melodorinol analogues were synthesized via a diverted total synthesis approach, leading to structural modifications on several regions of the molecule. Their cytotoxicity was evaluated against five human cancer cell lines (KB, HeLa-S3, MCF-7, HT-29 and A549). Structure-activity relationship studies revealed key parameters that affect the cytotoxicity. In particular, the novel 4-bromo-furanone analogues exhibited
通过合成了一系列的melodorinol类似物一种转移的全合成方法,导致分子几个区域的结构修饰。评估了它们对五种人类癌细胞系(KB,HeLa-S3,MCF-7,HT-29和A549)的细胞毒性。结构-活性关系研究揭示了影响细胞毒性的关键参数。特别地,与相应的非溴代类似物相比,新型4-溴呋喃酮类似物表现出更大的细胞毒性。C-6的立体化学以及C-6和C-7羟基上的酰基取代基的性质也起着重要的作用。最有效的类似物显示出对KB和HeLa-S3的细胞毒性比美洛瑞诺高约15倍,并且对MCF-7,HT-29和A549细胞系也显示出极高的效能。
