p38 Kinase plays a vital role in inflammation mediated by tumor necrosis factor-alpha (TNFalpha) and interleukin-1beta (IL-1beta) pathways and inhibitors of p38 kinase provide effective approach for the treatment of inflammatory diseases. Pyridinyl and pyrimidinyl imidazoles, selectively inhibit p38alpha MAP kinase, are useful in the treatment of(More)
A comprehensive database named, protein ligand interaction database (PLID), is created with 6295 ligands bound to proteins extracted from the protein data bank (PDB). This is by far the most comprehensive database of physico-chemical properties, quantum mechanical descriptors and the residues present in the active site of proteins. It is a publicly(More)
Choline kinase (ChoK) is reported to involve in cell signaling pathways and cell growth by regulating the intermediate, phosphocholine (PCho), which is the first step to biosynthesis a membrane phospholipid, phosphatidylcholine. The PCho levels are overexpressed due to elevated activation of the protein under carcinogenesis conditions. ChoK has thus evolved(More)
A series of furanochalcone derivatives have been designed and synthesized. Molecular modeling studies were carried out to probe into the mechanism of binding of chalcone inhibitors and understand the structure–activity relationship to identify the contribution of scaffolds and groups in the synthesized analogs to biological activity. The three-dimensional(More)
Virtual screening emerged as an important tool in our quest to access novel drug like compounds. There are a wide range of comparable and contrasting methodological protocols available in screening databases for the lead compounds. The number of methods and software packages which employ the target and ligand based virtual screening are increasing at a(More)
Choline kinase (ChoK) is a cytosolic enzyme present in various tissues, which catalyzes the phosphorylation of choline to form phosphorylcholine (PCho) in the presence of ATP and magnesium. ChoK is important for the generation of two major membrane phospholipids, phosphatidylcholine (PC) and sphingomyelin (SM) and subsequently for the cell division. ChoK(More)
P-type ATPases constitute a ubiquitous superfamily of cation transport enzymes, responsible for carrying out actions of paramount importance in biology such as ion transport and expulsion of toxic ions from cells. The harmonized toggling of gates in the extra- and intracellular domains explain the phenomenon of specific cation binding in selective(More)
MP2(FULL)/6-311++G** calculations are performed on the cation-pi complexes of Li+ and Mg2+ with the pi-face of linear (ethylene, butadiene, hexatriene, and octatetraene) and cyclic (benzene, naphthalene, anthracene, phenanthrene and naphthacene) unsaturated hydrocarbons. The interaction energy is found to increase systematically as the size of the pi-system(More)
