Carvedilol is a uniquely effective drug for the treatment of cardiac arrhythmias in patients with heart failure. This activity is in part because of its ability to inhibit store-overload-induced calcium release (SOICR) through the RyR2 channel. We describe the synthesis, characterization, and bioassay of ca. 100 compounds based on the carvedilol motif to identify features that correlate with and optimize SOICR inhibition. A single-cell bioassay was employed on the basis of the RyR2-R4496C mutant HEK-293 cell line in which calcium release from the endoplasmic reticulum through the defective channel was measured. IC50 values for SOICR inhibition were thus obtained. The compounds investigated contained modifications to the three principal subunits of carvedilol, including the carbazole and catechol moieties, as well as the linker chain containing the β-amino alcohol functionality. The SAR results indicate that significant alterations are tolerated in each of the three subunits.

It was shown by PMR spectroscopy that the conformational equilibrium in the glycidyl and thioglycidyl ethers and esters of 1-adamantanol and 1-adamantanecarboxylic acid is displaced toward the most polar conformation.It was found that the geminal spin-spin coupling constant of the protons of the exocyclic methylene group in 1-adamantyl thioglycidyl ether increases with increase in the polarity of the medium.
