Gln-Val-Val-Ala-Gly is a sequence which is common in cysteine protease inhibitors. Poly(ethylene glycol) hybrids of Gln-Val-Val-Ala-Gly analogs were prepared by the solid phase method by fluorenylmethyloxycarbonyl chemistry. The hybrid formation of Gln-Val-Val-Ala-Gly resulted in improvement of the solubility and also in enhancement of the inhibitory effect of the peptide on papain. In addition, the hybrid formation of Gln-Val-Val-Ala-Gly analogs resulted in the enhancement of the inhibitory effect of the peptide analogs.
谷氨酰胺-缬氨酸-缬氨酸-丙氨酸-甘氨酸是半胱氨酸蛋白酶抑制剂中常见的序列。通过芴甲氧羰基化学的固相方法制备了谷氨酰胺-缬氨酸-缬氨酸-丙氨酸-甘氨酸类似物的聚乙二醇杂化物。谷氨酰胺-缬氨酸-缬氨酸-丙氨酸-甘氨酸的杂化形成提高了溶解度，同时增强了该肽对木瓜蛋白酶的抑制作用。此外，谷氨酰胺-缬氨酸-缬氨酸-丙氨酸-甘氨酸类似物的杂化形成增强了肽类似物的抑制作用。
