| CD59 is a potent inhibitor of the complement membrane attack complex (MAC) action that acts by binding to the C8 and C9 complements of the assembling MAC, thereby preventing incorporation of the multiple copies of C9 required for complete formation of the osmolytic pore. Human CD59 low expression leads to atherosclerosis. Therefore, computational approach methods were implemented herein to design novel activators for CD59. Crystal structure (PDB ID: 1CDR) of CD59 was investigated to locate N-acetyl glucosamine (NAG) active site residues (Leu1, Gln2, Val17, Asn18, Ser20, Ser21, Asp22 and Asp67). CD59 is known for its binding affinity towards NAG and Alpha-L-Fucose, hence, were explored against more than one million entries of Ligand.Info metadatabase to... |

| Parvovirus B19 is a common source of infection with a seroprevalence of 60-70% in the adult population. Human parvovirus causes several distinct clinical syndromes such as erythema, polyarthritis resembling rheumatoid arthritis, vasculitis, hydrops fetalis, myocarditis etc. Recent years have witnessed manifest increase in clinical knowledge of parvovirus B19-associated complications, diagnosis and treatment. Traditional immunosuppressive therapy being unsuccessful, anti-viral therapy might be worthy of consideration. Functional annotation of human parvoviral proteome may provide insights into role of viral proteome in its survival and pathogenic mechanisms. Availability of whole proteome in the open source aided functional annotation of protein using... |

| Yellow fever (YF), a mosquito-borne viral haemorrhagic fever, is one of the most lethal viral diseases. Despite the availability of vaccines, yellow fever virus (YFV) strikes an estimated 2, 00,000 persons world-wide each year and causes 30,000 deaths approximately. There are no approved antiviral therapies for the treatment of YFV disease in humans. YFV 17D strain RNA genome is of 10,862 nucleotides, which encodes three structural proteins (C, PrM, and E) and seven nonstructural proteins (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5). Identification of different protein functions facilitates a mechanistic understanding of YFV infection and opens novel means for drug development. Functional assignment of complete YFV proteome was done through support Vector... |

| Human myotrophin is the smallest ankyrin repeat protein implicated as a factor to induce cardiac hypertrophy. Activation of myotrophin was observed during acute myocardial infarction (MI). In acute coronary syndrome (ACS) patients, myotrophin acts as a self-governing predictor of major adverse cardiac events (MACE). Therefore, human myotrophin serves as an effective drug target for discovery of new potential drugs. Recent human myotropin inhibitors have poor pharmacological properties leading to intolerable side effects. Hence, ligand based virtual screening protocol of CADD method was pursued in the present study to propose new class potential myotrophin inhibitors. Docking was done by using Schrödinger software suite 2010 (maestro v9.1), docked... |

| Protein kinases are clinically relevant and attractive drug targets for most of the cancerous diseases. Ribosomal protein s6 kinase (P70s6 kinase) is a mitogen activated Ser/Thr protein kinase, essential for cell growth, G1 cell cycle progression and cell survival. Human P70s6 kinase is involved in different signaling pathways and phosphorylates the downstream S6 protein of the 40S ribosomal subunit there by controlling the translational activity. Over expression of human P70s6 or rapid amplification of gene (RPS6KB1) leads to rapid cell proliferation causing cancer in various organs of humans like colon, breast, ovary, etc. The over expression is principally due to activation of some phosphorylating sites or ATP binding sites in the domain regions. In the... |

| Human dual specificity mitogen-activated protein kinase kinase 4 (MAP2K4) is a direct activator of MAP kinases in response to various environmental stresses or mitogenic stimuli. Upon phosphorylation, MAP2K4 has been shown to activate MAPK8, MAPK9 and MAPK14/p38 but not MAPK1/ERK2 or MAPK3/ERK1. Over expression of MAP2K4 causes carcinogenic effects, such as ovarian cancer, colorectal cancer, prostate cancer and pancreatic cancer. Our present study was carried out to design a potent drug molecule against MAP2K4 to control over expression. As there is no experimentally determined structure for MAP2K4, the homology modeling technique of Modeller9v7 was implemented to generate a MAP2K4 3D model based on the co-crystal structure of MAP2K6 (PDB ID: 3FME) with... |

| The incidence of infective endocarditis (IE) represents the fourth leading cause of life-threatening infectious disease with a yearly incidence of 15,000 to 20,000 new cases despite advances in antimicrobial therapy, development of better diagnostic and surgical techniques. The diverse group of causative microbes of IE is one of major obstacle towards development of effective antimicrobial drug. This has triggered exploration of common potential novel drug target from available whole genome sequences of predominant pathogens causing IE in SVIMS hospital through comparative subtractive genomic approach and metabolic pathway analysis. Streptococcus mitis is the most predominant IE pathogen in SVIMS hospital. Thymidylate kinase of Streptococcus mitis plays a... |

| The advancement in therapeutic applications focused on specific macromolecular compounds of deregulated cell signaling pathways bestowed novel approach to design the ligands as drug molecules against several life threatening diseases such as Cancer. In humans, protein kinase A is one of the important kinases those were involved in cell signaling mechanism. cAMP, G-proteins and ATP molecules were required for activation of protein kinase A (PKA), upon activation, PKA catalytic subunits (PRKACA,PRKACB and PRKACG) undergoes many cellular functions like cell proliferations, cell cycle regulation, and survival of cells through acting on many substrates. Overexpression of extracellular cAMP dependent protein kinase A catalytic subunits (PRKACA) causes severe... |

| Human Fyn tyrosine kinase, a Src-family enzyme plays a pivotal role in the integrin mediated cell signaling pathway and is known to interact with several molecular signals including FAK and paxillin that accounts for morphogenic transformation leading to cancer. The present study was aimed to design a persuasive inhibitor for Fyn kinase. The crystal structure was optimized and energy minimized applying OPLS2001 force field in Maestro v9.0. The inhibitor binding site residues such as LEU-17, GLY-18, ASN-19, VAL-25, ALA-37, LYS-39, GLU-54, THR-82, GLU-83, TYR-84, MET-85, GLY-88, ALA-134, ASN-135, LEU-137, and ASP-148 were located from the Fyn kinase co-crystal structure with staurosporine. Three published inhibitors (staurosporine, Rosmarinic acid and... |

| Design of potential drug-like candidates for cardiovascular therapy is of interest in recent years. Elevated level of IGFBP-6 leads to perilous diseases like atherosclerosis, high output cardiac failure and myocardial infarction. The current IGFBP-6 inhibitors available in clinical practice are not having satisfactory anti-cardiovascular effects, leaving room for further improvement. Therefore, with an aim to propose a potent inhibitor to arrest the cardiovascular disease caused by IGFBP-6, tools of computer-aided drug designing were used for virtual screening from small molecule databases. Accordingly, IGFBP-6 tertiary structure was solved through nuclear magnetic resonance techniques retrieved from the protein data bank. Fifteen IGFBP-6 inhibitors were... |
