Description: SQ109 is a drug undergoing development for treatment of tuberculosis. SQ109 showed activity against both drug susceptible and Multi-drug-resistant tuberculosis bacteria, including Extensively drug-resistant tuberculosis strains. In preclinical studies SQ109 enhanced the activity of anti-tubercular drugs isoniazid and rifampin and reduced by >30% the time required to cure mice of experimental TB.
