A new series of quinolone-thiazolidinone hybrid molecules 8a-o were prepared. Quinoline compounds were synthesized by Meth-Cohn synthesis and were condensed with 2,3-disubstituted thiazolidinone. These molecules were screened for their anticancer activities against MDA-MB-231 and MCF-7 cell line using MTT assay. Potent compounds were tested for their cytotoxicity on normal HEK 293 cell lines and most potent compound was tested for its cell cycle analysis. Molecular docking and molecular dynamic studies were performed on human N-acetyl transferase (hNAT-1) protein using Schrodinger molecular docking toolkit. Compound 8n emerged as potent with IC50 8.16?μM against MDA-MB-231 cell line followed by 8e with IC50 17.68?μM. Compound 8n arrested cell cycle at G2/M phase and was non-toxic to human normal kidney cell line. The potent compound 8n binds well with human NAT-1 protein with remarkable hydrogen bonding and π–π interactions. Molecular dynamic studies of 8n further confirm the target for these molecules. Target quinolinone-thiazolidinones were found to be new class of compounds targeting hNAT-1 and can serve as new lead compounds in drug discovery.

A novel series of quinoline-based symmetrical and unsymmetrical bis-chalcones was synthesized via a Claisen–Schmidt condensation reaction between 3-formyl-quinoline/quinolone derivatives with acetone or arylidene acetones, respectively, by using KOH/MeOH/H2O as a reaction medium. Twelve of the obtained compounds were evaluated for their in vitro cytotoxic activity against 60 different human cancer cell lines according to the National Cancer Institute protocol. Among the screened compounds, the symmetrical N-butyl bis-quinolinyl-chalcone 14g and the unsymmetrical quinolinyl-bis-chalcone 17o bearing a 7-chloro-substitution on the N-benzylquinoline moiety and 4-hydroxy-3-methoxy substituent on the phenyl ring, respectively, exhibited the highest overall cytotoxicity against the evaluated cell lines with a GI50 range of 0.16–5.45 μM, with HCT-116 (GI50 = 0.16) and HT29 (GI50 = 0.42 μM) (colon cancer) representing best-case scenarios. Notably, several GI50 values for these compounds were lower than those of the reference drugs doxorubicin and 5-FU. Docking studies performed on selected derivatives yielded very good binding energies in the active site of proteins that participate in key carcinogenic pathways.

Quinolin-3-yl-methyl-1,2,3-triazolyl-1,2,4-triazol-3(4H)-ones 8j-v were synthesized by click chemistry as an ultimate tactic where [3 + 2] cycloaddition of azides with terminal alkynes has been evolved. Herein, we are inclined to divulge the implication and prevalence of CuSO4·5H2O and THF/water promoted [3 + 2] cycloaddition reactions. The foremost supremacy of this method are transitory reaction times, facile workup, excellent yields (88–92%) with exorbitant purity and regioselective single product formation both under conventional and microwave method. Docking studies illustrated strong binding interactions with enzyme InhA-D148G (PDB ID: 4DQU) by means of high C-score values. The anti-tubercular and antifungal screening of synthesized compounds proclaimed promising activity. The in vitro and in silico studies imply that these triazoles appended quinolines may acquire the ideal structural prerequisites for auxiliary expansion of novel therapeutic agents.
