ABSTRACT: A series of Mannich products bearing quinoline nucleus was synthesized, characterized, and evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H37Rv. The results showed that compounds 4b, and 4d found most active with percentage inhibition of 95, and 96, respectively, at minimum inhibitory concentration (MIC) of >6.25 μg/mL, among the synthesized compounds. Whereas, compounds 4a, 4c, 4e, and 4f exhibited considerable antitubercular activity with percentage inhibition of 71, 79, 55, and 68, respectively, at MIC of >6.25 μg/mL. The structures of synthesized compounds were elucidated by various spectroscopic tools like IR, 1H NMR, 13C NMR, mass and elemental analysis.
