Abstract
The sudden outbreak of the COVID-19 pandemic has currently taken approximately 2.4 million lives, with no specific medication and fast-tracked tested vaccines for prevention. These vaccines have their own adverse effects, which have severely affected the global healthcare system. The discovery of the main protease structure of coronavirus (Mpro/Clpro) has resulted in the identification of compounds having antiviral potential, especially from the herbal system. In this study, the computer-associated drug design tools were utilised to analyze the reported phytoconstituents of Nigella sativa for their antiviral activity against the main protease. Fifty-eight compounds were subjected to pharmacological parameter analysis to determine their lead likeness in comparison to the standard drugs (chloroquine and nirmatrelvir) used in the treatment of SARS-CoV-2. Nearly 31 compounds were docked against five different SARS-CoV-2 main proteases, and all compounds showed better binding affinity and inhibition constant against the proteases. However, dithymoquinone and campesterol displayed the best binding scores and hence were further subjected to dynamics and MMPBSA study for 100 ns. The stability analysis shows that dithymoquinone and campesterol show less variation in fluctuation in residues compared to standard complexes. Moreover, dithymoquinone exhibited higher binding affinity and favorable interaction followed by campesterol as compared to the standard drug. The in silico computational analysis provides a promising hit for regulating the main proteases activity.Communicated by Ramaswamy H. Sarma.

Abstract
An important role has been considered for the vascular endothelial growth factor receptor 2 (VEGFR-2) in the angiogenesis process, so that its inhibition is an important scientific way for cancer treatment. In this work, new thienopyrimidine derivatives were synthesized and evaluated. Compared with sorafenib, the majority of the target compounds had antiproliferative activity against the PC3, HepG2, MCF7, SW480, and HUVEC cell lines, especially 9h with IC50 values of 4.5-15.1 μM, confirming the noticeable cytotoxic effects on the listed cell lines (PC3, HepG2, SW480, and HUVEC). Analyses by flow cytometry on SW480 and HUVEC cells revealed that 9n, 9k, 9h, and 9q led to apoptotic cell death. The result of the chick chorioallantoic membrane assay showed that 9h effectively reduced the number of corresponding blood vessels. Finally, the inhibitory effect on VEGFR-2 phosphorylation was considered as the outcome of Western blot analysis of compound 9h.

Computational identification of bioactive compounds from Cydonia oblonga Mill. against hepatocellular carcinoma by targeting pTEN and HBx-interacting protein. J Mol Model 2022; 28:191. [PMID: 35711004 DOI: 10.1007/s00894-022-05170-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 05/25/2022] [Indexed: 10/18/2022]
Abstract
Phytochemicals derived from Cydonia oblonga have been investigated for their anti-oxidant and anti-cancer activities in various cancer cell lines. The reported bioactive compounds are evaluated in silico to develop a novel antagonist against pTEN (phosphatase and tensin homolog) and HBx (hepatitis B X-interacting protein) to target hepatocellular carcinoma. Lower expression of pTEN or higher expression of HBx represents the progression of hepatocellular carcinoma. This research is intended to identify the best candidate who interacts with our target proteins (pTEN and HBx) from the quince seeds by using computational methodologies. The ternary structures of the proteins and phytochemicals are retrieved from the online databases (RCSB and PubChem). The drug likeness analysis of the reported seventeen compounds was done, but only five follow the selection criteria. ADMET profiling of these five compounds was done, followed by docking analysis and molecular dynamics study of the best complexes to determine the stability of the complexes. A docking study revealed that caffeoylquinic acids (CQA) derivatives have the significant inhibitory potential of 3-O-caffeoylquinic acid (3CQA) and 5-O-caffeoylquinic acid (5CQA) with binding affinity of - 7.53 and - 7.49 against pTEN and - 5.94 and - 6.01 against HBx in comparison to the doxorubicin. The average root mean square deviation and root mean square fluctuation values for protein-ligand complexes were found quite stable compared to the standard, while parameters like gyration and SASA (solvent-accessible surface area) supported the complexes significant binding and stability. The results obtained from the evaluation show that 3CQA and 5CQA have the best stability, especially with the pTEN protein target. Hence, these compounds have to be considered for detailed experimental studies to understand their biological function against hepato-carcinoma.

Abstract
α-Fluorinated chalcones were prepared and evaluated for their cell growth inhibitory properties against six human cancer cell lines. The most potent chalcone 4c demonstrated excellent selective toxicity against cancer cells versus normal human cells, with IC50 values at nanomolar concentration ranges against 5 cancer cell lines. A further study revealed that 4c could bind to the colchicine site of tubulin, disrupt the cell microtubule networks, and effectively inhibit tubulin polymerisation. Cellular-based mechanism studies elucidated that 4c arrested MGC-803 cell cycle at G2/M phase. In addition, 4c dose-dependently caused Caspase-induced apoptosis of MGC-803 cells through mitochondrial dysfunction. Notably, compound 4c was found to inhibit the HUVECs tube formation, migration, and invasion in vitro. Furthermore, our data suggested that treatment with 4c significantly reduced MGC-803 cells metastasis and proliferation in vitro. Overall, this work showed that chalcone hybrid 4c is a potent inhibitor of tubulin assembly with prominent anti-angiogenesis and anti-cancer properties.

