Tetrazoles derivatives are an important class of compounds, which can be used in the fields of bioorganic and medicinal chemistry as antibacterials, anti-cancer, heart disease, neurodegenerative disease, and antifungal activity (Smissman et al,1976;McGuire et al, 1990;Lunn et al, 1992;Itoh et al, 1995;Upadhayaya et al, 2004;Wu et al, 2008;Rostom et al, 2009. The tetrazole moiety has long been established as a bioisostere of a carboxyl unit (Burger, 1991). A major advantage of tetrazoles over carboxylic acids is that they are resistant to many biological metabolic degradation pathways (Singh et al, 1980).…”

Heterocyclic compounds have been an interesting area for the study of synthesis and biological activity of novel oxadiazole derivatives for a long time. Heterocyclic compounds possess diverse biological properties that have led to intense study and research of these compounds. One of these compounds 1,3,4-Oxadiazole is a versatile heterocyclic nucleus is a novel molecule which attract the medicinal chemist to search a new therapeutic molecule. 1,3,4-oxadizole exhibited a wide range of biological activities which includes antimicrobial activity, anti-tubercular, anticonvulsant, antidiabetic, anti-allergic, enzyme inhibitors, anti-HIV activity, antipyretic activity, Immunosuppressive activity, Spasmolytic Activity, antioxidant activity, Anti-Alzheimer's activity cardiovascular acivity, anti-inflammatory, anti-tumor activity, insecticidal activity, CGRP receptor antagonists, anti-anthelmintic activities. Results of various derivatives of different oxadiazole and their substitutions with diverse biological activities are reviewed in present article.

“…Therefore, in continuation of our ongoing interest in the synthesis novel heterocycles with chemotherapeutic activities [21][22][23][24][25][26][27][28][29][30] , it was considered of interest to prepare some new tetrahydro-and hexahydroindazole derivatives, bearing functionalities that are reported to contribute to potential chemotherapeutic activities such as the sulfonamide, sulfonylurea and thiourea groups. Besides incorporating an electron withdrawing group at position-3 we have also introduced a methyl substituent in position-7.…”
