  Synthesis and biological evaluation of new clofibrate analogues as potential PPARα agonists

  摘要：

  Clofibrate is a lipid-profile modifying agent belonging to the fibrate class of drugs. Fibrates are known to exhibit their beneficial effects by activating peroxisome proliferator-activated receptor-alpha (PPARalpha) and used in the treatment of dyslipidemia and atherosclerosis and for the prevention of heart failure. Hereby, the preparation of two new sets of clofibrate analogues, ethyl 2-(4-chlorophenoxy)-3-oxoalkanoates and ethyl 2-(4-chlorophenoxy)-3-hydroxyalkanoates is described starting from commercially available 3-oxoalkanoates in fair to good yields. Treatment of 3-oxoalkanoates with SO2Cl2 yielded the corresponding 2-chloro-3-oxoalkanoates, that were then converted into 2-(4-chlorophenoxy)-3-oxoalkanoates by reacting with sodium or caesium 4-chlorophenate. Reduction of the keto group with NaBH4 afforded the corresponding 2-(4-chlorophenoxy)-3-hydroxyalkanoates in very high yields and with variable diastereoselectivity. Biological evaluation of the compounds was performed by a transactivation assay in a transiently transfected monkey kidney fibroblast cell line. The newly synthesised clofibrate analogues failed to show noticeable levels of PPAR activation at concentrations where clofibrate showed an evident activity, suggesting that the structural modifications caused the loss of PPAR activity.

  Reduction of oxoesters 1b-d and 1fg in the presence of different yeast strains (Saccharomyces cerevisiae DSM 11285, S. cerevisiae CBS 7336, Cryptococcus curvatus ATCC 20509, Candida hombicola ATCC 22214, Trigonopsis variabilis DSM 70714, Kluyveromyces marxianus CBS 6556) affords hydroxy esters 2b-d and 2fg with diastereoisomeric excesses (de) up to > 99%. Hydrolytic enzyme(s) contained in the yeasts catalyzed to some extent the hydrolysis of the oxoesters to the corresponding acids, which undergo decarboxylation followed by reduction of the carbonyl moiety.
