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)
BACKGROUND 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(More)
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)
Interleukin-2 (IL-2) is an immunoregulatory cytokine produced by T lymphocytes in response to antigen. It is a potent growth and differentiation factor for several cell-types and is structurally related to the four-helix bundle family of cytokines. Here, we report IL-2 inhibitory potential and computational studies on different series of chalcones,(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)
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)
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)
