    Synthesis, biological evaluation and in-silico ADME studies of novel series of thiazolidin-2,4-dione derivatives as antimicrobial, antioxidant and anticancer agents
    (BioMed Central Ltd, 2022-09-15T00:00:00) Kumar, Harsh; Kumar, Davinder; Kumar, Pradeep; Thareja, Suresh; Marwaha, Minakshi Gupta; Navik, Umashanker; Marwaha, Rakesh Kumar
    Background: A novel series of thiazolidine-2,4-dione molecules was derived and their chemical structures were established using physiochemical parameters and spectral techniques (1H-NMR, IR, MS etc.). The synthesized molecule were then evaluated for their antioxidant, anticancer and antimicrobial potential. Results and discussion: Serial tube dilution method was employed to evaluate the antimicrobial potential against selected fungal and bacterial strains by taking fluconazole and cefadroxil as reference antifungal and antibacterial drugs respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity was used to assess the antioxidant potential of the synthesized analogues. Further, the anticancer potential of the selected molecules was assessed against DU-145 cancer cell lines using MTT assay. The drug-likeness was also evaluated by studying in-silico ADME parameters of the synthesized analogues. Conclusion: In antioxidant evaluation studies, the analogue H5 with IC50 = 14.85�?g/mL was found to be the most active molecule. The antimicrobial evaluation outcomes suggested that the molecules H5, H13, H15 and H18 possessed moderate to promising activity against the selected species of microbial strains having MIC range 7.3��M to 26.3��M. The results of anticancer evaluation revealed that all the screened derivatives possess mild anticancer potential. The in-silico ADME studies revealed that all the compounds were found to be drug-like. � 2022, The Author(s).

    Flavonoids as promising anticancer agents: an in silico investigation of ADMET, binding affinity by molecular docking and molecular dynamics simulations
    (Taylor and Francis Ltd., 2022-09-27T00:00:00) Biharee, Avadh; Yadav, Arpita; Jangid, Kailash; Singh, Yogesh; Kulkarni, Swanand; Sawant, Devesh M.; Kumar, Pradeep; Thareja, Suresh; Jain, Akhlesh Kumar
    Cancer is one of the most concerning diseases to humankind. Various treatment strategies are being employed for its treatment, out of which use of natural products is an essential one. Flavonoids have proven to be promising anticancer targets since decades. Also, tubulin is a significant biological target for the development of anticancer agents due to its crucial role in mitosis and abundance throughout the body. In the current study, in silico ADMET parameters of 104 flavonoids were examined, followed by molecular docking with the colchicine binding site of Tubulin protein (PDB; Id 4O2B). The best conformation from each flavonoid subcategory with the best docking score (MolDock score) was further subjected to 100 ns of molecular dynamics to investigate the protein-ligand complex�s stability. Different parameters such as RMSD, RMSF, rGy and SASA were calculated for the six flavonoids using molecular dynamic studies. The top most compound from all the six subcategories of flavonoids elicited best behavior in the colchicine binding site of Tubulin protein. This in silico study employing molecular docking and molecular dynamics simulation provides strong evidence for flavonoids to be excellent anti-tubulin agents for the treatment of cancer.
