Class II major histocompatibility complex (MHC II) molecules as expressed by antigen-presenting cells are heterodimeric cell-surface glycoprotein receptors that are fundamental in initiating and propagating an immune response by presenting tumor-associated antigenic peptides to CD4(+)/T(H) cells. The loading efficiency of such peptides can be improved by(More)
Disordered regions of proteins often bind to structured domains, mediating interactions within and between proteins. However, it is difficult to identify a priori the short disordered regions involved in binding. We set out to determine if docking such peptide regions to peptide binding domains would assist in these predictions.We assembled a redundancy(More)
Alzheimer's disease, known to be associated with the gradual loss of memory, is characterized by low concentration of acetylcholine in the hippocampus and cortex part of the brain. Inhibition of acetylcholinesterase has successfully been used as a drug target to treat Alzheimer's disease but drug resistance shown by butyrylcholinesterase remains a matter of(More)
Multiple Drug Resistant (MDR) bacteria are no more inhibited by the front line antibiotics due to extreme resistance. Methicillin Resistant Staphylococcus aureus (MRSA) is one of the MDR pathogens notorious for its widespread infection around the world. The high resistance acquired by MRSA needs a serious concern and efforts should be carried out for the(More)
A novel series of anticytokine N-benzyl pyridinone derivatives that targets p38α MAP kinase has been analyzed by utilizing a combination of molecular modeling techniques. Statistically significant structure-based 3D-QSAR models were generated for both CoMFA and CoMSIA, and validated through acceptable predictive ability to support both internal and external(More)
Aminoacyl-tRNA synthetases (aaRSs) catalyze the esterification of a specific amino acid. There are two classes of aminoacyl-tRNA synthetases. Class I usually exists as a monomeric or dimeric form and has two highly conserved sequence motifs. Functionally, it aminoacylates at the 2'-OH of an adenosine nucleotide. While, class II normally exists as a dimeric(More)
The kinome is a protein kinase complement of the human genome, categorized as serine/threonine and tyrosine kinases. These kinases catalyze phosphorylation reaction by using ATP as phosphoryl donor. Proviral Integration Site for Moloney Murine Leukemia Virus (PIM) kinase encodes serine/threonine protein kinases that recognized as proto-oncogene, responsible(More)
Benzamide sulfonamide and its derivatives were identified as potent inhibitors of carbonic anhydrase-II (bovine carbonic anhydrase-II (bCA-II) and human recombinant carbonic anhydrase-II (hCA-II)) with IC50 values 0.06–0.28 μM and 0.09–0.58 μM, respectively. Different kinetics parameter, such as V max, K m , and K i , were determined. Molecular docking(More)
Dilated cardiomyopathy is a disease of left ventricular dysfunction accompanied by impairment of the β1-adrenergic receptor (β1-AR) signal cascade. The disturbed β1-AR function may be based on an elevated sympathetic tone observed in patients with heart failure. Prolonged adrenergic stimulation may induce metabolic and electrophysiological disturbances in(More)
Leprosy is caused by Mycobacterium leprae a major health concern in several countries of the world particularly in Asia and Africa. The preventive measurement has been adopted by the combined efforts of the leprosy burden countries and WHO. However, the situation is getting worse due to the emergence of the resistant strains of the M. leprae. The continuous(More)
