Thiol-Based Potent and Selective HDAC6 Inhibitors Promote Tubulin Acetylation and T-Regulatory Cell Suppressive Function
摘要:
Several new mercaptoacetamides were synthesized and studied as HDAC6 inhibitors. One compound, 2b, bearing an aminoquinoline cap group, was found to show 1.3 nM potency at HDAC6, with >3000-fold selectivity over HDAC1. 2b also showed excellent efficacy at increasing tubulin acetylation in rat primary cortical cultures, inducing a 10-fold increase in acetylated tubulin at 1 mu M. To assess possible therapeutic effects, compounds were assayed for their ability to increase T-regulatory (Treg) suppressive function. Some but not all of the compounds increased Treg function, and thereby decreased conventional T cell activation and proliferation in vitro.

An investigation into the effect of modified β-lysines on the growth rates of eubacterial cells is reported. It is shown that the effects observed are due to the post translational modification of Elongation Factor P (EFP) with these compounds catalysed by PoxA. PoxA was found to be remarkably promiscuous, which allowed the activity of a wide range of exogenous β-lysines to be examined. Two chain-elongated
The oxidativecleavage of alkenes is an integral process that converts feedstock materials into high-value synthetic intermediates1,2,3. The most viable method to achieve this in one chemical step is with ozone4,5,6,7, which however poses technical and safety challenges owing to the explosive nature of ozonolysis products8,9. Herein, we disclose an alternative approach to achieve oxidative cleavage
