The outbreak of avian influenza A subtype H5N1 virus has raised a global concern for both animal as well as human health. Recently, drug resistance in H5N1 infections has been widely reported due to neuraminidase mutations. Consequently, the understanding of inhibitor-neuraminidase interactions at the molecular level represents the main goal of our study.(More)
The cyclin dependent kinases (CDKs), each with their respective regulatory partner cyclin that are involved in the regulation of the cell cycle, apoptosis, and transcription, are potentially interesting targets for cancer therapy. The CDK6 complex with cyclin D (CDK6/cycD) drives cellular proliferation by phosphorylation of specific key target proteins. To(More)
Molecular dynamics simulations of the drug-resistant M2 mutants, A30T, S31N, and L26I, were carried out to investigate the inhibition of M2 activity using amantadine (AMT). The closed and open channel conformations were examined via non- and triply protonated H37. For the nonprotonated state, these mutants exhibited zero water density in the conducting(More)
The recent outbreak of the novel 2009 H1N1 influenza in humans has focused global attention on this virus, which could potentially have introduced a more dangerous pandemic of influenza flu. In the initial step of the viral attachment, hemagglutinin (HA), a viral glycoprotein surface, is responsible for the binding to the human SIA alpha2,6-linked(More)
The stability of the thymidylate synthase (TS)/2-deoxyuridine-5-monophosphate (dUMP)/5,10-methylene-5,6,7,8-tetrahydrofolate (mTHF) ternary complex formation and Michael addition are considered as important steps that are involved in the inhibition mechanism of the anticancer prodrug 5-fluorouracil (5-FU). Here, the effect of three different halogen(More)
Beta cyclodextrin (βCD) is well-known as a potent drug carrier improving drug solubility, stability, and bioavailability. The water layer adjacent to the membrane surface and lipophilic domain itself are a controlling barrier for drug transport. However, the molecular details of the interaction between βCD and the lipid membrane has not yet been clearly(More)
Hepatitis C virus (HCV) causes an infectious disease that manifests itself as liver inflammation, cirrhosis, and can lead to the development of liver cancer. Its NS3/4A serine protease is a potent target for drug design and development since it is responsible for cleavage of the scissile peptide bonds in the polyprotein important for the HCV life cycle.(More)
Steroid 5α-reductase type II is a membrane-associated enzyme in an oxidoreductase family. This enzyme, which is found in male sexual organs, plays the important biological actions toward steroid metabolism. Overexpression of 5α-reductase type II has affected the balance between testosterone and dihydrotestosterone, which implicates the androgenic disorders,(More)
Behçet's disease (BD), a multi-organ inflammatory disorder, is associated with the presence of the human leukocyte antigen (HLA) HLA-B*51 allele in many ethnic groups. The possible antigen involvement of the major histocompatibility complex class I chain related gene A transmembrane (MICA-TM) nonapeptide (AAAAAIFVI) has been reported in BD symptomatic(More)
