codeinone codeinone codeinone is 1/3 as active as codeine as an analgesic but it is an important intermediate in the production of hydrocodone, a painkiller about 3/4 the potency of morphine; as well as of oxycodone. the latter can also be synthesized from thebaine, however. codeinone names iupac name 3-methoxy-17-methyl-7,8-didehydro-4,5α-epoxymorphinan-6-one preferred iupac name (4r,4ar,7ar,12bs)-9-methoxy-3-methyl-2,3,4,4a,7,7a-hexahydro-1h-4,12-methanobenzofuroisoquinolin-7-one identifiers cas number 467-13-0 y 3d model (jsmol) interactive image chebi chebi:18399 y chembl chembl257627 y chemspider 4573639 y echa infocard 100.006.716 kegg c06171 y pubchem cid 5459910 unii 22b5aw0ann y comptox dashboard (epa) dtxsid70196909 inchi inchi=1s/c18h19no3/c1-19-8-7-18-11-4-5-13(20)17(18)22-16-14(21-2)6-3-10(15(16)18)9-12(11)19/h3-6,11-12,17h,7-9h2,1-2h3/t11-,12+,17-,18-/m0/s1 ykey: xyyvylmbezuesm-cmkmfdcusa-n yinchi=1/c18h19no3/c1-19-8-7-18-11-4-5-13(20)17(18)22-16-14(21-2)6-3-10(15(16)18)9-12(11)19/h3-6,11-12,17h,7-9h2,1-2h3/t11-,12+,17-,18-/m0/s1key: xyyvylmbezuesm-cmkmfdcubf smiles o=c1\c=c/54n(cc52c3c(o12)c(oc)ccc3c4)c properties chemical formula c18h19no3 molar mass 297.35 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 chemical structure codeinone can be described as the methylether of morphinone: 3-methyl-morphinone. codeinone can be also described as the ketone of codeine: codeine-6-one. apoptotic activity through renewed interest into possible anti-tumor activities of some of the opium alkaloids and derivatives, unrelated to their antinociceptive properties and habit-forming effects, the oxidation product of codeine has been found to induce cell death in three different human cancer cell lines in vitro.
