    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.

    Microsponges as Drug Delivery System: Past, Present, and Future Perspectives
    (Bentham Science Publishers, 2023-04-04T00:00:00) Biharee, Avadh; Bhartiya, Sudha; Yadav, Arpita; Thareja, Suresh; Jain, Akhlesh Kumar
    Microsponges are polymeric delivery devices composed of porous microspheres that range in size from 5 to 300 micrometers. These have been explored for biomedical applications such as targeted drug deliv-ery, transdermal drug delivery, anticancer drug delivery, and bone substitutes. The purpose of this study is to conduct a comprehensive analysis of recent developments and prospects for a microsponge-based drug delivery system. The current study analyzes how the Microsponge Delivery System (MDS) is made, how it works, and how it can be used for a wide range of therapeutic purposes. The therapeutic potential and patent information of microsponge-based formulations were systematically analyzed. The authors summarize various effective tech-niques for developing microsponges, such as liquid-liquid suspension polymerization, quasi-emulsion solvent diffusion method, water-in-oil-in-water (w/o/w) emulsion solvent diffusion, oil-in-oil emulsion solvent diffu-sion, lyophilization method, porogen addition method, vibrating orifice aerosol generator method, electro-hydrodynamic atomization method, and ultrasound-assisted microsponge. Microsponge may reduce the side effects and increase drug stability by positively altering drug release. Drugs that are both hydrophilic and hy-drophobic can be loaded into a microsponge and delivered to a specific target. The microsponge delivery technology offers numerous advantages over conventional delivery systems. Microsponges, which are spherical sponge-like nanoparticles with porous surfaces, have the potential to increase the stability of medications. They also efficiently decrease the undesirable effects and alter drug release. � 2023 Bentham Science Publishers.
