The 1,2,3-triazole ring system can be easily obtained by widely used copper-catalyzed click reaction of azides with alkynes. 1,2,3-triazole exhibits myriad of biological activities, including antibacterial antimalarial, and antiviral activities. We herein reported the synthesis of quinoline-based [1,2,3]-triazole hybrid derivative via Cu(I)-catalyzed click reaction of 4-azido-7-chloroquinoline with alkyne derivative of hydroxybenzotriazole (HOBt). The compound was fully characterized by proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), correlated spectroscopy (1H-1H-COSY), heteronuclear single quantum coherence (HSQC) and distortionless enhancement by polarization transfer (DEPT-135 and DEPT-90) NMR, ultraviolet (UV) and Fourier-transform infrared (FTIR) spectroscopies, and high-resolution mass spectrometry (HRMS). Computational studies were enrolled to predict the interaction of the synthesized compound with acetylcholinesterase, a target of primary relevance for developing new therapeutic options to counteract neurodegeneration. Moreover, the drug-likeness of the compound was also investigated by predicting its pharmacokinetic properties.

We herein reported the synthesis of quinoline-based [1,2,3]-triazole hybrid via Cu(I)-catalyzed click reaction of 4-azido-7-chloroquinoline with alkyne derivative of 2-bromobenzaldehyde. The compound was fully characterized by proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), heteronuclear single quantum coherence (HSQC), ultraviolet (UV), and high-resolution mass spectroscopies (HRMS). This compound was screened in vitro against two different normal cell lines. Preliminary studies attempted to evaluate its interaction with Delta RBD of spike protein of SARS-CoV-2 by bio-layer interferometry. Finally, the drug-likeness of the compound was also investigated by predicting its pharmacokinetic properties.

1,2,3-triazole pharmacophore is a widely recognized motif used for a variety of applications, including drug discovery, chemical biology, and materials science. We herein report the synthesis of a derivative of azidothymidine (AZT), which was combined with the 7-chloro quinoline scaffold through a 1,4-disubstituted 1,2,3-triazole. The chemical structure of the new molecule was fully characterized by Fourier transform infrared (FTIR) spectroscopy, proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), heteronuclear single quantum coherence (HSQC), heteronuclear multiple bond correlation (HMBC) distortionless enhancement by polarization transfer (DEPT), correlation spectroscopy (1H-1H-COSY), ultraviolet (UV) spectroscopy, and high-resolution mass spectrometry (HRMS). Computational studies were used to predict the interaction of the synthesized compound with HIV reverse transcriptase, a target of relevance for developing new therapeutics against AIDS. The drug-likeness of the compound was also investigated by computing the physico-chemical properties that are important for the pharmacokinetic profile.
