naloxonazine naloxonazine naloxonazine is a potent, irreversible μ-opioid receptor antagonist. naloxonazine forms spontaneously in acidic solutions of naloxazone, and may be responsible for much or all of the irreversible μ opioid receptor binding displayed by the latter. naloxonazine names other names nih 10894; nsc 612113, bis- hydrazine dihydrochloride identifiers cas number 82824-01-9 y 3d model (jsmol) interactive image chembl chembl1618376 n chemspider 7850858 n iuphar/bps 1677 pubchem cid 9576413 unii bw5w4k4s7z y comptox dashboard (epa) dtxsid001002934 inchi inchi=1s/c38h42n4o6/c1-3-15-41-17-13-35-29-21-5-7-25(43)31(29)47-33(35)23(9-11-37(35,45)27(41)19-21)39-40-24-10-12-38(46)28-20-22-6-8-26(44)32-30(22)36(38,34(24)48-32)14-18-42(28)16-4-2/h3-8,27-28,33-34,43-46h,1-2,9-20h2/b39-23+,40-24+/t27-,28-,33+,34+,35+,36+,37-,38-/m1/s1 nkey: ajpsbxjnfjccbi-yohugvjrsa-n ninchi=1/c38h42n4o6/c1-3-15-41-17-13-35-29-21-5-7-25(43)31(29)47-33(35)23(9-11-37(35,45)27(41)19-21)39-40-24-10-12-38(46)28-20-22-6-8-26(44)32-30(22)36(38,34(24)48-32)14-18-42(28)16-4-2/h3-8,27-28,33-34,43-46h,1-2,9-20h2/b39-23+,40-24+/t27-,28-,33+,34+,35+,36+,37-,38-/m1/s1key: ajpsbxjnfjccbi-yohugvjrbh smiles c=ccn123(4(c5=c(c2)c=cc(=c5o4/c(=n/n=c\6/7oc8=c(c=cc9=c872((c9)n(cc2)cc=c)(cc6)o)o)/cc3)o)cc1)o properties chemical formula c38h42n4o6 molar mass 650.776 g·mol−1 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
