【 摘 要 】

To develop novel antimycobacterial agents, a new series of thiazolidinone-azole hybrids 4a-b, 5a-b and 6-13 were designed and synthesized. Thiazolidin-4-ones (4a-b and 5a-b) were obtained by the reaction of Schiff bases and hydrazones (2a-b and 3a-b) with mercaptoacetic acid. 5-Benzylidene derivatives (6-13) were gained by treatment of 5a-b with appropriate benzaldehydes according to Knoevenagel condensation. To evaluate their structures 1H NMR, IR, mass spectrometry and elemental analysis data were used. The target compounds were screened for their antimycobacterial activity against M. tuberculosis H37Rv strain using the microplate alamar blue assay method. Among them, 6, 10 and 12 (MIC: 14.27-14.74 μM) were found as most active compounds in the series. It was seen that both phenylamino and benzylidene substitutions on thiazolidin-4-one ring caused an improvement in the antimycobacterial activity.
