  Suppression of store overload-induced calcium release by hydroxylated metabolites of carvedilol

  摘要：

  Carvedilol is a drug widely used in the treatment of heart failure and associated cardiac arrhythmias. A unique action of carvedilol is its suppression of store overload-induced calcium release (SOICR) through the cardiac ryanodine receptor (RyR2), which can trigger ventricular arrhythmias. Since the effects of carvedilol metabolites on SOICR have not yet been investigated, three carvedilol metabolites hydroxylated at the 3-, 4' and 5'-positions were synthesized and assayed for SOICR inhibition in mutant HEK 293 cells expressing the RyR2 mutant R4496C. This cell line is especially prone to SOICR and calcium release through the defective RyR2 channel was measured with a calcium-sensitive fluorescent dye. These results revealed that the 3- and 4'-hydroxy derivatives are slightly more effective than carvedilol in suppressing SOICR, while the 5'-analog proved slightly less active. Metabolic deactivation of carvedilol via these hydroxylation pathways is therefore insignificant. (C) 2015 Elsevier Ltd. All rights reserved.

  A simple synthetic route for active metabolites of carvedilol is reported. The metabolites 4'-hydroxycarvedilol and 5'-hydroxycarvedilol have exhibited high activity for -blockade. We have disclosed syntheses of 4'-hydroxycarvedilol and 5'-hydroxycarvedilol from commercially available vanillin and isovanillin, respectively.
