Abstract

[1,2,4]Benzotriazine fused to pyrazole ring is a privileged heterocyclic scaffold present in numerous pharmacologically active compounds. Till date, various pyrazolo[5,1-c][1,2,4]benzotriazine 5-oxides and their deoxy analogues, possessing a broad spectrum of potent pharmacological activities, have been reported. In this review, we highlighted synthesis, chemical reactions, medicinal chemistry aspects and applications of fused pyrazole derivatives of [1,2,4]benzotriazine analogues reported so far.
