A series of bis[3,5-bis(benzylidene)-4-oxo-1-piperidinyl]amides 1 display potent cytotoxic properties towards a wide range of tumours. A number of the CC50 and IC50 values are in the range of 10−8 M. Specifically, these compounds have the following important properties. First, greater toxicity was demonstrated towards certain tumours than various non-malignant cells. Second, various compounds in series
一系列双[3,5-双(亚苄基)-4-氧代-1-哌啶基]酰胺1对多种肿瘤均表现出强力的细胞毒性。CC 50和IC 50的值在10 -8 M的范围内。具体地,这些化合物具有以下重要的性质。首先,证明了对某些肿瘤的毒性要大于各种非恶性细胞。第二,系列1中的各种化合物对许多人类结肠癌和白血病细胞有毒性。第三,这些化合物逆转了P-gp介导的多药耐药性。各种原型分子,例如1a,b和1i被鉴定为铅分子有待进一步研究。代表性的铅分子1b通过核内体DNA片段化和PARP裂解在HSC-2和HL-60细胞中诱导凋亡,而流式细胞仪显示该化合物在人结肠癌HCT-116的细胞周期中阻断了G2 / M和S期细胞。
