is the most frequently diagnosed cancer and is one of the leading causes of male cancer death in the world. Recently, in the course of our screening for a novel anticancer compound, we synthesized carbocyclic analogs of pyrrolo[2,3-d]pyrimidine nucleoside; compounds 5, and 6. In the current study, we report the effects of compound 5 on pleiotropic induction of cell death via up-regulation of AR-associated
前列腺癌是最常被诊断的癌症,并且是世界上男性癌症死亡的主要原因之一。最近,在筛选新型抗癌化合物的过程中,我们合成了吡咯并[2,3- d ]嘧啶核苷的碳环类似物;化合物5和6。在当前的研究中,我们报道了化合物5通过上调AR相关的p21 Cip1蛋白在具有不同雄激素反应性的前列腺癌细胞(如LNCaP(雄激素依赖性和敏感性))中对多效性诱导的细胞死亡的影响, LNCaP C4-2(非雄激素依赖性和敏感性;雄激素难治性)和DU145(非雄激素依赖性和敏感性)细胞。 用6μM化合物5处理LNCaP细胞24小时可刺激雄激素受体(AR)活性并显着上调p21 Cip1的转录(56倍),进而诱导细胞中典型的凋亡。但是,通过用化合物5进行密集的细胞处理(9μM,48小时),可以通过在LNCaP C4-2细胞中实现AR相关的p21 Cip1的上调(23倍)诱导凋亡,这是因为细胞的敏感性较低并且比LNCaP细胞更
