Targeting flexibility: a structure-based computational study revealing allosteric HIV-1 protease inhibitors
نویسندگان
چکیده
We present the discovery of innovative low molecular weight inhibitors against human immunodeficiency virus 1 (HIV-1) protease. Structure-based virtual screening focused on potential allosteric surface cavities revealed these compounds [1]. To identify and prioritize such cavities we performed a molecular dynamics simulation were we concentrated on flexible and transient potential binding sites. For several time-points of the simulation we computed receptor-derived pharmacophore models in the so-called hinge region (’Exo site’) and screened a large screening compound library [2]. The most potent hit shows inhibition in a non-competitive mode of action.

Targeting structural flexibility in HIV-1 protease inhibitor binding.
HIV-1 protease remains an important anti-AIDS drug target. Although it has been known that ligand binding induces large conformational changes in the protease, the dynamic aspects of binding have been largely ignored. Several computational models describing protease dynamics have been reported recently. These have reproduced experimental observations, and have also explained how ligands gain ac...
متن کاملA QSAR Study of HIV Protease Inhibitors Using Computational Descriptors to Prediction of pki of Cycle Derivatives of Urea
Preventing and reducing the spread of HIV (HIV) has always been a concern in medical science. One of the most common ways to control the virus is using enzyme-blocking drugs. In this study, we attempted to predict the biological activity (PKi) of organic urea derivatives in protease inhibitor compounds using molecular modeling using QSAR (Quantitative Structure Activity Relation), which is the ...
متن کاملTargeting Dynamic Pockets of HIV-1 Protease by Structure-Based Computational Screening for Allosteric Inhibitors
We present the discovery of low molecular weight inhibitors of human immunodeficiency virus 1 (HIV-1) protease subtype B that were identified by structure-based virtual screening as ligands of an allosteric surface cavity. For pocket identification and prioritization, we performed a molecular dynamics simulation and observed several flexible, partially transient surface cavities. For one of the...
متن کاملResistance mechanism of human immunodeficiency virus type-1 protease to inhibitors: A molecular dynamic approach
Human immunodeficiency virus type 1 (HIV-1) protease inhibitors comprise an important class of drugs used in HIV treatments. However, mutations of protease genes accelerated by low fidelity of reverse transcriptase yield drug resistant mutants of reduced affinities for the inhibitors. This problem is considered to be a serious barrier against HIV treatment for the foreseeable future. In this st...
متن کاملTHE DESIGN, MODELING AND EVALUATION OF POTENTIAL HIV PROTEASE INHIBITORS USING BLITZ, AN INTERACTIVE COMPUTER GRAPHICS WORKING TOOL
Several nonpeptide small molecules were designed as potential inhibitors of HIV protease and their structures were constructed by computer-aided molecular modeling and docked iwo the active site of HIV protease. Models of the complexes of inhibitors and the HIV protease were refined using nonbonded and H-bonding terms. The refined energy of selected complexes showed that the designed inhib...
