bp-897 bp-897 bp-897 is a drug used in scientific research which acts as a potent selective dopamine d3 receptor partial agonist with an in vitro intrinsic activity of ~0.6 and ~70x greater affinity for d3 over d2 receptors and is suspected to have partial agonist or antagonist activity in vivo. it has mainly been used in the study of treatments for cocaine addiction. a study comparing bp-897 with the potent, antagonistic, and highly d3 selective sb-277,011-a found, "sb 277011-a (1–10 mg/kg) was able to block cue-induced reinstatement of nicotine-seeking, indicating that drd3 selective antagonism may be an effective approach to prevent relapse for nicotine. in contrast, bp 897 did not block the cue-induced reinstatement of nicotine-seeking or nicotine-taking under the fr5 schedule." bp-897clinical dataatc codenoneidentifiers iupac name n-butyl]naphthalene-2-carboxamide cas number314776-92-6 ypubchem cid3038495iuphar/bps7625chemspider2302059 nunii20ple5w821chemblchembl25236 ncomptox dashboard (epa)dtxsid60953482 echa infocard100.150.041 chemical and physical dataformulac26h31n3o2molar mass417.553 g·mol−13d model (jsmol)interactive image smiles coc1ccccc1n3ccn(cc3)ccccnc(=o)c4ccc2ccccc2c4 inchi inchi=1s/c26h31n3o2/c1-31-25-11-5-4-10-24(25)29-18-16-28(17-19-29)15-7-6-14-27-26(30)23-13-12-21-8-2-3-9-22(21)20-23/h2-5,8-13,20h,6-7,14-19h2,1h3,(h,27,30) nkey:mnhdkmdlojscgn-uhfffaoysa-n n ny (what is this?)
