Structure Optimization of Neuraminidase Inhibitors as Potential Anti-influenza (H1N1Inhibitors) Agents Using QSAR and Molecular Docking Studies

چکیده مقاله:
The urgent need of neuraminidase inhibitors (NI) has provided an impetus for understanding the structure requisite at molecular level. Our search for selective inhibitors of neuraminidase has led to the identification of pharmacophoric requirements at various positions around acyl thiourea pharmacophore. The main objective of present study is to develop selective NI, with least toxicity and drug like ADMET properties. Electronic, Steric requirements were defined using kohnone nearest neighbour- molecular field analysis (kNN-MFA) model of 3D-QSAR studies. Results generated by QSAR studies showed that model has good internal as well as external predictivity. Such defined requirements were used to generate new chemical entities which exhibit higher promising predicted activities. To check selective binding of designed NCE’s docking studies were carried out using the crystal structure of the neuraminidase enzyme having co-crystallized ligand Oseltamivir. Thus, Molecular modelling provided a good platform to optimize the acyl thiourea pharmacophore for designing its derivatives having potent anti-viral activity.

متن کاملNeuraminidase inhibitors as anti-influenza virus agents.
Influenza virus neuraminidase (NA) catalyses the cleavage of sialic acid residues terminally linked to glycoproteins and glycolipids and plays an important role in the replication of the virus. Recently, several potent NA inhibitors have been synthesized based on the rational design of mimicking the transition state of the sialic acid cleavage. Zanamivir and oseltamivir (GS 4104, the prodrug of...
متن کاملIn Silico Screening Studies on Methanesulfonamide Derivatives as Dual Hsp27 and Tubulin Inhibitors Using QSAR and Molecular Docking
The expression of heat shock protein 27 (Hsp27) as a chaperone protein, is increased in response to various stress stimuli such as anticancer chemotherapy. This phenomenon can lead to survive of the cells and causes drug resistance. In this study, a series of methanesulfonamide derivatives as dual Hsp27 and tubulin inhibitors in the treatment of cancer were applied to quantitative structure–act...

A series of 2-benzoxazolinone, diazocoumarin and quinazoline derivatives have been shown to inhibit HIV replication in cell culture. To understand the pharmacophore properties of selected molecules and design new anti-HIV agents, quantitative structure–activity relationship (QSAR) study was developed using a descriptor selection approach based on the stepwise method. Multiple linear regression ...
