Structure–activity relationships of 2-aminothiazoles effective against Mycobacterium tuberculosis
摘要:
A series of 2-aminothiazoles was synthesized based on a HTS scaffold from a whole-cell screen against Mycobacterium tuberculosis (Mtb). The SAR shows the central thiazole moiety and the 2-pyridyl moiety at C-4 of the thiazole are intolerant to modification. However, the N-2 position of the aminothiazole exhibits high flexibility and we successfully improved the antitubercular activity of the initial hit by more than 128-fold through introduction of substituted benzoyl groups at this position. N-(3-Chlorobenzoyl)-4-(2-pyridinyl)-1,3-thiazol-2-amine (55) emerged as one of the most promising analogues with a MIC of 0.024 mu M or 0.008 mu g/mL in 7H9 media and therapeutic index of nearly similar to 300. However, 55 is rapidly metabolized by human liver microsomes (t(1/2) = 28 min) with metabolism occurring at the invariant aminothiazole moiety and Mtb develops spontaneous low-level resistance with a frequency of similar to 10 (5).

A series of compounds derived from the 2-amino-4-(2-pyridyl) thiazole scaffold was synthesized and tested for in vitro antimycobacterial activity against the Mycobacterium tuberculosis H37Rv strain, antiplasmodial activity against the chloroquine sensitive NF54 Plasmodium falciparum strain and cytotoxicity on a mammalian cell line. Optimal antimycobacterial activity was found with compounds with a 2-pyridyl ring at position 4 of the thiazole scaffold, a substituted phenyl ring at the 2-amino position, and an amide linker between the scaffold and the substituted phenyl. The antiplasmodial activity was best with compounds that had the phenyl ring substituted with hydrophobic electron withdrawing groups. (C) 2013 Elsevier Ltd. All rights reserved.
