Abstract :

In this study, we have carried out Gaussian-based 3D-QSAR model against the target COX-2 with good statistical significance (R2training=0.86) and predictability (Q2training=0.66, Q2test=0.84). The 3D-QSAR includes steric, electrostatic, hydrophobic and hydrogen bond acceptor field indicators, whereas the potential field contributions indicate that the steric and hydrophobic features of the molecules play an important role in governing their biological activity. The anti-cancer activity of the benzo[h]quinolines was evaluated on cultured human skin cancer (G361), lung cancer (H460), breast cancer (MCF7) and colon cancer (HCT116) cell lines. The inhibitory effect of these compounds on the cell growth was determined by the MTT assay. Among the synthesized compounds 3e, 3f, 3h and 3j showed potential cytotoxicity against these human cancer cell lines. Effect of active compounds on DNA oxidation and on expression of apoptosis related gene was studied. While their bioavailability/drug-likeness was predicted to be acceptable but requires future optimization. These findings reveal that benzo[h]quinolines act as anti-cancer agents by inducing oxidative stressmediated DNA damage. Molecular simulation study was performed to find binding conformations and different bonding behaviors, in order to reveal the possible mechanism of action behind higher accumulation of active benzo[h]quinolines with �?�?�?²-tubulin.
