  • Title: Oxadiazole mannich bases: synthesis and antimycobacterial activity.
    Author: Ali MA, Shaharyar M.
    Journal: Bioorg Med Chem Lett; 2007 Jun 15; 17(12):3314-6. PubMed ID: 17467984.
    Abstract:
    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 M. tuberculosis H(37)Rv 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(37)Rv and isoniazid (INH) resistant M. tuberculosis with Minimum inhibitory concentration (MIC) 0.1 microM & 1.10 microM respectively.
