  2-Anilinonicotinyl linked 2-aminobenzothiazoles and [1,2,4]triazolo[1,5-b] [1,2,4]benzothiadiazine conjugates as potential mitochondrial apoptotic inducers

  摘要：

  A series of N-(2-anilino-pyridyl) linked 2-amino benzothiazoles (4a-n) and [1,2,4]triazolo [1,5-b]benzothiadiazine conjugates (5a-j) have been designed, synthesized and evaluated for their antiproliferative activity. Some of these compounds (4h-k, 4n, and 5e) have exhibited potent cytotoxicity specifically against human leukemia HL-60 cell lines with IC50 values in the range of 0.08-0.70 mu M. All these compounds were tested for their effects on the cell cycle perturbations and induction of apoptosis. Morphological evidences of apoptosis, including fragmentation of nuclei and inter nucleosomal DNA laddering formation were clearly observed after 24 h exposure to compound 4i. Flow cytometry analysis revealed that compound 4i showed drastic cell cycle perturbations due to concentration dependant increase in the sub-G0 region which comprises of both the apoptotic and debris fraction, thus implying the extent of cell death. These compounds trigger the mitochondrial apoptotic pathway that results in the loss of mitochondrial membrane potential through activation of multiple caspases followed by activation of caspase-3, and finally cleavage of PARP. Further the mechanism of cell death was analysed by fluorescent microscopic analysis and also by scanning electron microscopy. The cytotoxicity of 4i correlated with induction of apoptosis, caspases activation and DNA damage and thus indicating the apoptotic pathway of anticancer effect of these compounds.

  E7010和白藜芦醇作为微管蛋白聚合抑制剂的新型缀合物的设计，合成和抗增殖活性†

  摘要：

  在E7010和白藜芦醇骨架的基础上，设计合成了新型的（E）-N-苯基-3-苯乙烯基吡啶-2-胺共轭物。在GI 50值范围为2.1μM至20μM的四种人类癌细胞系中评估了这些缀合物的抗增殖活性。发现针对人宫颈癌HepG2癌症，两种缀合物RSV-1和RSV-11的GI 50值比白藜芦醇高13倍，而GI 50值比E7010高1-2倍。他们在一组NCI 60人癌细胞系中显示出高效能和选择性。基于GI 50根据分子建模研究中的60种NCI癌细胞系和对接分数，我们选择了RSV-1和RSV-11进行微管蛋白聚合和机理研究。此外，RSV-1和RSV-11化合物通过与秋水仙碱结合位点牢固结合而抑制微管蛋白的组装。通过流式细胞术评估，G2 / M期被阻滞在HepG2细胞中。基于结构的研究，蛋白质印迹和免疫荧光实验表明，RSV-1和RSV-11使HepG2细胞系中的微管解聚，从而导致G2 / M细胞积聚。
