Based on the significant and diverse pharmacophore features of triazole ring and considering the potent antimicrobial properties of quinoline scaffold, a novel series of 1,2,3-triazole-based polyaromatic compounds containing chloroquinoline moiety were synthesized through a well-established synthetic methodology, named click chemistry. The structure of the synthetic compounds was characterized by various spectroscopic methods. The final products of triazole/quinoline hybrids and ((prop-2-yn-1-yloxy)methyl)benzene intermediates were screened for their antibacterial (Staphylococcus aureus, Escherichia coli, Shigella flexneri, and Salmonella enterica), antifungal (Candida albicans, Saccharomyces cerevisiae, and Aspergillus fumigatus), and cytotoxic activities. The best antifungal compounds exhibited minimum inhibitory concentration (MIC), in the range of 0.35-0.63 µM, against S. cerevisiae without any cytotoxic effect. These compounds can be selected as the potential candidates for treating invasive fungal infections caused by S. cerevisiae, after further investigation. Preliminary in silico ADME studies also predicted the favorable pharmacokinetic attributes of most compounds.

New benzimidazole-1,2,3-triazole-quinoline hybrids and their intermediates, differing in substitutions at the C-2 and/or C6 positions of the benzimidazole ring, were successfully synthesized in 55---80 % yields, with the C6-substituted ones forming as inseparable tautomeric mixtures. The synthesized compounds were fully characterised by FT-IR, 1D- and 2D-NMR, and HRMS. In-depth NMR analysis and DFT molecular calculations showed that the tautomeric mixtures formed in a ratio of almost 1:1 ratio (cis and trans), except for 5 g, where the ratio is 1:2.

Bacterial infections, caused predominately by Gram-positive and Gram-negative organisms, are proliferation of harmful strains of bacteria on or inside the body. Hospital-acquired and community-acquired bacterial infections have already put a heavy burden on the global health system. Antibiotics can disrupt the processes necessary for bacterial cell growth and proliferation, are effective weapons to fight against bacterial infections.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder worldwide. Currently, the only strategy for palliative treatment of AD is to inhibit acetylcholinesterase (AChE) in order to increase the concentration of acetylcholine in the synaptic cleft. Evidence indicates that AChE also interacts with the β-amyloid (Aβ) protein, acting as a chaperone and increasing the number and neurotoxicity of Aβ fibrils.

Malaria is one of the most prevalent parasitic diseases in the world. The global importance of this disease, current vector control limitations, and the absence of an effective vaccine make the use of therapeutic antimalarial drugs the main strategy to control malaria. Chloroquine is a cost-effective antimalarial drug with a relatively robust safety profile, or therapeutic index.
