Plasmodium falciparum causes approximately 1 million deaths annually. However, increasing resistance imposes a continuous threat to existing drug therapies. We previously reported a number of potent and selective triazolopyrimidine-based inhibitors of P.
Synthetic studies directed towards agelasine analogs - Synthesis, tautomerism, and alkylation of 2-substituted N-methoxy-9-methyl-9H-purin-6- amines

N-Methoxy-9-methyl-9H-purin-6-amines, carrying various substituents in the 2 positions, were synthesized by the N-methylation of known 6-chloropurines, followed by a displacement of the chlorine. Great variations in the amino/imino tautomer ratio among the compounds studied were observed. The tautomers were identified by NMR methods. Treatment of N-methoxy-9-methyl-9H-purin-6-amines carrying alkyl, alkoxy, or amino substituents in the 2 position with benzyl bromide resulted in a mixture of N-7- and N6-benzylated compounds with the former as the major products. N-Methoxy-9-methyl-9H-purin-6-amines with strongly electronegative substituents at C-2 hardly reacted at all under the same set of reaction conditions. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

, (2008/06/13)
6-substituted purinyl piperazine derivatives and a method of synthesis for the derivatives are described. The 6-substituted purinyl piperazine derivatives are useful as cardiotonic agents and antiarrhythmic agents.
