To enable the large-scale synthesis of coibamide A, we developed an improved synthetic strategy for this class of cyclodepsipeptide. The versatility of the synthetic procedure was demonstrated by the preparation of a series of designed coibamide A analogues, which enabled the preliminary structure–activity relationship (SAR) studies for this compound. Although most modifications of coibamide A resulted
为使coibamide A大规模合成,我们为此类环二肽开发了改进的合成策略。合成方法的多功能性由一系列设计的coibamide A类似物的制备证明,这使该化合物的初步结构-活性关系(SAR)研究成为可能。尽管coibamide A的大多数修饰导致抗增殖性降低或丧失,但我们发现在位置3处的多功能取代具有良好的耐受性。值得注意的是,一种简化的类似物[MeAla3-MeAla6] -coibamide(1f),不仅对被测癌细胞显示出与coibamide A几乎相同的抑制作用,而且还明显抑制了体内肿瘤的生长。这项研究中披露的合成策略的改进和SAR的相关趋势将对进一步优化coibamide A的整体概况具有宝贵的价值。
