摘要: 目的 以固相合成法合成抗真菌四肽D-Phe-Val-D-Val-Tyr-OH。 方法 采用固相合成法通过4步反应顺利获得目标四肽,所得化合物的结构通过MS、1H NMR等光谱确证。 结果 合成得到了抗真菌四肽D-Phe-Val-D-Val-Tyr-OH,总收率为47.0%。 结论 合成方法具有可行性,操作简便、总收率高,目标化合物可用于抗真菌药物研究。Abstract: Objective To synthesize the antifungal tetrapetide by solid-phase synthesis method. Methods The solid-phase peptide synthesis was chosen for getting the desired target tetrapeptide and its structure was confirmed by MS and 1H NMR. Results The synthesis of the D-Phe-Val-D-Val-Tyr-OH was realized with yield of 47%. Conclusion The synthetic method was feasible and practical. The desired target tetrapeptide could be used for screening of antifungal activity.
