A new series of quinoline-chalcone hybrids was synthesized. The structures of these compounds were characterized by spectroscopic methods including 1H and 13CNMR and mass spectroscopy. The cytotoxic activity of compounds was evaluated against four human cancer cell lines including A2780 (human ovarian carcinoma) and A2780/RCIS (Cisplatin resistant human ovarian carcinoma), MCF-7 (human breast cancer cells), MCF-7/MX (Mitoxantrone resistant human breast cancer cells) and normal Huvec cells. The structure-activity relationship of synthesized compounds is discussed. Among quinolines 5e, 5g and 5j possessing benzoyl group showed significant cytotoxic activity against both resistant cancer cells and their parents. Compounds 5g and 5j, demonstrated the most antiproliferative activity with IC50 values ranging from 2.32 to 22.4 μM. They were also identified as tubulin inhibitors and induced cell cycle arrest at G2/M phase and apoptosis. Compound 5j induced more arrest at G2/M phase in four cancer cell lines compared to compound 5g. Finally, molecular dynamics simulation and molecular docking studies of compound 5j into the colchicine-binding site of tubulin demonstrated the possible interaction of this compound in the active site of tubulin.

Based on our previous results and literature precedence, a series of 2-anilinopyridinyl-benzothiazole Schiff bases were rationally designed by performing molecular modeling experiments on some selected molecules. The binding energies of the docked molecules were better than the E7010, and the Schiff base with trimethoxy group on benzothiazole moiety, 4y was the best. This was followed by the synthesis of a series of the designed molecules by a convenient synthetic route and evaluation of their anticancer potential. Most of the compounds have shown significant growth inhibition against the tested cell lines and the compound 4y exhibited good antiproliferative activity with a GI50 value of 3.8?μM specifically against the cell line DU145. In agreement with the docking results, 4y exerted cytotoxicity by the disruption of the microtubule dynamics by inhibiting tubulin polymerization via effective binding into colchicine domain, comparable to E7010. Detailed binding modes of 4y with colchicine binding site of tubulin were studied by molecular docking. Furthermore, 4y induced apoptosis as evidenced by biological studies like mitochondrial membrane potential, caspase-3, and Annexin V-FITC assays.

A general methodology malonic ester amide synthesis has been demonstrated, which uses α-substituted/unsubstituted diethyl malonates for the decarboxylative acylation of various aromatic/heteroaromatic primary/secondary amines to form one-carbon homologated amides, thus providing easy access to amides with odd/even chain lengths and an array of substituents on the alkyl/aryl part while avoiding use of acyl chlorides or peptide coupling reagents.
