  Synthesis and structure–antifungal activity Relationships of 3-Aryl-5-alkyl-2,5-dihydrofuran-2-ones and Their Carbanalogues: further refinement of tentative pharmacophore group

  摘要：

  Two series of 3-(substituted phenyl)-5-alkyl-2,5-dihydrofuran-2-ones related to a natural product, (-)incrustoporine, were synthesized and their in vitro antifungal activity evaluated. The compounds with halogen substituents on the phenyl ring exhibited selective antifungal activity against the filamentous strains of Absidia corymbifera and Aspergillus fumigatus. On the other hand, the influence of the lenghth of the alkyl chain at C(5) was marginal. The antifungal effect of the most active compound against the above strains was higher than that of ketoconazole, and close to that of amphotericin B. In order to verify the hypothesis about a possible relationship between the Michael-accepting ability of the compounds and their antifungal activity, a series of simple carbanalogues, 2-(substituted phenyl)cyclopent-2-enones, was prepared and subjected to antifungal activity assay as well.

  Discovery of Potent and Selective SH2 Inhibitors of the Tyrosine Kinase ZAP-70

  摘要：

  A series of 1,2,4-oxadiazole analogues has been shown to be potent and selective SH2 inhibitors of the tyrosine kinase ZAP-70, a potential therapeutic target for immune suppression. These compounds typically are 200-400-fold more potent than the native, monophosphorylated tetrapeptide sequences. When compared with the high-affinity xi-1-ITAM peptide (Ac-NQL-pYNELNLGRREE-pYDVLD-NH2, wherein pY refers to phosphotyrosine) some of the best 1,2,4-oxadiazole analogues are approximately 1 order of magnitude less active. This series of compounds displays an unprecedented level of selectivity over the closely related tyrosine kinase Syk, as well as other SH2-containing proteins such as Src and Grb2. Gel shift studies using a protein construct consisting only of C-terminal ZAP-70 SH2 demonstrate that these compounds can effectively engage this particular SH2 domain.

  Electrochemical nickel-catalyzed syntheses of triphenylenes by a) reductive trimerization of ortho-dibromobenzenes or ortho-bromoarylsulfurofluoridates, or b) reductive cross-coupling of ortho-dibromobenzenes to 2,2’-diiodobiphenyls, are described. The former provides a practical means for the construction of triphenylene derivatives in up to 87% isolated yield at room temperature. For 1,2-dihalo-3-methylbenzenes

  A bis(phenylacetyl)benzene compound is reacted with a sulfoxide compound and a halide in the presence of an acid and an organic solvent. Also, a bis((-ketonitrile) compound is reacted in an acidic environment in the presence of water, a halide and a sulfoxide compound. It is thereby possible to produce bisbenzil compounds at a high yield and with high productivity.
