What's the difference between brucine and vomicine?
Brucine
Definition:
(n.) A powerful vegetable alkaloid, found, associated with strychnine, in the seeds of different species of Strychnos, especially in the Nux vomica. It is less powerful than strychnine. Called also brucia and brucina.
Example Sentences:
(1) The strychnine-like effect was common to other glycine-antagonist tested, such as brucine, morphine and laudanosine.
(2) The hyper-irritability elicited by picrotoxin or penicillin G-K was associated with a relatively localized trigger zone in the face, while that elicited by strychnine or brucine spread beyond the trigeminal region to the first cervical dermatome.
(3) In the presence of large amounts of strychnine, brucine is isolated prior to colorimetric analysis by a quantitative thin layer chromatographic technique.
(4) This paper reports the determination of strychnine and brucine in different parts of Semen Strychni (the seeds of Strychnos nux-vomica and S. pierriana), and makes a comparison of the contents between the crude forms and processed products of the two seeds.
(5) Bisnor-dihydrotoxiferine seems to give dichlorometho compounds and N-oxides easily, analogous with strychnine and brucine.
(6) When the effects of quinine, brucine and caffeine on electrical responses in taste cells were examined, they all produced a depolarization associated with an increased input resistance.
(7) Sodium chloride (1,000 mM) enhanced the affinity of strychnine, brucine, isostrychnine, and the nonselective GABA antagonist pitrazepin for [3H]strychnine binding sites, whereas the affinities of glycine, beta-alanine, and taurine were reduced.
(8) The second was developed for the determination of brucine and is based on measuring the intensity of the violet color produced by treating brucine with nitric acid and methanolic stannous chloride.
(9) In contrast, brucine, the 2,3-dimethoxy derivative of strychnine, caused no increase in duplication frequencies under the identical conditions.
(10) The TMA curves of brucine, griseofulvin and phenobarbital were similar to that of indomethacin.
(11) We found that inferior olive lesioned rats had lower threshold to seizures induced by strychnine and brucine, both glycine antagonists.
(12) The natural abundance 13C-NMR spectra of brucine and strychnine were obtained using the pulse Fourier transform technique.
(13) The paper reports the experimental result of the simultaneous quantitative determination of strychnine (ST) and brucine(BR) in Semen Strychni by dual wavelength spectrophotometry.
(14) Nitrate were determined by the brucine method, while nitrates by the Griess colorimetric method.

(17) Binding was completely inhibited by glycine, alanine, alpha-aminobutyric acid, beta-aminoisobutyric acid, hypotaurine and strychnine, and to a lesser extent by 2,2-dimethyl-beta-alanine, brucine and gelsemine.
