The present invention concerns a dynamic mixture obtained by combining, in the presence of water, at least one diamine derivative that includes at least one benzylamine moiety, with at least one active aldehyde or ketone. The inventive mixture is capable of releasing in a controlled and prolonged manner the active compound, in particular those that are perfuming ingredients, into the surrounding environment.
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.
