In the present study, four silver based NHC (N-heterocyclic carbene) complexes (1c-4c) were designed and synthesized from their precursor salts (1b-4b). The successful synthesis of salts and complexes was assured through spectroscopic techniques (UV-visible, FTIR, 1H NMR) as well as mass spectrometry. The in silico ADMET study and molecular docking calculations predicted the compounds are good drug candidates having therapeutic potential against multiple cancer targets including COX-1, VEGFA, HIF as well as VGF. Results of in vitro study conducted through MTT assay confirmed that all test compounds have concentration dependent potency but silver complexes (1c-4c) have far superior activity than precursor, salts (1b-4b) and slightly lower than standard drugs (carboplatin and cisplatin) against various cancer cell lines. Among the studied compounds, 3c showed lowest IC50 value of 0.981± 0.09, 1.10± 0.14 and 0.973± 0.12 µg/mL against MCF-7, HCT-116 and A549 respectively. The test compounds were found good antibacterial agents, when screened against bacterial strains (Staphylococcus aureus, Micrococcus luteus, Escherichia coli and Salmonella typhimurium), as well as antioxidant agents when tested against DPPH free radicals.

Ionic liquids (ILs) are remarkable for biological activities in numerous medical fields. With the aim of enhancing biological potential of azolium based ILs, four new selenium-N-Heterocyclic Carbene (Se-NHC) adducts were synthesized from bis-imidazolium and bis-benzimidazolium molten salts. Synthesized ILs (L1-L4) and Se-NHC adducts (C1 C4) were confirmed through elemental analysis, chromatographic and spectroscopic techniques including UHPLC-PDA, FTIR, 1H NMR & 13C NMR spectroscopy as well as mass spectrometry. The compounds were found stable in solution form for upto 96 h measured spectroscopically and showed partition coefficient with optimum lipophilicity measured through shake flask method. The simulation studies of these compounds for cancerous proteins indicated that there could be good to high anticancer potential due to their high affinity and less binding energies for COX-1, EGF, VEGF-A and HIF cancer protein targets. The In Vitro cytotoxicity study of compounds confirmed that these compounds were found highly active showeing IC50 against HCT-116 (1.074–1.116 µg mL−1), A549 (0.977–1.325 µg mL−1) and MCF-7 (0.869–1.378 µg mL−1) which is almost better than standard drug 5-Flourouracil but slightly lower than cisplatin and oxaliplatin. The interaction study of compounds with albumin proteins (BSA) and hemolysis assay assured their least toxicity.
