Predictive quantitative structure-toxicity and toxicophore models were developed for a diverse series of hERG K+ channel blockers, acting as anti-arrhythmic agents using QSAR+ module in Cerius2 and HypoGen module in Catalyst software, respectively. The 2D-QSTR analysis has been performed on a dataset of 68 molecules carefully selected from literature for(More)
In Silico predictive ADME/Tox screening of compounds is one of the hottest areas in drug discovery. To provide predictions of compound drug-like characteristics early in modern drug-discovery decision making, computational technologies have been widely accepted to develop rapid high throughput in silico ADMET analysis. It is widely perceived that the early(More)
The galactopeptide dendrimer GalAG2 ((β-Gal-OC6H4CO-Lys-Pro-Leu)4(Lys-Phe-Lys-Ile)2Lys-His-Ile-NH2) binds strongly to the Pseudomonas aeruginosa (PA) lectin LecA, and it inhibits PA biofilms, as well as disperses already established ones. By starting with the crystal structure of the terminal tripeptide moiety GalA-KPL in complex with LecA, a computational(More)
The spread of antibiotic resistant bacteria is one of the most pressing problems in human health today. [1] In the case of the opportunistic pathogen Pseudomonas aeruginosa, which causes lethal airway infections in cystic fibrosis and immuno-compromised patients, the formation of biofilms plays an important role in antibiotic resistance and disease(More)
The galactose specific lectin LecA mediates biofilm formation in the opportunistic pathogen P. aeruginosa . The interaction between LecA and aromatic β-galactoside biofilm inhibitors involves an intermolecular CH-π T-shape interaction between C(ε1)-H of residue His50 in LecA and the aromatic ring of the galactoside aglycone. The generality of this(More)
In this study, we have focused on the implication of a multiscreening approach in the evaluation of Pseudomonas aeruginosa deacetylase LpxC inhibitory activity of dual PDE4-TNFalpha inhibitors. A genetic function approximation (GFA) directed quantitative structure-activity relationship (QSAR) model was developed for LpxC inhibition on the basis of reported(More)
The target for the anti-inflammatory natural products like amentoflavone ( 2), which act by interfering with the proinflammatory cytokine pathway (e.g., TNF-alpha, IL-1beta, and NO synthase), is not yet well-defined. Data obtained from docking, electronic, and surface analyses shed some light on steric and electronic complementarity of these molecules to(More)
Aryl hydrazine and hydrazide analogues were synthesized based on p-tolyl hydrazine, isolated as a breakdown product of a secondary metabolite from the mushroom, Agaricus bisporus, and tested to be highly active molecule than 5-fluorouracil in in vitro anticancer studies. The synthesized analogues were tested for anticancer activity using NCI protocol.(More)
Resistance to drugs targeting human thymidylate synthase (TS) poses a major challenge in the field of anti-cancer therapeutics. Overexpression of the TS protein has been implicated as one of the factors leading to the development of resistance. Therefore, repressing translation by targeting the TS mRNA could help to overcome this problem. In this study, we(More)
