Application

MeO-SucAAPVpNA已用于测量嗜中性粒细胞弹性蛋白酶活性：
  • 人和小鼠嗜中性粒细胞体外补充锌补充造成的结果
  • 确定老化嗜中性粒细胞的功能特性，以评估它们在促进肿瘤转移方面的作用
  • 确定伯尔硬胡桃（Sclerocarya birrea (A. Rich.)）的抗弹性蛋白酶作用Hochst

Biochem/physiol Actions

人类白细胞弹性蛋白酶 (HLE) 是一种丝氨酸蛋白酶，与炎症和组织退化相关。它是最具破坏性的蛋白酶之一，其在肺气肿进程中的作用得到了广泛研究。这种肽酶可被HLE及不同物种和细胞的其他弹性蛋白酶选择性水解。弹性蛋白酶样蛋白酶切割MeO-SucAPVVpNA对于肿瘤坏死因子-α (TNF-α)和白细胞介素-1α (IL-1α)诱导的血小板活化因子(PAF)合成至关重要。由于释放4-硝基苯胺，底物的酶促水解速率随着吸光度增加。通常在400 nm或更高波长处测量吸光度。

Upon viral recognition, innate and adaptive antiviral immune responses are initiated by genital epithelial cells (ECs) to eradicate or contain viral infection. Such responses, however, are often accompanied by inflammation that contributes to acquisition and progression of sexually transmitted infections

A series of novel low molecular weight thiocarbamate esters (1e-6e) were synthesized and evaluated as inhibitors of human leukocyte elastase (HLE). The thiocarbamate esters studied consist of a substituted primary or secondary aliphatic or aromatic amine and a 1-phenyl-1H-tetrazole-5-thiol (Table
