The synthesis, in vitro evaluation, and conformational study of His-Phe-Arg-Trp-NH2 and related derivatives acting as antifungal agents are reported. Among them, His-Phe-Arg-Trp-NH2 and His-Tyr-Arg-Trp-NH2 exhibited antifungal activity against Cryptococcus neoformans. Antifungal activity of these compounds appears to be closely related to the alpha-MSH effect. A conformational and electronic study
报道了His-Phe-Arg-Trp-NH2及其相关衍生物作为抗真菌剂的合成,体外评价和构象研究。其中,His-Phe-Arg-Trp-NH2和His-Tyr-Arg-Trp-NH2表现出对新型隐球菌的抗真菌活性。这些化合物的抗真菌活性似乎与α-MSH效应密切相关。构象和电子研究使我们能够为用作抗真菌剂的四肽提出生物学相关的构象。此外,这些理论计算使我们能够确定产生抗真菌反应的最低结构要求,并可以为具有这种生物活性的化合物的设计提供指导。
