This phenomenon was moderately, strongly, and completely prohibited in the presence of CYP2E1 inhibitor 1-aminobenzotriazole, SULT1A1 inhibitor pentachlorophenol and both in combination, respectively.

Mutagenicity of NDELA in V79-hCYP2E1-hSULT1A1 cells was abolished by the CYP2E1 inhibitor 1-aminobenzotriazole, but unaffected by the SULT1A1 inhibitor pentachlorophenol.

1600620 Yamazaki H, Oda Y, Funae Y, Imaoka S, Inui Y, Guengerich FP, Shimada T: Participation of rat liver cytochrome P450 2E1 in the activation of N-nitrosodimethylamine and N-nitrosodiethylamine to products genotoxic in an acetyltransferase-overexpressing Salmonella typhimurium strain (NM2009). Carcinogenesis. 1992 Jun;13(6):979-85.

Part of the pathway involved in the activation of nitrosamines is suggested to be acetylation of alkyldiazohydroxides formed by P450 or acetylesterase, because the genotoxic activity of N-nitrosomethylacethoxymethylamine in S.typhimurium NM2009 could be inhibited by the O-acetyltransferase inhibitor pentachlorophenol.
