Since 2003, highly pathogenic H5N1 influenza viruses have been the cause of large-scale death in poultry and the subsequent infection and death of over 140 humans. At present, there are only three licensed anti-Influenza drugs namely Relenza (Zanamivir - ZMV), Tamiflu (Oseltamivir - OTV) and Amantadine/Rimantadine. The latter targets the M2 ion channel(More)
The structure-based design of novel H5N1 neuraminidase inhibitors is currently a research topic of vital importance owing to both a recent pandemic threat by the worldwide spread of H5N1 avian influenza and the high resistance of H5N1 virus to the most widely used commercial drug, oseltamivir-OTV (Tamiflu). A specific criterion used in this work for(More)
Molecular mechanisms for the gamma-ionizing radiation (IR) resistance of human prostate cancer cells, PC-3, are not quite clear. Since the low-LET-IR effects are primarily manifested by the generation of reactive oxygen species (ROS), the IR-induced expressions both of ROS-metabolizing antioxidant enzymes, such as Mn- and CuZn superoxide dismutases (SODs)(More)
In the context of a recent pandemic threat by the worldwide spread of H5N1 avian influenza, the high resistance of H5N1 virus to the most widely used commercial drug, oseltamivir (Tamiflu), is currently an important research topic. Herein, molecular bases of the mechanism of H5N1 NA resistance to oseltamivir were elucidated using a computational approach in(More)
The potential of flavonoids to act as anti-tumor agents has been recognized but not fully understood because flavonoids are acting at several stages in cancer progression with distinct structure-function relationships. A whole family of structurally different flavonoids is herein described by reviewing some critical aspects of their pro-oxidant behavior in(More)
The whole family of structurally distinct flavonoids has been recognized as a valuable source of prospective anticancer agents. There is experimental evidence demonstrating that some flavonoids, like flavopiridol (FLP) and quercetin (QUE), bind to DNA influencing their key physiological function. FLP is involved in the combined mode of interaction(More)
In our previous study, a protein engineering approach, accounting for the effects of single point mutations of the binding site residues on the stability of 22 thiazolo[4,5-d]pyrimidines in complex with the intracellular kinase domain of EGFR (PDB ID: 1XKK), was established in a systematic manner to be an efficient strategy for the identification of(More)
The potential of quercetin (QUE), being a member of the whole family of structurally different flavonoids, to serve as an anti-tumor agent has been recognized, but not fully understood. The interactions between DNA and a series of the flavonoids have so far been mainly investigated using a variety of experimental techniques. Herein, the specificity of QUE(More)
Epidermal growth factor receptors (EGFRs) belong to the ErbB family of receptor tyrosine kinases (TKs). Based on the role of EGFR signaling pathway in malignant progression of various types of tumors, a growing interest in the use of EGFR-TK inhibitors as probes for molecular imaging of EGFR-overexpressing tumors via positron emission tomography (PET) and(More)
