(±)-peharmaline A, a hybrid natural product isolated from seeds of Peganum harmala L. possesses significant cytotoxic activities. Herein, we have described the design, and synthesis of a novel library of close and simplified analogues around the anticancer natural product (±)-peharmaline A and investigated their cytotoxic activities, which led to the identification of three structurally simplified lead compounds
肿瘤块复杂的异质环境通常会导致耐药性并促进化疗不敏感,从而在癌症患者中引发更多的恶性表型。事实证明,主要的 DNA 损伤性癌症药物在提高化疗耐药性方面并不成功。(±)-peharmaline A 是从骆驼蓬种子中分离出来的杂种天然产物,具有显着的细胞毒活性。在此,我们描述了围绕抗癌天然产物 (±)-peharmaline A 的新型紧密和简化类似物库的设计和合成,并研究了它们的细胞毒性活性,从而鉴定了三种结构简化的先导化合物,它们表现出更好的效力比母体天然产物。其中,peharmaline A 的去甲氧基类似物的抗癌潜力被进一步研究,促使去甲氧基类似物作为有效的 DNA 损伤诱导剂,减弱负责 DNA 损伤修复的蛋白质的表达。因此,这种去甲氧基类似物需要进行详细的研究,以确认其抗癌活性的基于分子机制的研究。 __________________________________________
