macrocyclic peptidomimetics are reported, which employ iterative peptide coupling followed by high yielding ring-closing metathesis (RCM) as the key cyclization step. The target macrocyclic compounds include examples containing a (2S)-amino-8-oxodecanoic acid (Aoda) residue as analogues of apicidin A, a known potent histone deacetylase (HDAC) inhibitor. These showed modest levels of biological activity
报道了新颖的16元大环拟肽的合成,其使用迭代肽偶联,然后高产率的闭环复分解(RCM)作为关键环化步骤。目标大环化合物包括含有(2S)-氨基-8-氧代十二烷酸(Aoda)残基作为阿皮定A的类似物的例子,阿皮定A是已知的有效组蛋白脱乙酰基酶(HDAC)抑制剂。这些显示出适度水平的作为HDAC抑制剂的生物活性。
