(S)-2-amino-8-oxodecanoic acid. The isolation and structure elucidation of new apicidins from two Fusarium species, temperature-dependent NMR studies of apicidin, NMR and molecular modeling based conformation of the 12-membered macrocyclic ring, and selected chemical modifications of apicidin have been detailed in this paper. The cyclic nature of the peptide, the C-8 keto group, and the tryptophan are all critical
阿皮啶是一类环状四肽,不包含经典的亲电性α-酮环氧化物,但是组蛋白脱乙酰基酶和抗原生动物剂的有效(nM)抑制剂。这些化合物对原生动物的apicomplexan家族表现出广谱活性,包括疟原虫sp(疟原虫),弓形虫,隐孢子虫和艾美球虫。这些环肽含有一个β-转角氨基酸(R)-Pip或(R)-Pro,(S)-N-甲氧基Trp,(S)-Ile或(S)-Val和(S)-Val 2-氨基-8-氧代十二烷酸或改性的(S)-2-氨基-8-氧代十二烷酸。从两个镰刀菌属物种中分离出新的芹菜素,并对其结构进行了阐明,研究了温度依赖性的芹菜素的NMR研究,NMR和基于分子模型的12元大环结构,并详细介绍了阿匹匹定的化学修饰形式。肽,C-8酮基和色氨酸的环状性质对于生物活性都是至关重要的。
