scanning of a potent and readily accessible analogue 23 revealed the effect of each residue on antiproliferative activity, and a small panel of analogues were prepared to explore the SAR of the non-natural amino acid residue (2S,4R)-AMD. Results from the alanine scan were used to design an expanded library of culicinin D analogues, leading to the discovery of cyclohexylalanine analogue 52, which exhibited
Culicinin D(1)是最初从clavisporces clavisporus分离的10个氨基酸的肽醇,对多种癌细胞系均表现出强大的活性。在我们先前探索不寻常的(2S,4S,6R)-AHMOD残基的构效关系(SAR)的基础上,准备了一系列culicinin D的类似物以进一步研究这些肽的SAR。丙氨酸对有效且易于获得的类似物23的扫描揭示了每个残基对抗增殖活性的影响,并准备了一小组类似物以探索非天然氨基酸残基(2S,4R)-AMD的SAR。丙氨酸扫描的结果被用于设计culicinin D类似物的扩展文库,从而发现了环己基丙氨酸类似物52,
