The major UGT isoforms identified were UGT1A6, UGT1A7, and UGT1A9 for 4-methylumbelliferone; UGT1A6 and UGT1A8 for 1-naphthol; UGT2B7 for naloxone; UGT1A3 and UGT2B7 for ketoprofen; and UGT1A4 for trifluoperazine.

Other effective UGT1A8 substrates (> 0.1 nmol/mg/min) included 9-OH-benzo [a] pyrene, 1-naphthol, 4-methylumbelliferone, 7-hydroxycoumarin, chrysin, quercetin, 4-nitrophenol, and estriol.

In the rat intestine, UDP-glucuronosyltransferase (UGT) isoforms were highly induced by oral administration of 2-naphthoflavone, as shown by intestinal UGT activity toward 1-naphthol (1-NA).

When macrophage cells cultured in plates were exposed to 1-naphthol and 3-hydroxybenzo-[a] pyrene (3-OH-B [a] P), these glucuronides increased in the medium, indicating that macrophages glucuronidated the chemicals.
Northern blot analysis revealed that UGT1A7 mRNA was induced by LPS treatment.

The UGT isoform present in KYN-2 cells corresponds to UGT1*6, whereas in Mz-Hep-1 cells the UGT isoform present was different from UGT1*6 and UGT1*7.
