  Aromatic glycosyl disulfide derivatives: Evaluation of their inhibitory activities against Trypanosoma cruzi

  摘要：

  Aromatic oligovalent glycosyl disulfides and some diglycosyl disulfides were tested against three different Trypanosoma cruzi strains. Di-(beta-D-galactopyranosyl-dithiomethylene) benzenes 2b and 4b proved to be the most active derivatives against all three strains of cell culture-derived trypomastigotes with IC50 values ranging from 4 to 11 mu M at 37 degrees C. The inhibitory activities were maintained, although somewhat lowered, at a temperature of 4 degrees C as well. Three further derivatives displayed similar activities against at least one of the three strains. Low cytotoxicities of the active compounds, tested on confluent HeLa, Vero and peritoneal macrophage cell cultures, resulted in significantly higher selectivity indices (SI) than that of the reference drug benznidazole. Remarkably, several molecules of the tested panel strongly inhibited the parasite release from T. cruzi infected HeLa cell cultures suggesting an effect against the intracellular development of T. cruzi amastigotes as well.

  Synthesis and biological evaluation of a new class of glycoconjugated disulfides that exhibit potential anticancer properties

  摘要：

  A synthetic strategy, based on the in situ generation of sulfenic acids and their thermolysis in the presence of thiols, was developed for obtaining a collection of polyvalent disulfides in which a benzene scaffold accommodates two or three flexible arms connecting saccharide moieties. Targeting carbohydrate metabolism or carbohydrate-binding proteins may constitute important approaches in the discovery process of new therapeutic anticancer agents. Therefore, a preliminary screening to ascertain the cytostatic/cytotoxic potential of this new class of enantiopure glycoconjugated disulfides has been conducted. Among them, products with two disulfide arms, harbouring galactose rings, induced high levels of apoptosis on U937 histiocytic lymphoma cells, but lower levels of cell death on peripheral blood mononuclear cells from healthy donors. Further experiments indicated that apoptosis induced by these glycoconjugated bis(disulfides) in U937 cells corresponds to the Bcl-2-sensitive, intrinsic form of apoptotic cell death. The bioinvestigation was extended to a panel of human cancer cell lines with different levels of malignancy and resistance to chemotherapeutic agents. Compounds under study proved to induce detectable levels of cell death towards all the tested cancer cell lines. (C) 2012 Elsevier Ltd. All rights reserved.
