potent angiotensin-convertingenzyme (ACE) inhibitors, 1-(N2-substituted L-lysyl-gamma-D-glutamyl)octahydro-1H-indole-2-carboxylic acids, was synthesized; various acyl groups were introduced at the alpha-amino group of the N-terminal P1 Lys. The effect of the N2-acyl groups on in vitro inhibitory activity and oral antihypertensive effect was examined. All of the synthesized N-acyl tripeptides were found

Human splenin (hSP) was synthesized by assembling eight peptide fragments followed by deprotection with 1 M trifluoromethanesulfonic acid-thioanisole (molar ratios, 1 : 1) in trifluoroacetic acid in the presence of m-cresol and dimethylselenium. Finally, the depretected peptide was insubated with dithiothreitol to reduce sulfoxide on the methionine side chain. Incubation of peripheral lymphocytes isolated from uremic patients with the synthetic hSP showed an enhancing effect on the reduced B-lymphocytes, but had no restoring effect on the impaired blastogenic response of T-lymphocytes.
在间甲酚和二甲基硒的存在下,先将八个肽片段组装起来,然后在三氟乙酸中用 1 M 三氟甲磺酸-硫代苯甲醚(摩尔比为 1:1)进行脱保护,从而合成了人脾蛋白(hSP)。最后,用二硫苏糖醇还原甲硫氨酸侧链上的亚砜。用合成的 hSP 培养从尿毒症患者体内分离出来的外周淋巴细胞,结果表明它对减少的 B 淋巴细胞有增强作用,但对受损的 T 淋巴细胞增殖反应没有恢复作用。
