Mechanism of Action
Noscapine's antitussive effects appear to be primarily mediated by its sigma receptor agonist activity. Evidence for this mechanism is suggested by experimental evidence in rats. Pretreatment with rimcazole, a sigma specific antagonist, causes a dose-dependent reduction in antitussive activity of noscapine.
...EXCEPT FOR ITS ANTITUSSIVE EFFECT, IT HAS NO SIGNIFICANT ACTIONS ON CNS IN DOSES WITHIN THERAPEUTIC RANGE.

Anwendungen
BeschreibungA major constituent of opium (Papaver sornni!erurn), this phthalideisolquinoline base was probably first discovered by Derosne, but initially characterized by Robiquet who gave it the formula C23H3S0 7N, changed to that now accepted by Matthiesen and Foster. It crystallizes in colourless needles from EtOH and has [α]D - 198° (c 1.0, CHC13); - 146° (c 2.0, toluene); - 147° (c 1.59, C6H6) and + 50° (1 % HCl). The alkaloid is a weak, monoacidic, tertiary base, forming unstable salts with acids which are dissociated with H20. The hydrochloride crystallizes with varying amounts of H20, is very soluble in water, readily decomposing into basic salts on standing. The platinichloride is amorphous; the oxalate has m.p. 174°C;[α]20D + 39.5° (H20); the phthalate, m.p. 160°C; [α]22D + 115° (CHC13); sesquisulphate, colourless crystals of the hexahydrate and the picrate, m.p. 1 74-S°C. The (+)-bromocamphorsulphonate has m.p. 110- 120°C; [α]D + 100.7° (CHC13) and the corresponding (-)-bromocamphorsul_x0002_phonate, m.p. l80.SoC; [α]D + 29° (CHC13). The alkaloid yields an N-oxide which is a hygroscopic solid; [α]D + 135° (CHC13) furnishing a crystalline hydrochloride, m.p. 193°C; platinichloride, m.p. 175°C and a picrate, m.p. 130°C.The base is unstable to heat and when heated in a sealed tube yields a mixture of dimethylnornarcotine, methylnornarcotine and nornarcotine. On heating with H20 and 150°C, or on boiling with dilute acids, it is hydrolyzed to opianic acid and hydrocotarnine. Similar degradations are brought about by acid oxidation orreduction, e.g. Zn and dilute HCl gives hydrocotarnine and meconin while dilute HN03 yields cotarnine and opianic acid. Pharmacologically, narcotine resembles thebaine (q.v.) in its action, being a reflex stimulant rather than a narcotic.

Ergänzende Hinweise
DefinitionChEBI: A benzylisoquinoline alkaloid that is 1,2,3,4-tetrahydroisoquinoline which is substituted by a 4,5-dimethoxy-3-oxo-1,3-dihydro-2-benzofuran-1-yl group at position 1, a methylenedioxy group at positions 6-7 and a methoxy group at position 8. Obtained from p ants of the Papaveraceae family, it lacks significant painkilling properties and is primarily used for its antitussive (cough-suppressing) effects.
