1,4-Benzoquinone antimicrobial agents against Staphylococcus aureus and Mycobacterium tuberculosis derived from scorpion venom

Abstract

Development of new drugs from the venom of dangerous animals (spiders, snakes, scorpions, snails) has recently attracted much chemotherapeutic interest. While most isolated and characterized venom components are found to be proteinic or peptidic in nature, here we report two 1,4-benzoquinone compounds, one red and another blue, derived from the venom of a rarely studied scorpion ( Diplocentrus melici ) indigenous to Mexico. After successful identification and synthesis of these compounds, the red and blue benzoquinones showed remarkable antimicrobial activities against Staphylococcus aureus and Mycobacterium tuberculosis , respectively. The observation that the blue compound is equally effective against normal and multidrug-resistant tuberculosis while appearing not to affect the epithelium of lungs heightens its potential as a new drug candidate.
