The structure of the newly synthesized 2-(thiazol-4-yl)thiazolidin-4-one derivatives were characterized by the spectroscopic analysis. The synthesized compounds were screened for antimycobacterial activity against Mycobacterium tuberculosis H37Ra (MTB) (ATCC 25177) and Mycobacterium bovis BCG (BCG, ATCC 35743). Most of the 2-(thiazol-4-yl)thiazolidin-4-one derivatives showed good to excellent antimycobacterial activity against both the Mtb strains. Nine derivatives 5c, 5g, 5j, 5m, 5n, 5o, 5p, 5s, and 5t showed excellent activity against M. bovis BCG with MIC 4.43 to 24.04 mu M were further evaluated for the cytotoxicity activity against HeLa A549, and HCT-116 cell lines and showed no significant cytotoxic activity at the maximum concentration evaluated. The potential antimycobacterial activities enforced that the thiazolyl-thiazolidin-4-one derivatives could lead to compounds that could treat tuberculosis.10aCytotoxicity10aMycobacterium tuberculosis10aThiazole10aThiazolidin-4-one1 aAbhale, Yogita, K.1 aShinde, Abhijit1 aShelke, Monika1 aNawale, Laxman1 aSarkar, Dhiman1 aMhaske, Pravin, C.  uhttps://library.ncl.res.in/content/synthesis-new-2-thiazol-4-ylthiazolidin-4-one-derivatives-potential-anti-mycobacterial
