Abstract
A crucial role in the regulation of DNA replication is played by the highly conserved CDC kinase. The CDC7 kinase could serve as a target for therapeutic intervention in cancer. The primary heterocyclic substance is pyrazole, and its derivatives offer great potential as treatments for cancer cell lines. Here, we synthesized the two pyrazole derivatives: 4-(2-(4-chlorophenyl)hydrazinyl)-5-methyl-2-tosyl-1H-pyrazol-3(2H)-one (PYRA-1) and 4-(2-(2,4-difluorophenyl)hydrazinyl)-5-methyl-2-tosyl-1H-pyrazol-3(2H)-one (PYRA-2). The structural confirmation of both the compounds at the three-dimensional level is characterized using single crystal X-ray diffraction and density functional theory. Furthermore, the in silico chemical biological properties were derived using molecular docking and molecular dynamics (MD) simulations. PYRA-1 and PYRA-2 crystallize in the P-1 (a = 8.184(9), b = 14.251(13), c = 15.601(15), α = 91.57(8), β = 97.48(9), 92.67(9), V = 1801.1(3) 3, and Z = 2) and P21/n (a = 14.8648(8), b = 8.5998(4), c = 15.5586(8), β = 116.47(7), V = 1780.4(19) 3, and Z = 4), space groups, respectively. In both PYRA-1 and PYRA-2 compounds, C-H···O intermolecular connections are common to stabilize the crystal structure. In addition, short intermolecular interactions stabilizes with C-H···π and π-π stacking. Crystal packing analysis was quantified using Hirshfeld surface analysis resulting in C···H, O···H, and H···H contacts in PYRA-1 exhibiting more contribution than in PYRA-2. The conformational stabilities of the molecules are same in the gas and liquid phases (water and DMSO). The docking scores measured for PYRA-1 and PYRA-2 with CDC7 kinase complexes are -5.421 and -5.884 kcal/mol, respectively. The MD simulations show that PYRA-2 is a more potential inhibitor than PYRA-1 against CDC7 kinase.

Abstract
The unprecedented coronavirus SARS-CoV-2 outbreak at Wuhan, China, caused acute respiratory infection to humans. There is no precise vaccine/therapeutic agents available to combat the COVID-19 disease. Some repurposed drugs are saving the life of diseased, but the complete cure is relatively less. Several drug targets have been reported to inhibit the SARS-CoV-2 virus infection, in that TMPRSS2 (transmembrane protease serine 2) is one of the potential targets; inhibiting this protease stops the virus entry into the host human cell. Camostat mesylate, nafamostat, and leupeptin are the drugs, in which the first two drugs are being used for COVID-19 and leupeptin also tested. To consider these drugs as the repurposed drug for COVID-19, it is essential to understand their binding affinity and stability with TMPRSS2. In the present study, we performed the molecular docking and molecular dynamics (MD) simulation of these molecules with the TMPRSS2. The docking study reveals that leupeptin molecule strongly binds with TMPRSS2 protein than the other two drug molecules. The RMSD and RMSF values of MD simulation confirm that leupeptin and the amino acids of TMPRSS2 are very stable than the other two molecules. Furthermore, leupeptin forms interactions with the key amino acids of TMPRSS2 and the same have been maintained during the MD simulations. This structural and dynamical information is useful to evaluate these drugs to be used as repurposed drugs, however, the strong binding profile of leupeptin with TMPRSS2, suggests, it may be considered as a repurposed drug for COVID-19 disease after clinical trial.

Abstract
The selective estrogen receptor downregulators (SERDs) are the new emerging class of drugs that are used for the treatment of endocrine resistance breast cancer. Elacestrant (ELA) is a new SERD, currently it is in phase II clinical trial. To understand the ELA-ERα interactions, the molecular docking analysis has been carried out. The ELA molecule binds with the helices H3, H5, H6, and H11 and forms important intermolecular interactions. In addition to this, the tetrahydronapthalene and phenyl rings of ELA are forming T-shaped π···π interactions with the Phe404 and Trp383 residues. Further to understand the stability and flexibility of ELA molecule in the active site of wild and mutated L536S ERα, 100ns molecular dynamics (MD) simulation was performed for both complexes. Interestingly, the MD analysis of wild complex revealed an interaction between ELA and the Asn532 of H11, which is an essential interaction for the downregulation/degradation of ERα, whereas this interaction is not observed in the mutated complex. The drug binding mechanism and H12 dynamics have been elucidated from the analysis of hydrogen bonding interactions and the secondary structure analysis. To explore the binding affinity of ELA molecule, the binding free energy and normal mode analyses were carried out. The per residue decomposition analysis also performed, which shows the contribution of individual amino acids. The principal component analysis and residue interaction network analysis were used to identify the modifications and the interaction between the residues. From the results of different analysis, the inhibition mechanism and downregulation of ERα-ELA complex has been investigated. © 2019 Wiley Periodicals, Inc.
