ned-19 ned-19 trans-ned-19 is a drug which acts as a potent and selective antagonist of the endogenous calcium channel opener nicotinic acid adenine dinucleotide phosphate (naadp), thereby reducing the normal naadp-mediated calcium flux without blocking calcium channels directly. it is used in research into the functions of naadp signalling inside many different cell types. ned-19identifiers iupac name (1r,3s)-1-methyl]-4-methoxyphenyl]-2,3,4,9-tetrahydro-1h-pyridoindole-3-carboxylic acid cas number1354235-96-3pubchem cid1427628chemspider24604981chebichebi:138526chemblchembl1222013chemical and physical dataformulac30h31fn4o3molar mass514.601 g·mol−13d model (jsmol)interactive image smiles coc1=c(c=c(c=c1)2c3=c(c(n2)c(=o)o)c4=cc=cc=c4n3)cn5ccn(cc5)c6=cc=cc=c6f inchi inchi=1s/c30h31fn4o3/c1-38-27-11-10-19(16-20(27)18-34-12-14-35(15-13-34)26-9-5-3-7-23(26)31)28-29-22(17-25(33-28)30(36)37)21-6-2-4-8-24(21)32-29/h2-11,16,25,28,32-33h,12-15,17-18h2,1h3,(h,36,37)/t25-,28+/m0/s1key:fuhceerdbrgpqz-lbnvmwsvsa-n
