N2 - A novel series of Mannich derivatives of 3a-g and 3a′-g′ were designed and synthesized from pseudophenylpropanolamine (Ψ-PPA). The stereo chemical aspects of the synthesized compounds were studied and all compounds were well characterized with respect to spectral techniques. All Mannich derivatives, 3a-g and 3a′-g′ were evaluated for their anti-proliferative activity against A549 and HepG-2 cells. Among the tested compounds, 3a showed significant anti-proliferative activity against HepG-2 cells at 25 μM when compared to other compounds. The treatment of 3a exhibited morphological changes, nuclear condensation, colony formatting ability, apoptosis and cell cycle arrest at G2/M phase in HepG-2 cells. Besides, 3a triggered mitochondrial mediated apoptotic pathway as indicated by down regulation of Bcl-2, up-regulation of Bax, and release of cytochrome c and caspases-3. Furthermore, 3a effectively suppressed the cell proliferation and cell growth via JAK2/STAT3 signaling pathway in a time and dose dependent manner. In vivo administration of 3a inhibited tumor growth without significant change in body weight in HepG-2 xenograft mice model. Molecular docking studies revealed that good binding energies of compound 3a against JAK2 (-6.10 kcal mol-1) and Bcl-2 (-6.04 kcal mol-1) receptors. Taken together, 3a possessed potent antitumor activity; it could be a promising lead candidate for the potential treatment of human hepatocellular carcinoma.
