Medicinal Chemistry Aspects of Isoxazole Analogues as Anti-tubercular Agents

Tuberculosis (TB) is the major cause of mortality around the world and one of the most common diseases linked to AIDS. Due to the emergence of multi-drug resistance, extensive drug resistance, and total drug resistance strains, TB has become a difficult disease to treat. Isoxazole scaffold shows a wide range of biological activities, including anticancer, antibacterial, anti-tubercular, antiviral, and anti-inflammatory activities etc. Several isoxazole derivatives have been produced and few of them have shown comparable anti-tubercular activity with standard drugs. In this review, we have focused on reported isoxazole derivatives having anti-tubercular activity and summarized their structure-activity relationship.
