An advance in the selective acylation of polyamines having identical or similar amine functions is reported. While nucleophilicity differences between the various amine functions are slight, the corresponding conjugate acids exhibit pKa values
Linear and branched alkyl-esters and amides of gallic acid and other (mono-, di- and tri-) hydroxy benzoyl derivatives as promising anti-HCV inhibitors

Linear and branched compounds that contain two, three or five units of galloyl (3,4,5-trihydroxybenzoyl) or its isomer 2,3,4-trihydroxybenzoyl, as well as other mono- or dihydroxybenzoyl moieties have been synthesized. These molecules have been evaluated for their in vitro inhibitory effects against a wide panel of viruses showing preferential activity against HIV and HCV. Our structure-activity relationship studies demonstrated that the 2,3,4-trihydroxybenzoyl moiety provides better antiviral activities than the galloyl (3,4,5-trihydroxybenzoyl) moiety that is present in natural green tea catechins. This observation can be of interest for the further rational exploration of compounds with anti-HCV/HIV properties. The most notable finding with respect to HIV is that the tripodal compounds 43 and 45, with three 2,3,4-trihydroxybenzoyl moieties, showed higher activities than linear compounds with only one or two. With respect to HCV, the linear compounds, 52 and 41, containing a 12 polymethylene chain and two 2,3 di- or 2,3,4 tri-hydroxybenzoyl groups respectively at the ends of the molecule showed good antiviral efficiency. Furthermore, the anti-HCV activity of both compounds was observed at concentrations well below the cytotoxicity threshold. A representative member of these compounds, 41, showed that the anti-HCV activity was largely independent of the genetic make-up of the HCV subgenomic replicon and cell lines used.
Specific Sequestering Agents for the Actinides. 3. Polycatecholate Ligands Derived from 2,3-dihydroxy-5-sulfobenzoyl Conjugates of Diaza- and Tetraazaalkanes

As part of a program to develop specific sequestering agents for the actinides, we have reported the synthesis of N,N',N'',N'''-tetra(2,3-dihydroxybenzoyl)tetraazaalkanes.These tetra(DBH) amides are potentially octadentate ligands via coordination of the
