  The complexation of lanthanum(III), europium(III), dysprosium(III), erbium(III), and lutetium(III) with D-gluconic acid (LH) was studied by pH potentiometry and NMR. The set of complexes formed in aqueous solutions and their stability constants β were determined, and the results were compared to those previously found for praseodymium(III) (S. Giroux et al., Polyhedron 2000, 19, 1567). A regular evolution

• Structure−Activity Relationships:  Analogues of the Dicaffeoylquinic and Dicaffeoyltartaric Acids as Potent Inhibitors of Human Immunodeficiency Virus Type 1 Integrase and Replication

  The dicaffeoylquinic acids (DCQAs) and dicaffeoyltartaric acids (DCTAs) are potent and selective inhibitors of human immunodeficiency virus type 1 (HIV-1) integrase. They also inhibit HIV-1 replication at nontoxic concentrations; Since integrase is an excellent target for anti-HIV therapy, structure-activity relationships were employed to synthesize compounds with: (1) improved potency against HIV-1 integrase, (2) improved anti-HIV effect in tissue culture, and (3) increased selectivity as indicated by low cellular toxicity. Thirty-four analogues of the DCTAs and DCQAs were synthesized and tested for cell toxicity, anti-HIV activity, and inhibition of HIV-1 integrase. Seventeen of the 34 analogues had potent activity against HIV-1 integrase ranging from 0.07 to >10 mu M. Seventeen analogues that were synthesized or purchased had no inhibitory activity against integrase at concentrations of 25 mu M. Of the biologically active analogues, 7 of the 17 inhibited HIV replication at nontoxic concentrations. The most potent compounds were D-chicoric acid, meso-chicoric acid, bis(3,4-dihydroxydihydrocinnamoyl)-L-tartaric acid, digalloyl-L-tartaric acid, bis(3,4-dihydroxybenzoyl)-L-tartaric acid, dicaffeoylglyceric acid, and bis(3,4-dihydroxyphenylacetyl)-L-tartaric acid. Anti-HIV activity of the active compounds in tissue culture ranged from 35 to 0.66 mu M. Structure-activity relationships demonstrated that biscatechol moieties were absolutely required for inhibition of integrase, while at least one free carboxyl group was required for anti-HIV activity. These data demonstrate that analogues of the DCTAs and the DCQAs can be synthesized which have improved activity against HIV integrase.

  Analogs of the methyl alpha -glycosides of the terminal residues of the O-specific polysaccharides (O-PS) of Vibrio cholerae O:1, serotype Inaba and Ogawa, have been prepared as probes to study their interaction with anti V. cholerae O:1 antibodies. They differ from the termini of the respective O-PSs in anomeric or absolute configuration of perosamine, position of the O-methyl group in D-perosamine, and nature of the N-acyl side chain.
