Drug discovery and the process of new drug design have been formulated much easier in the past two decades by introducing, proliferation of combined physical, biochemical process from computing capabilities and computational approaches. Since the breast cancer is one of the life-threatening problems globally, no effective prescription is still now invented or not available in the market or medical treatment. Although the few number of drugs is just touched on the market, the remedy has consisted of severe side effects and low efficiency. Regarding that fact, the D-glucofuranose and its derivatives have been designed by the quantum calculation, molecular docking, ADMET and SAR analysis. For molecular docking, the cancer protease (3hb5) and triple-negative breast cancer protease (4pv5) are selected for study whereas the binding affinity of cancer protease (3hb5) is found at ranging from -6.20 to -10.40 kcal/mol, and it is slightly lower than triple-negative breast cancer protease (4pv5). Next, the molecular dynamic has performed to make the validation of docking complex. In our forthcoming study, it has shown that the 03, 05, and 08 compounds could be considered the potential drug comparison with standard drug. These three drugs completed all the criteria, including high binding energy, non-toxic, non-carcinogenic, and highly soluble in biological system.
Electronics band structures, the total density of state, the partial density of state and optical properties were investigated by DFT method for A 2 InAgCl 6 (A= Cs, Na, K, and Rb). Moreover, the band gap of Na 2 InAgCl 6 , K 2 InAgCl 6 , Rb 2 InAgCl 6 and Cs 2 InAgCl 6 were calculated at 1.039 eV, 1.041 eV, 1.039 eV and 1.089 eV by GGA with PBE, 0.784 eV, 0.769 eV, 0.775 eV and 0.770 eV by LDA with CA-PZ and 1.310 eV, 1.152 eV, 1.180 eV and 1.169 eV by GGA with RPBE functionals. The density of states (DOS) and partial density of states (PDOS) were evaluated. Among of used functionals, GGA with RPBE functional has considered the appropriate and acceptable method for calculation of band gap where the 1.310 eV of band gap was reported for Cs 2 InAgCl 6 , which is close to experimental value at 1.370 eV. The crystal, Na 2 InAgCl 6 , has considered as the best perovskites cell among other four due to low band gap, and the main cause is revealed that it has attached the lightest Na atom to convey the low band gap as lower surface or atomic size atom.
In this research, the fourteen commonly used antiviral drugs were investigated through the computational tools against CoV-19 or SARS-2, as well as two small bioactive molecules from the cannabis plant, Tetrahydrocannabinol (THC) and Cannabinol (CBN). Thus, these were selelcted for molecular docking against main protein (5r7y) and spike protein (6xs6) of coronavirus. It was illustrated that the binding energies of M pro for Pimodivir,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
