both compounds, deduced from the metal-specific Zinquin assay and ZnL2+ stability constant values in solution, strongly supports their cytotoxicity. These data along with quantum mechanical studies have enabled to establish a precise structure-activity relationship. Moreover, L1a and L5a showed appropriate drug-likeness by in silico methods. Based on these promising results, L1a and L5a should be considered
针对人类癌
细胞系代表小组的体外生存力分析表明,
多胺L1a和L5a表现出显着的活性,其IC50值在微摩尔范围内。初步研究表明,这两种化合物均能促进G1细胞周期阻滞,进而促进细胞衰老和凋亡。凋亡细胞的诱导涉及线粒体外膜通透性的丧失和胱天
蛋白酶3/7的激活。有趣的是,L1a和L5a无法激活细胞DNA损伤反应。从
金属特异性Zinquin测定法和溶液中Zn
L2 +稳定常数值推论得出,这两种化合物的高细胞内
锌螯合能力均强烈支持其细胞毒性。这些数据以及量子力学研究已经能够建立精确的结构-活性关系。此外,L1a和L5a通过计算机方法显示出适当的药物相似性。基于这些有希望的结果,L1a和L5a应该被认为是一类值得进一步发展的新型
锌螯合抗癌剂。
