Description：(H-Cys-pNA)2 是一種不穩(wěn)定的多肽分子，是一種二聚體，已被用作氨肽酶活性的底物。(H-Cys-pNA)2 是氨基肽酶的競(jìng)爭(zhēng)性抑制劑，與酶的活性位點(diǎn)結(jié)合，阻止其從氨基酸中切割肽。(H-Cys-pNA)2 已被證明通過與大鼠腦組織中的催產(chǎn)素受體結(jié)合來抑制催產(chǎn)素的釋放。這種分子還抑制體外無性細(xì)胞瘤細(xì)胞的生長(zhǎng)并阻斷細(xì)胞分裂。(H-Cys-pNA)2 易被蛋白水解降解，可通過聚丙烯酰胺凝膠電泳降解，可用于其在聚丙烯酰胺凝膠上的分析。
(H-Cys-pNA) 2 is an unstable peptide molecule, a dimer, and has been used as a substrate for aminopeptidase activity. (H-Cys-pNA) 2 is a competitive inhibitor of aminopeptidase, which binds to the active site of the enzyme to prevent it from cutting peptides from amino acids. (H-Cys pNA) 2 has been shown to inhibit the release of oxytocin by binding to oxytocin receptors in rat brain tissue. This molecule also inhibits the growth of asexual tumor cells in vitro and blocks cell division. (H-Cys-pNA) 2 is easy to be degraded by protein hydrolysis and can be degraded by polyacrylamide gel electrophoresis, which can be used for its analysis on polyacrylamide gel.
