Molecular dynamics simulations with coarse-grained or simplified Hamiltonians have proven to be an effective means of capturing the functionally important long-time and large-length scale motions of proteins and RNAs. Originally developed in the context of protein folding, structure-based models (SBMs) have since been extended to probe a diverse range of biomolecular processes, spanning from pr...

studying the interaction of pharmaceutical ionic liquids with human serum albumin (hsa) can help investigating whether or not ionic liquid formation can enhance pharmacological profile of the discrete ingredients. in this respect, in the present work, the interactions of benzalkonium ibuprofenate, as a well-known active pharmaceutical ionic liquid, benzalkonium chloride, and also sodium ibuprof...

Background: The outbreak of the COVID-19 pandemic caused by SARS-CoV-2 has triggered intense scientific research into possible therapeutic strategies that can combat ravaging disease. One such is inhibition an important enzyme affects physiological process virus. enzyme, Guanine-N7 Methyltransferase responsible for capping mRNA to conceal it from host’s cellular defense. aim study: This study a...

Introduction and Aim:Epidermal Growth Factor Receptor tyrosine kinase is a well-known widely studied cancer therapeutic target protein. Based on the reported anticancer activity of pyrimidines, series 13 compounds are designed. In present studythe EGFR domain targeted with designed compounds.
 Materials Methods:With missing residue in crystallized structure, modelled using homology modelli...

Purpose: To develop a new drug that inhibits viral attachment and entry for the treatment of HIV/AIDS patients. Methods: Two Protein Databank (PDB) crystal structures of HIV-1 gp120-CD4 complexes, namely, 1RZK and 1G9N, were mutated at amino acid position 43 to a biphenylalanine (biPhe-43) residue. FireDock web server was used for the docking experiments and 5ns molecular dynamics (MD) using Gr...

Molecular dynamics (MD) simulations of 12 aqueous systems of the NADH-dependent enoyl-ACP reductase from Mycobacterium tuberculosis (InhA) were carried out for up to 20-40 ns using the GROMACS 4.5 package. Simulations of the holoenzyme, holoenzyme-substrate, and 10 holoenzyme-inhibitor complexes were conducted in order to gain more insight about the secondary structure motifs of the InhA substr...

To investigate the effect of C-terminal helix on the stability of the FF domain, we studied the native domain FF3-71 from human HYPA/FBP11 and the truncated version FF3-60 with C-terminal helix being deleted by molecular dynamics simulations with GROMACS package and GROMOS 43A1 force field. The results indicated that the structures of truncated version FF3-60 were evident different from those o...

Ion channels are of universal importance for all cell types and play key roles in cellular physiology and pathology. Increased insight into their functional mechanisms is crucial to enable drug design on this important class of membrane proteins, and to enhance our understanding of some of the fundamental features of cells. This review presents the concepts behind the recently developed simulat...
