Highly active, small-molecule furin inhibitors are attractive drug candidates to fend off bacterial exotoxins and viral infection. Based on the 22-residue, active Lys fragment of the mung bean trypsin inhibitor, a series of furin inhibitors were designed and synthesized, and their inhibitory activity toward furin and kexin was evaluated using enzyme kinetic analysis. The most potent inhibitor, containing 16 amino acid residues with a Ki value of 2.45×10~(-9) M for furin and of 5.60×10~(-7) M for kexin, was designed by three incremental approaches.

本论文研究活性多肽类似物的设计、制备和功能，分为四个部分，采用多肽固相和液相合成的方法，分别合成了活性多肽绿豆胰蛋白酶抑制剂Lys片段长链16肽、天花粉胰蛋白酶抑制剂、癌胚抗原肽、甜味肽等一系列类似物，并测定了这些类似物的生物活性，有以下新的研究结果：1、furin酶抑制剂的设计、制备和功能；2、芳香氨基酸芳环之间的π-π共轭能部分补偿二硫键的作用；3、癌胚抗原肽Gly4被L-Pro替代可增加与HLA-A2分子的结合；4、肽键对甜味肽保持甜味是必须的。
