Abstract

The cyclic AMP phosphodiesterase (CAMP PDE) inhibitor and cardiotonic agent lixazinone (N-cyclohexyl-N-methyl-4-[(1, 2, 3, 5-tetrahydro-2-oxoimidazo [2, lb] quinazolin-7-yl) oxy] butyramide, RS-82856, 1) and its acid and base addition salts were found to be insufficiently soluble in formulations suitable for intravenous administration. These results prompted an investigation into potential prodrugs with enhanced aqueous solubility designed to deliver ...
