Synthesis and evaluation of lysine derived sulfamides as histone deacetylase inhibitors

Bioorg Med Chem Lett. 2009 Apr 1;19(7):1866-70. doi: 10.1016/j.bmcl.2009.02.075. Epub 2009 Feb 23.

Abstract

We have recently reported on a novel class of histone deacetylase (HDAC) inhibitors bearing a sulfamide group as the zinc-binding unit. Herein, we report on the synthesis of sulfamide based inhibitors designed around a lysine scaffold and their structure-activity relationships against HDAC1 and HDAC6 isotypes as well as 293T cells. Our efforts led us to an improvement of the originally disclosed lysine-based sulfamide, 2a to compound 12h which has equal potency in enzyme and cell-based assays as well as enhanced metabolic stability and PK profile.
