Inhibitors of histonedeacetylases (HDAC) are emerging as a promising class of anti-cancer agents. A mercaptoamide functionality was designed as a bidentate zinc chelator and incorporated into the hydroxamicacidbased SAHA (1) scaffold in order to identify non-hydroxamate compounds as potential inhibitors of histonedeacetylases. Two sets of mercaptoamides 2 and 3 with varying spacer length were synthesized
Antibacterial activity of a novel series of 3-bromo-4-(1H-3-indolyl)-2,5-dihydro-1H-2,5-pyrroledione derivatives – An extended structure–activity relationship study
Compounds containing 3-bromo-2,5-dihydro-1H-2,5-pyrroledione and indole substructures were found to have antibacterial activity against resistant strains of Staphylococcus aureus and some other Gram positive bacteria. The investigated compounds exhibit minimal inhibition concentrations (MICs) lower than those of common antibiotics like vancomycin or ciprofloxacin. Activity against multiresistant strains suggests a mechanism of action different from common antibiotics. This might be important in circumventing existing resistance mechanisms. Here we report about the antibacterial activity in an extended structure-activity relationship study. (c) 2007 Elsevier Masson SAS. All rights reserved.
