Abstract

A litter of pups: The synthesis and in vitro evaluation of new Pup-based fluorogenic substrates for Dop, the mycobacterial depupylase, are described. A full-length Pup-amidomethylcoumarin conjugate as well as an amino-terminus-truncated analogue exhibited high sensitivity and specificity towards hydrolysis by Dop. The substrates developed here might find application as high-throughput screening assay reagents for the identification of Dop inhibitors.

摘要

一窝幼崽

描述了新的基于 Pup 的荧光底物的合成和体外评估,用于 Dop,即分枝杆菌脱 pupylase。全长 Pup-氨甲基香豆素缀合物以及氨基末端截断类似物对 Dop 水解表现出高灵敏度和特异性。这里开发的底物可能会作为高通量筛选测定试剂,用于鉴定 Dop 抑制剂。
