Synthetic account on indoles and their analogues as potential anti-plasmodial agents.

Malaria caused by P. falciparum, has been recognized as one of the major infectious diseases causing the death of several patients as per the reports from the World Health Organization. In search of effective therapeutic agents against malaria, several research groups have started working on the design and development of novel heterocycles as anti-malarial agents.

Synthesis of some novel pyrazolo[3,4-] pyrimidin-4(5)-one derivatives as potential antimicrobial agent.

Objectives: The aim of the present work was to synthesize a novel series of pyrazolo[3,4-]pyrimidin-4(5)-one derivatives and evaluate their antimicrobial activity.

Methods: Cyclization of an ortho-amino ester of 1-(2,4-dinitrophenyl)pyrazole with various aliphatic/aromatic nitriles under different reaction conditions such as conventional and microwave assisted synthesis, provided pyrazolo[3,4-] pyrimidin-4(5)-one derivatives. All the synthesized compounds were evaluated for their antimicrobial activity against selected bacteria and fungi by agar well diffusion method.
