Synthesis of quercetin derivatives as cytotoxic against breast cancer MCF-7 cell line and studies.

Quercetin being antioxidant and antiproliferative agent acts by inhibiting CDK2, with an increase in cancer prevalence there is a need to profile quercetin derivatives as CDK2 inhibitors. Schiff bases of quercetin were synthesized as cytotoxic agents against the MCF7 cell line. FTIR, H-NMR and C-NMR, CHNS/O analysis were employed along with and activities. 2q, 4q, 8q and 9q derivatives have maximum cytotoxic effect with IC values 39.7 ± 0.7, 36.65 ± 0.25, 35.49 ± 0.21 and 36.99 ± 0.45, respectively. Molecular docking also confirmed these results 8q has the highest binding potential of -9.165 KJ/mole making it a potent inhibitor of CDK2. These derivatives can be used as lead compounds as potent CDK2 inhibitors.
