Oxadiazole mannich bases: Synthesis and antimycobacterial activity

A series of oxadiazole mannich bases were synthesized by reacting oxadiazole derivatives, dapsone and appropriate aldehyde in the presence of methanol. The synthesized compounds were evaluated for antimycobacterial activity against Mycobacterium tuberculosis H 37Rv and INH resistant M. tuberculosis....

description A series of oxadiazole mannich bases were synthesized by reacting oxadiazole derivatives, dapsone and appropriate aldehyde in the presence of methanol. The synthesized compounds were evaluated for antimycobacterial activity against Mycobacterium tuberculosis H 37Rv and INH resistant M. tuberculosis. Among the synthesized compounds, compound ( 4) 3-{2-furyl[4-(4-{2-furyl[5-(2-naphthyloxymethyl)-2-thioxo-2,3-dihydro-1,3,4-oxadiazol-3-yl]methylamino}phenylsulfonyl)anilino]methyl}-5-(2-naphthyloxymethyl)-2,3-dihydro-1,3,4-oxadiazole-2-thione was found to be the most promising compound active against M. tuberculosis H 37Rv and isoniazid (INH) resistant M. tuberculosis with minimum inhibitory concentration (MIC) 0.1 μM & 1.10 μM respectively.
