Novoseven eptacogalfa factor VII. noscapine [ban, inn] (narcotine i-a-narcotine) is an alkaloid from Corydalis cava (Corydalis tuberosa), Papaver somniferum and other Papaver spp. It is a by-product in extraction of morphine from opium, and one of the first alkaloids to be isolated. It can be used as a centrally acting ANTITUSSIVE, similar in pharmacology to codeine, novobiocin [ban, inn] (Albamycin ) is an antibiotic with ANTIBACTERIAL activity against Gram-positive bacteria. It is also a LEUKOTRIENE RECEPTOR ANTAGONIST.

Comparatively few simple isoquinoline alkaloids have been found to occur naturally. Until now such compounds have been encountered in three or four species of the Cactaceae, in a Chenopodiaceae [Salsola arbuscula Pall. (S. richteri Karel)], in three species belonging to the family of the Fumari-aceae [Corydalis pallida (Thunb.) Pers.,C. awrea Willd., C. tvherosa DC.] and in one Papaveraceae Papaver somniferum L.). While no doubt exists as to the native occurrence of the anhalonium and salsola isoquinolines, hy-drohydrastinine and hydrocotarnine may have been artifacts from the benzylisoquinoline alkaloids of Corydalis tuberosa and Papaver somniferum. 

Hydrohydrastinine, m.p. 66°, is a degradation product of hydrastine or of cotarnine, but, according to Spath and Julian (41), it also occurs in Corydalis tuberosa. 

Corydaline, C22H27O4N, was first isolated, obviously in impure form, from Corydalis tuberosa by Wackenroder (242). It has since been found in C. ambigua (24), C. aurea (28), C. Montana (29), and C. platycarpa (46). It crystallizes from hot methanol in stout hexagonal prisms and has... 

Corycavamine was obtained by Gadamer, Ziegenbein, and Wagner (88) from Corydalis tuberosa. It was purified by recrystallizing the sparingly soluble nitrate from hot water. The hydrochloride and hydriodide are crystalline and sparingly soluble in water.

Alkaloid from Corydalis cava (C. tuberosa), Papaver fugax, P. paeoniflorum, P. persicum and P. somniferum. By prod, in extraction of morphine from opium. One of the first alkaloids to be isol. (Fumariaceae, Papaveraceae). Antitussive agent, of similar potency to and poss. with some advantages over codeine. Mod. effective smooth muscle relaxant. Reference material used in elemental microanalysis. Stout needles (EtOH).
