Norantipyrine glucuronide is a drug metabolite of norantipyrine, which is used to treat pain. Norantipyrine glucuronide has been shown to be resistant to cancer and it was found that the uptake of this metabolite was increased in wild-type mice. Norantipyrine glucuronide has been shown to inhibit multidrug resistance protein (MRP) 1 and 2, organic anion transporters (OATs), and breast cancer cells in vitro. In vivo studies have shown that the uptake of norantipyrine glucuronide is increased in proximal tubules of the human liver, which may be due to the inhibition of MRP1, MRP2, OAT1, and OAT3 by this drug.

Applications Antipyrine (A697500), a non-steroidal anti-inflammatory drug, is widely utilized as a probe for human oxidative drug metabolism. Antipyrine metabolites are formed by various hepatic cytochrome P450 enzymes. Norantipyrine Glucuronide is a metabolite of Antipyrine. References Akira K et al.
