چکیده

Measles virus (MV) is one of the most infectious pathogens known. Despite the existence of a vaccine, over 500,000 deaths/year result from MV or associated complications. Anti-measles compounds could conceivably reverse these statistics. Previously, we described a homology model of the MV fusion protein trimer and a putative binding site near the head-neck region. The resulting model permitted the identification of two nonpeptidic entry inhibitors. Here, we present the design, synthesis, and bioevaluation of several series of fusion inhibitors and describe their structure-activity relationships (SAR). Five simply substituted anilides show low-microM blockade of the MV, one of which (AS-48) exhibits IC50 = 0.6-3.0 microM across a panel of wild-type MV strains found in the field. Molecular field topology analysis (MFTA), a 2D QSAR approach based on local molecular properties (atomic charges, hydrogen-bonding capacity and local lipophilicity), applied to the anilide series suggests structural modifications to improve potency.

Construction of a Minigenome Rescue System for Measles Virus, AIK-c Strain

Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...

New Anti-Influenza Agents: Targeting the Virus Entry and Genome Transcription

Introduction: The emergence and spread of the pandemic H1N1 influenza virus in 2009 indicates a limitation in the strategy to control the infection, despite a long-established vaccination programme and approved antivirals. Production the proper vaccine against influenza is difficult due to the genetic recombination of virus in the event of pandemic and co-circulation of drug-resistance variants...

THE 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...

Design of a small-molecule entry inhibitor with activity against primary measles virus strains.

The incidence of measles virus (MV) infection has been significantly reduced in many nations through extensive vaccination; however, the virus still causes significant morbidity and mortality in developing countries. Measles outbreaks also occur in some developed countries that have failed to maintain high vaccine coverage rates. While vaccination is essential in preventing the spread of measle...
