Synthesis, docking study and biological evaluation of some new thiourea derivatives bearing benzenesulfonamide moiety.

ABSTRACT: BACKGROUND:A series of novel N-(2, 6-dimethoxypyrimidin-4-yl)-4-(3-(aryl)thioureido) benzenesulfonamides 3a-t was synthesized by the addition of N-(2,6-dimethoxypyrimidin-4-yl)-4-isothiocyanatobenzenesulfonamide 2 to the appropriate aromatic amine. The structures of the synthesized compounds were inspired from the second line antituberculosis pro-drugs. RESULTS:Most of the new compounds were screened for their activity against Mycobacterium tuberculosis. The results of the antimycobacterial assay showed that compound 3i exerted the highest activity (MIC = 3.13 µg/mL), followed by compound 3s (MIC = 6.25 µg/mL). CONCLUSION:The structure-activity relationship (SAR) analysis revealed that the introduction of the benzo[1,3]dioxol moiety in 3i and the 4-morpholinyl-4-phenyl moiety in 3s has pro
