Calf thymus DNA and M13mp9 RF DNA were modified with [ring-3H]2-naphthyl isocyanate (NIC) and analyzed by reverse-phase HPLC following enzymatic hydrolysis. In each case, essentially, a single radioactive component, which co-chromatographed with authentic N4-2-naphthyl-carbamoyl-2'-deoxycytidine (NCdC), was detected. In order to

The present study investigated the oxidative metabolism of 2-naphthyl isothiocyanate catalyzed by rat liver microsomes. Incubation of 2-naphthyl isothiocyanate, microsomes, and NADPH yielded either N,N'-di-2-naphthylurea or, on inclusion of 2-aminofluorene in the incubations, N-2-naphthyl-N'-2-fluorenylurea. These ureas were formed by the
