Imidazoleacetic acid ribotide

2-{1-[(3R,4S,5R)-3,4-dihydroxy-5-[(phosphonooxy)methyl]oxolan-2-yl]-1H-imidazol-4-yl}acetic acid

C10H15N2O9P (338.0515)


Imidazoleacetic acid ribotide (IAA-RP ) is an endogenous ligand that stimulates imidazol(in)e receptors. Experimental data suggest that IAA-RP may participate in transsynaptic signaling in brain, because it exists in brainstem neurons, exhibits depolarization-induced Ca2+-dependent release from P2 synaptosomal elements, has relatively high affinity for membrane-bound I-R sites, and produces physiological effects on exogenous application. IAA-RP is rapidly metabolized by phosphatases and ecto-5-nucleotidases. (PMID: 15365189) [HMDB] Imidazoleacetic acid ribotide (IAA-RP) is an endogenous ligand that stimulates imidazol(in)e receptors.
