A series of new benzimidazole-thiazolidinedione hybrids has been synthesized and evaluated for their cytotoxic potential against a selected human cancer cell lines of prostate (PC-3 and DU-145), breast (MDA-MB-231), lung (A549) and a normal breast epithelial cells (MCF10A). Among the tested compounds, 11p exhibited promising cytotoxicity with IC₅₀ value of 11.46 ± 1.46 μM on A549 lung cancer cell line and did not show significant toxicity on normal MCF10A cells. Lung cancer cells (A549) have been used to know the mechanism of cell growth inhibition and apoptosis inducing effect with compound 11p. The treatment of A549 cells with 11p showed typical apoptotic morphology like cell shrinkage, chromatin condensation and horseshoe shaped nuclei formation. Flow-cytometry analysis revealed the G2/M phase of cell cycle arrest in a dose dependent manner. Preliminary mechanistic studies suggested that the cell migration was inhibited through the disruption of F-actin protein. Acridine orange-ethidium bromide (AO-EB), DAPI, annexin V-FITC/propidium iodide, rhodamine-123 and MitoSOX assays suggested the induction of apoptosis in A549 cells by compound 11p.

新型苯并咪唑-噻唑烷二酮杂化物作为潜在的细胞毒性和凋亡诱导剂的合成及生物学评价

已经合成了一系列新的苯并咪唑-噻唑烷二酮杂化物，并评估了它们对选定的人类前列腺癌细胞系（PC-3和DU-145），乳腺（MDA-MB-231），肺（A549）和正常的乳腺上皮细胞（MCF10A）。在测试的化合物中，11p对IC ₅₀表现出有希望的细胞毒性在A549肺癌细胞系上的最大值为11.46±1.46μM，并且对正常的MCF10A细胞没有明显的毒性。肺癌细胞（A549）已被用于了解化合物11p抑制细胞生长和诱导细胞凋亡的机制。用11p处理A549细胞显示出典型的凋亡形态，如细胞收缩，染色质浓缩和马蹄形核形成。流式细胞仪分析显示细胞周期阻滞的G2 / M期呈剂量依赖性。初步的机理研究表明，细胞迁移受到F-肌动蛋白蛋白破坏的抑制。cr啶橙-溴化乙锭（AO-EB），DAPI，膜联蛋白V-FITC /碘化丙啶，若丹明123和MitoSOX分析表明，化合物11p可诱导A549细胞凋亡。
