We report the synthesis of antitubercular 8-nitrobenzothiazinones and their antimycobacterial characterization. A synthesis using thiourea intermediates was established, and 35 analogues were prepared. Their antimycobacterial potential was investigated againstMycobacteriumtuberculosis: minimal inhibitory concentrations (MICs) of all derivatives were determined in broth and in a macrophage infection

The invention belongs to the medicine field, and particularly relates to benzothiazinethione derivatives and preparation methods and uses thereof. In the aspect of the present invention, novel benzothiazinethione derivatives of formula I are provided, the benzothiazinethione derivatives of the invention are new compounds obtained based on extensive screening. Experimental results show that the benzothiazinethione derivatives of formula I have obvious inhibitory effects on mycobacterium tuberculosis, with effects equivalent to or even better than that of isoniazide (MIC90=0.8µM). The benzothiazinethione derivatives of formula I have anti-mycobacterium tuberculosis activities, and provide new choices for the development and application of antitubercular agents.
