Three strong alkaloidal monoamine oxidase (MAO) inhibitors, quinine (1), cinchonicinol ([ 1S,3'R,4'R]-3-(3-ethenyl-4-piperidinyl)-1-(4-quinolinyl)-1-propanol) (2) and cinchonaminone ([ 3'R,4'S]-2-[2-(3-ethenyl-4-piperidinyl)-acetyl]-1H-indole-3-ethanol) (3), were isolated from Cinchonae Cortex
The 2-oxidation activity on the pyrimidine ring of RS-8359, a MAO-A inhibitor, is the major metabolic pathway catalysed by aldehyde oxidase. This study investigated the species differences in the 2-oxidation activity by using liver cytosolic fractions from rats, mice, guinea-pigs, rabbits, dogs,
Cinchona alkaloids (quinine, quinidine, cinchonine, and cinchonidine) were incubated with partially purified aldehyde oxidase from rabbit or guinea pig liver. Reversed-phase HPLC methods were developed to separate the oxidation products from the parent drugs, and the metabolites were identified on
