Design, synthesis and evaluation of trifluoromethane sulfonamide derivatives as new potent and selective peroxisome proliferator-activated receptor α agonists
摘要:
Starting from the structure of 5, a two-step strategy was applied to identify a new generation of trifluoromethane sulfonamides as potent PPAR alpha agonists. Synthesis, in vitro and in vivo evaluation of the most potent compound are reported. (c) 2007 Elsevier Ltd. All rights reserved.

campaigns, we decided to perform a systematic study on their promiscuity. An amount of 163 rhodanines, hydantoins, thiohydantoins, and thiazolidinediones were synthesized and tested against several targets. The compounds were also characterized with respect to aggregation and electrophilic reactivity, and the binding modes of rhodanines and relatedcompounds in published X-ray cocrystal structures were analyzed
A series of rhodanine derivatives was prepared. The synthetic approach, analytical and spectroscopic data of all synthesized compounds are presented. Lipophilicity of all the discussed rhodanine derivatives was analyzed using the RP-HPLC method. The compounds were tested for their ability to inhibit photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts and reduce chlorophyll content in freshwater alga Chlorella vulgaris. Structure-activity relationships between the chemical structure, physical properties and biological activities of the evaluated compounds are discussed. For majority of the tested compounds the lipophilicity of the compound and not electronic properties of the R1 substituent were decisive for PET-inhibiting activity. The most potent PET inhibitor was (5Z)-5-(4-bromobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (IC50 = 3.0 μmol/L) and the highest antialgal activity was exhibited by (5Z)-5-(4-chlorobenzylidene)-2-thioxo-1,3-thiazolidin-4-one (IC50 = 1.3 μmol/L).