Molecular Docking and Dynamics Simulation Analysis of Thymoquinone and Thymol Compounds from Nigella sativa L. that Inhibits P38 Protein: Probable Remedies for Hepatocellular Carcinoma. Med Chem 2020; 16:350-357. [PMID: 31038073 DOI: 10.2174/1573406415666190416165732] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Revised: 04/09/2019] [Accepted: 04/09/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Currently, a novel antagonist against p38 is being designed and applied to inhibit hepatocellular carcinoma. Protein-ligand interaction plays a major role in the identification of the possible mechanism for the pharmacological action. The involvement of p38 remains an important target for anticancer drug development as its activation induces apoptosis in hepatoma cells. OBJECTIVE The aim is to identify the best candidate from the plants of N. sativa which binds with the hepatocellular carcinoma (HCC) targets by computational approach. MATERIALS AND METHODS The reported phytoconstituents such as thymoquinone and thymol present in the plant, N. sativa were docked with the HCC target such as p38. Structures of phytoconstituents were prepared using ChemDraw Ultra 10 software and converted into its 3D PDB structure and minimized using Discovery Studio client 2.5. The target protein, p38 was retrieved from RCSB PDB. Lipinski's rule and ADMET toxicity profiling were carried out on the phytoconstituents of the N. sativa, and the compounds were further promoted for molecular docking and MD simulation analysis. RESULTS The docking results revealed promising inhibitory potential of thymoquinone against p38 with binding energy of -7.67 kcal/mole as compared to its known standard doxorubicin having binding energy of -6.68 kcal/mol respectively. Further, molecular dynamic (MD) simulations for 5ns were conducted for optimization, flexibility prediction, and determination of folded p38 stability. The p38-thymoquinone complex was found to be quite stable with RMSD value of 0.2 nm. CONCLUSION Obtained results propose thymoquinone binding energy on the selected targets. Hence, this compound bears outstanding potential against hepatocellular carcinoma and has to be taken up for experimental work against hepatocellular carcinoma.

Molecular simulation studies to reveal the binding mechanisms of shikonin derivatives inhibiting VEGFR-2 kinase. Comput Biol Chem 2020; 90:107414. [PMID: 33191109 DOI: 10.1016/j.compbiolchem.2020.107414] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 10/17/2020] [Accepted: 10/29/2020] [Indexed: 12/20/2022]
Abstract
Traditional vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitors can manage angiogenesis; however, severe toxicity and resistance limit their long-term applications in clinical therapy. Shikonin (SHK) and its derivatives could be promising to inhibit the VEGFR-2 mediated angiogenesis, as they are reported to bind in the catalytic kinase domain with low affinity. However, the detailed molecular insights and binding dynamics of these natural inhibitors are unknown, which is crucial for potential SHK based lead design. Therefore, the present study employed molecular modeling and simulations techniques to get insight into the binding behaviors of SHK and its two derivates, β-hydroxyisovalerylshikonin (β-HIVS) and acetylshikonin (ACS). Here the intermolecular interactions between protein and ligands were studied by induced fit docking approach, which were further evaluated by treating QM/MM (quantum mechanics/molecular mechanics) and molecular dynamics (MD) simulation. The result showed that the naphthazarin ring of the SHK derivates is vital for strong binding to the catalytic domain; however, the binding stability can be modulated by the side chain modification. Because of having electrostatic potential, this ring makes essential interactions with the DFG (Asp1046 and Phe1047) motif and also allows interacting with the allosteric binding site. Taken together, the studies will advance our knowledge and scope for the development of new selective VEGFR-2 inhibitors based on SHK and its analogs.

Abstract
The vascular endothelial growth factor receptor-2 signaling pathway promotes the formation of new blood vessels, and vascular endothelial growth factor receptor-2 tyrosine kinase exists in both active and inactive conformations. Novel indole–benzimidazole and indole–benzothiazole derivatives joined by different linkers are designed and synthesized as inhibitors of vascular endothelial growth factor receptor-2 tyrosine kinase. All the synthesized compounds were evaluated for their cytotoxicity against four human cancer cell lines (HeLa, HT29, A549, and MDA-MB-435) and human umbilical vein endothelial cell. Meanwhile, the inhibitory activities against vascular endothelial growth factor receptor-2 are estimated in vitro and the binding interactions with dual conformations of vascular endothelial growth factor receptor-2 tyrosine kinase are evaluated by molecular docking. Compounds 5a–c and 14 show inhibitory activity against vascular endothelial growth factor receptor-2 tyrosine kinase and promising cytotoxicity, specifically with IC50 values ranging between 0.1 and 1 μM, which imply broad-spectrum antitumor activity. These results provide a deep insight into potential structural modifications for developing potent vascular endothelial growth factor receptor-2 tyrosine kinase inhibitors.

Abstract
The B-cell lymphoma-2 (Bcl-2) family proteins have been attributed to be the key regulators in programmed cell death and apoptosis with a prominent role in human cancer. Understanding the fundamental principles of cell survival and death have been the main cornerstone in cancer drug discovery for identification of novel anticancer agents. In this context the Bcl-2 family of anti-and pro-apoptotic proteins provide an excellent opportunity for development of anticancer agents, as blocking the Bcl-2 or Bcl-XL functionally promotes apoptosis in tumor cells and also sensitize them to chemo- and radiotherapies. The present study reports the identification of novel Aplysin analogs as BCL-2 inhibitors from a sequential virtual screening approach using drug-like, ADMET, docking, pharmacophore filters and molecular dynamics simulation. We identified promising Aplysin analogs that have a potential to be Bcl-2 inhibitors just like the standard drug Obatoclax. One of the compound analog 11 was identified to be a promising inhibitor of Bcl-2 in the docking, pharmacophore and simulation based models.The molecular modeling information provided here can be vital in designing of the novel Bcl-2 inhibitors.
