Étude de dérivés 5-arylidène-2-thiohydantoïnes à potentialité immunomodulatrice et anticancéreuse
摘要:
Various 5-arylidene-2-thiohydantoins, N3-substituted and/or S-substituted or not, were synthesized by aldolisation-crotonisation reaction from aromatic aldehydes or cyclic ketones and 2-thiohydantoins. These products, largely original, prepared as potentially active on chronic inflammatory diseases involving cellular-mediated immunity, display immunosuppressive activity which, however, remains clearly lower than ciclosporine's one. Searched in a few cases, anticancer activity is not obviously detected for any of tested products.
Synthesis of the 2-aza analogues of pyrrolizidine and spirooxindole-2-azapyrrolizidine hybrid, a spiro-tetracyclic scaffold possessing multiple contiguous stereocenters, by an exclusive regio-, chemo-, and diastereoselective multicomponent reaction in water is reported. This logical and didactical tactic has integrated the principles of an ideal organic synthesis, privileged substructure-based diversity-oriented

In a search of small molecules active against apoptosis-resistant cancer cells, a series of isatin-based heterocyclic compounds were synthesized and found to inhibit proliferation of cancer cell lines resistant to apoptosis. The synthesis of these compounds involved a condensation of commercially available, active methylene heterocycles with isatin proceeding in moderate to excellent yields. The heterocyclic scaffolds prepared in the current investigation appear to be a useful starting point for the development of agents to fight cancers with apoptosis resistance, and thus, associated with dismal prognoses.
