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.

The enzymes MetAP-2 and NMT play a crucial role in the process of myristoylation of oncoproteins which is deregulated in many types of cancers. Execution of both these enzymes is considered as strategy for the intervention of various cancers and relative fungal infections, and hence the discovery of novel MetAP-2 and NMT inhibitors necessitate their high relevancy. In this investigation, we have synthesized a series of novel seven-membered triazolothiadiazepinyl quinolines 10(a–m) distinctively under microwave irradiation technique and identified as selective MetAP-2 and NMT inhibitors. Amongst the functionalized derivatives when evaluated for the in vitro antifungal assay, compounds 10b, 10c, 10e and 10f were considered promising due to notable inhibitory effects (MIC = 0.2 mg/mL) on Aspergillus fumigatus. Screening of the anticancer activity against NCI-60 Human tumor cell lines portrayed that conjugates 10b, 10c, 10e and 10f were found to be moderately effective against the Renal Cancer cell line UO-31. The data acquired from biological studies was further validated by molecular docking studies and pharmacokinetic evaluation.

Synthetic route has been developed for the synthesis of new (Z)-5-[4-(2-chloroquinolin-3-yl) methoxy]benzylidinethiazolidine-2,4-diones (6a-h) starting from 2-chloro-3-hydroxymethyl quinolines (2a-h). The hydroxy methyl quinolines on tosylation yielded (3a-h). Condensation of the tosyl intermediates with 4-hydroxy benzaldehydes has been carried in DMF in presence of K2CO3 and obtained 4-quinolinyl methoxy benzaldehydes (4a-h). Conveniently Knoevenagel condensation of quinolinyl methoxy benzaldehydes (4a-h) and 2, 4-thiazolidinedione (5) has been carried in PEG-400 in presence of L-proline and obtained better yields of the titled compounds (6a-h).
