后或对数生长期的数值(1.3-10.1μM)。SAR分析表明,酰化作用增强了细胞毒性,表明疏水性部分可能通过增加亲和力和/或细胞膜通透性而有助于细胞活性。进一步调查清楚地表明,化合物3,11,12,和18诱导染色质缩合,磷脂酰丝氨酸外翻,并且在HeLa细胞胱天蛋白酶-3激活的细胞凋亡效果证明。在G2 / M中诱导细胞凋亡并伴随细胞丢失的有效能力凸显了27-苄基类似物(18)作为凋亡诱导药物候选物的潜力。
