Synthesis and evaluation of hexahydropyrimidines and diamines as novel hepatitis C virus inhibitors
摘要:
In order to identify novel anti-hepatitis C virus (HCV) agents we devised cell-based strategies and screened phenotypically small molecule chemical libraries with infectious HCV particles, and identified a hit compound (1) containing a hexahydropyrimidine (HHP) core. During our cell-based SAR study, we observed a conversion of HHP 1 into a linear diamine (6), which is the active component in inhibiting HCV and exhibited comparable antiviral activity to the cyclic HHP I. In addition, we engaged into the biological characterization of HHP and demonstrated that HHP does not interfere with HCV RNA replication, but with entry and release of viral particles. Here we report the results of the preliminary SAR and mechanism of action studies with HHP. (C) 2013 Elsevier Masson SAS. All rights reserved.

An extremely practical synthesis of 4,10-diaza-15-crown-5, 4,13-diaza-18-crown-6, and symmetrically N,N′-disubstituted derivatives thereof, is presented along with the first survey of cationbinding data for the 15-membered ring systems.

A novel family of redox-active dinuclear transition metal based cryptands self-assembled from dithiocarbamate ligands has been synthesised; depending upon the nature of the spacer groups these new cryptand systems have been shown to electrochemically recognise the binding of cations or anions.

A new short method to prepare N-alkyl-substitutedtriaza- and tetraaza-crowncompounds in good overall yields by reacting the appropriate oligoazaoxadiamine with allyloxymethyl-substituted triethylene glycol diiodide or diglycolyl dichloride (followed by reduction) is presented.
The Michael addition of bis(nitrogen or sulfur) nucleophiles to divinyl sulfone provides the corresponding macrocyclic adducts in good yields. The structures of some new macrocyclic sulfones are established by X-ray crystallographic analysis and NMR spectroscopy. The subsequent cleavage of benzyl or tosyl groups yields the unprotected macrocyclic sulfones.
