6235789 Sugiyama S, Satoh T, Uzalp B, Ueno K, Igarashi T, Kitagawa H: Effects of a single administration of 6-aminonicotinamide on hepatic microsomal drug metabolism in rats. Arch Int Pharmacodyn Ther. 1984 May;269(1):20-33.

Of the first two steps of AM metabolism mediated by cytochrome P-450-coupled monooxygenase, the second step (from MAA to MA) was found to be more affected by 6-AN than the first one (from AM to MAA).

In contrast to ADHD and ODD, CD preferentially utilized hormone and neuropeptide genes These included CCK, CYP19 (aromatase cytochrome P-450), ESR1, and INS (p = 0.005).

These included the aryl hydrocarbon receptor, cytochrome P450, glutathione S-transferase, serine/threonine kinases, transcription factors, cyclooxygenase, ornithine decarboxylase, nitric oxide synthase, matrix metalloproteinases and tyrosine kinases.

Res Commun Chem Pathol Pharmacol. 1986 Apr;52(1):71-80.

4-Monomethylaminoantipyrine (MAA)-induced increase of hepatic drug metabolizing enzymes was suppressed by SKF 525-A.
This may be due to the partial binding of SKF 525-A to a portion of cytochrome P-450.

The results suggest that the formation of MAA, HM, HMAP, NORAP and OHAP from metronidazole and antipyrine is catalyzed by different cytochrome P-450 isozymes, which may be supplemented or substituted by PB or MC induced species.

Primary rat hepatocytes cultured for 24 h in the 3D matrix within the microchannel showed comparable or enhanced cytochrome P450 7-ethoxyresorufin-O-deethylation activity with static controls.

Present observation suggests the participation of cytochrome P-448 as well as cytochrome P-450 in the metabolism of AM.
