For studies of pharmacokinetics and drug metabolism of these compounds, the version with a metabolically suitable carbon-14 label were required [7, 8]. Indole, benzopyrrole, is a yellow crystalline powder with unpleasant aroma. It has the pyrrole ring (five-membered unsaturated ring structure composed of four carbon atoms and one nitrogen atom) which is fused to benzene ring. There are tautomerer called indolenine (unsubstituted 3H-indole) and structural isomer, isoindole. But they are unstable. A benzopyrene is an organic compound with the formula C 20 H 12. Structurally speaking, the colorless isomers of benzopyrene are pentacyclic hydrocarbons and are fusion products of pyrene and a phenylene group. Two isomeric species of benzopyrene are benzo [ a ]pyrene and the less common benzo [ e ]pyrene. They belong to the chemical class of ...
