l-694247 l-694247 l-694247 is a somewhat selective 5-ht1d agonist, with a 10-fold greater affinity for the 5-ht1b receptor, and 25-fold greater affinity for the 5-ht1a receptor. when l-694247 was injected intraventricularly in dehydrated rats, it inhibited water intake. pre-treatment with a 5-ht1d antagonist abolished this effect. administration of l-694,247 to normally hydrated rats had no effect on water intake. l-694247 names preferred iupac name n--1,2,4-oxadiazol-3-yl}methyl)phenyl]methanesulfonamide identifiers cas number 137403-12-4 n 3d model (jsmol) interactive image chebi chebi:92341 chembl chembl39317 chemspider 116658 pubchem cid 132059 comptox dashboard (epa) dtxsid20160175 inchi inchi=1s/c20h21n5o3s/c1-29(26,27)25-16-5-2-13(3-6-16)10-19-23-20(28-24-19)14-4-7-18-17(11-14)15(8-9-21)12-22-18/h2-7,11-12,22,25h,8-10,21h2,1h3key: hkxmqlispyelrd-uhfffaoysa-n smiles cs(=o)(=o)nc1ccc(cc1)cc2nc(on2)c3ccc4c(c3)c(c4)ccn properties chemical formula c20h21n5o3s molar mass 411.48 g mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
