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.

human A1 adenosine receptor containing a new purine scaffold. To study the structure activity relationships of this new chemical series for adenosine receptors, a library of 24 purines was synthesized and tested in radioligand binding assays at human A1, A2A, A2B and A3 adenosine receptor subtypes. Fourteen molecules showed potent antagonism at A1, A3 or dual A1/A3 adenosine receptors. This purine scaffold
