Carcinogenicity test of two unstaurated derivatives of N-nitrosopiperdine in Sprague-Dawley rats.


Two unsaturated derivatives of N-nitrosopiperidine (NP), N-nitroso-1,2,3,6-tetrahydropyridine (NTP) and N-nitrosoguvacoline (NGC), were administered to Sprague-Dawley rats as solutions in drinking water at concentrations equimolar (0.88X10(-3) M) with those used to test NP. NTP gave rise to hepatocellular tumors in contrast to the esophageal or olfactory… (More)
