5-iodowillardiine 5-iodowillardiine 5-iodowillardiine is a selective agonist for the kainate receptor, with only limited effects at the ampa receptor. it is selective for kainate receptors composed of glur5 subunits. it is an excitotoxic neurotoxin in vivo, but has proved highly useful for characterising the subtypes and function of the various kainate receptors in the brain and spinal cord. 5-iodowillardiine names iupac name (2s)-2-amino-3-(5-iodo-2,4-dioxopyrimidin-1-yl)propanoic acid identifiers cas number 140187-25-3 n 3d model (jsmol) interactive imageinteractive image chembl chembl121915 y chemspider 394358 y drugbank db02818 y iuphar/bps 4071 pubchem cid 447196 comptox dashboard (epa) dtxsid90332246 inchi inchi=1s/c7h8in3o4/c8-3-1-11(2-4(9)6(13)14)7(15)10-5(3)12/h1,4h,2,9h2,(h,13,14)(h,10,12,15)/t4-/m0/s1 ykey: axxyltbqiqbtes-bypyzucnsa-n yinchi=1/c7h8in3o4/c8-3-1-11(2-4(9)6(13)14)7(15)10-5(3)12/h1,4h,2,9h2,(h,13,14)(h,10,12,15)/t4-/m0/s1key: axxyltbqiqbtes-bypyzucnbl smiles c1=c(c(=o)nc(=o)n1c(c(=o)o)n)io=c(o)(n)cn1/c=c(/i)c(=o)nc1=o properties chemical formula c7h8in3o4 molar mass 325.061 g/mol except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references
