  Lipoic acid analogs with enhanced pharmacological activity

  摘要：

  Lipoic acid (1,2-dithiolane-3-pentanoic acid) is a pharmacophore with unique antioxidant and cytoprotective properties. We synthesized a library based upon the condensation of natural and unnatural amino acids with the carboxylic acid moiety of lipoic acid. SAR studies were conducted using a cardiac ischemia-reperfusion animal model. Cytoprotective efficacy was associated with the R-enantiomer of the dithiolane. Potency of library compounds was dictated by the acidic strength of the adduct. alpha-N-[(R)1,2-dithiolane-3-pentanoyl]-L-glutamyl-L-alanine, designated CMX-2043, was chosen for further pharmacologic evaluation.
