[[http://www.uniprot.org/uniprot/NR1I2_HUMAN NR1I2_HUMAN]] Nuclear receptor that binds and is activated by variety of endogenous and xenobiotic compounds. Transcription factor that activates the transcription of multiple genes involved in the metabolism and secretion of potentially harmful xenobiotics, drugs and endogenous compounds. Activated by the antibiotic rifampicin and various plant metabolites, such as hyperforin, guggulipid, colupulone, and isoflavones. Response to specific ligands is species-specific. Activated by naturally occurring steroids, such as pregnenolone and progesterone. Binds to a response element in the promoters of the CYP3A4 and ABCB1/MDR1 genes.<ref>PMID:9727070</ref> <ref>PMID:11668216</ref> <ref>PMID:11297522</ref> <ref>PMID:19297428</ref> <ref>PMID:12578355</ref> <ref>PMID:18768384</ref>

== Publication Abstract from PubMed ==
 +
The P2X4 receptor is a ligand-gated ion channel that is expressed on a variety of cell types especially those involved in inflammatory and immune processes. High-throughput screening let to a new class of P2X4 inhibitors with substantial CYP 3A4 induction in human hepatocytes. A structure-guided optimization with respect to decreased PXR binding was started. It was found that the introduction of larger and more polar substituents on the ether linker led to less PXR binding while maintaining the P2X4 inhibitory potency. This translated into significantly reduced CYP-induction for compounds 71 and 73. Unfortunately, the in vivo PK profiles of these compounds were insufficient for the desired profile in humans. However, BAY-1797 (10) was identified and characterized as potent and selective P2X4 antagonist. This compound is suitable for in vivo studies in rodents, anti-inflammatory and anti-nociceptive effects of BAY-1797 were demonstrated in a mouse CFA inflammatory pain model.
