Synthesis and in vitro activity of 6-amino-2,9-diarylpurines for Mycobacterium tuberculosis
摘要:
A mild method was developed to synthesize 6-amino-2-phenolic-9-alkyl and 9-arylpurines. The new compounds were screened for antibacterial activity against Mycobacterium tuberculosis strain H(37)Rv. The 9-tolyl derivatives with a dimethylamino or a piperidine substituent in C6 and the 3-hydroxyphenyl or 4-hydroxyphenyl substituent in C2 were highly active against the bacilli.

A simple and general 'one-pot' procedure for the synthesis of 2,9-diarylpurines with one or multiple hydroxyl groups in the 2-aryl unit is described, from the reaction of 5-amino-4-amidinoimidazoles with phenolic aldehydes.
