Nonpeptide Inhibitors of Measles Virus Entry
摘要:
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-mu M blockade of the MV, one of which (AS-48) exhibits IC50 0.6-3.0 mu M 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.

One‐pot radicals: Cobalt(III)–carbene radicals, generated by metallo‐radical activation of diazo compounds and N‐tosylhydrazone sodium salts with cobalt(II) complexes of porphyrins, readily undergo radical addition to carbon monoxide, allowing the catalytic production of ketenes. These ketenes subsequently react with various amines, alcohols and imines in one‐pot tandem transformations to produce differently

Dehydrogenative oxidation of amines is a relevant process in metal-mediated catalysis, with the amines being either substrates or ligands. Transformation of amine- into imine-type ligands in the coordination sphere of a transition metal can be an important catalyst activation process. The behaviour of secondary pyridin-2-ylmethanamine (pma) ligands in the corresponding rhodium and iridium complexes

discovery of coupling reagents which gave an unprecedented impeteus to the development of peptide synthesis. Of course, in these methods high reactivity of carboxyl function towards nucleophilic attack is achieved, but rigorous conditions such as use of base, temperature etc. are required. Moreover, the electron withdrawing groups like halogen which enhances the electrophilicity of carboxyl carbon, increases
An efficient sodium bicarbonate promoted aerobicoxidation reaction to prepare N-monosubstituted α-ketoamides in the presence of n-tetrabutylammonium hydrogensulfate (TBAHS) was described. This reaction provides a very simple and convenient synthetic route to N-monosubstituted α-ketoamides from easily available aryl- or heteroarylacetamides in good to high yields without using toxic reagents and

The effective equilibrium constants K′CK′C expressed through the total concentrations of the reagents for the synthesis of N-phenylacetyl-derivatives in aqueous medium from phenylaceticacid and various primary amino compounds have been determined with penicillin acylase as a catalyst. Broad specificity of penicillin acylase (EC 3.5.1.11) to amino components made possible to investigate the acylation
