Research and development for novel substances possessing anti-infective activity have attracted considerable attention due to the escalating resistance towards conventional antibiotics. Therefore, the discovery and development of effective antimicrobial drugs with novel mechanism of action have become an insistent task for infectious diseases research programs. Triazole scaffold has been consistently rewarded as a promising versatile lead molecule with a pivotal position in modern medicinal chemistry. The literature reveals that this heterocyclic moiety has drawn attention of the chemists, pharmacologists, microbiologists and other researchers owing to its indomitable biological potential as anti-infective agents. The present communication is a cogent attempt to review the chemistry and antimicrobial activities of triazole derivatives reported in recent scientific literature. The biological profiles of these new triazole derivatives represent a fruitful matrix for further development as promising and superior anti-infective medicinal agents.

Emergence of severe viral infections in recent years and limited availability of antiviral chemotherapeutic agents for prevention and treatment of these infections are among the most common causes of human illness and death. Therefore, there is an urgent need to develop antiviral drugs that have a potentially critical role in the prevention and treatment of various fatal and debilitating viral infections. Triazole derivatives occupy a pivotal position in modern medicinal chemistry and several have found applications as medicines. A large volume of research has been carried out on triazole and their derivatives for antiviral activity and pharmacological importance of this scaffold has been well established. This review is primarily addressed to description of the recent advances in the synthesis and evaluation of triazole derivatives as antiviral agents which may facilitate the development of more potent and effective antiviral agents.
