Design,synthesis and antituberculosis activity of 2-aryl substituted benzothiopyranone compounds
A novel series of 2-aryl substituted benzothiopyranone compounds was designed and synthesized based on our previously obtained benzothiopyranone scaffold with significant antituberculosis activity.All target compounds were evaluated for their antimycobacterial activity and preliminary druggability was subsequently investigated for some selected compounds with good activity.The results indicated that most compounds showed good activity against Mycobacterium tuberculosis H37Rv.Among them,compounds 8g,8h,8q and 9f showed potent activity with MIC ranged from 0.2 to 0.4 μg·mL-1.Furthermore,some active compounds exhibited low cytotoxicity and cardiotoxicity risk.It is worth noting that compounds 8h and 8q with good liver microsome stability and low inhibition of CYPs 3A4/5 and 2C9 were suitable for combination drug regimen to treat tuberculosis.
