Determination of thevetin B in serum by fluorescence polarization immunoassay.[Pubmed:1420463]
J Pharm Biomed Anal. 1992 Jun;10(6):413-9.
Thevetin B, a cardiac glycoside of Thevetia neriifolia Juss. seeds, was determined in serum by fluorescence polarization immunoassay. Anti-digitoxin antibody was used, Thevetin B genin being structurally identical to digitoxigenin. Cross-reactivity of 94% was found by this method, for concentrations from 5 to 80 ng ml-1.
Method validation of a survey of thevetia cardiac glycosides in serum samples.[Pubmed:21376490]
Forensic Sci Int. 2012 Feb 10;215(1-3):146-51.
A sensitive and specific liquid chromatography tandem mass spectrometry (HPLC-ESI(+)-MS/MS) procedure was developed and validated for the identification and quantification of Thevetin B and further cardiac glycosides in human serum. The seeds of Yellow Oleander (Thevetia peruviana) contain cardiac glycosides that can cause serious intoxication. A mixture of six thevetia glycosides was extracted from these seeds and characterized. Thevetin B, isolated and efficiently purified from that mixture, is the main component and can be used as evidence. Solid phase extraction (SPE) proved to be an effective sample preparation method. Digoxin-d3 was used as the internal standard. Although ion suppression occurs, the limit of detection (LOD) is 0.27 ng/ml serum for Thevetin B. Recovery is higher than 94%, and accuracy and precision were proficient. Method refinement was carried out with regard to developing a general screening method for cardiac glycosides. The assay is linear over the range of 0.5-8 ng/ml serum. Finally, the method was applied to a case of thevetia seed ingestion.
Antagonism of biogenic amine-induced depression of cerebral cortical neurones by Na+, K+-ATPase in inhibitors.[Pubmed:141320]
Can J Physiol Pharmacol. 1977 Apr;55(2):170-9.
The effects of iontophoretically applied Na+-, K+-dependent adenosinetriphosphatase (Na+,K+-ATPase) (EC 3.6.1.3) inhibitors (ouabain, digitoxin, digitoxigenin, strophanthin K, strophanthidin, thevetin A and B, ethacrynate, and harmaline) on the depression of rat cerebral cortical neurones by noradrenaline, 5-hydroxytryptamine, and histamine have been studied. The inhibitors antagonized depressions of spontaneously active neurones evoked by these amines, but not those evoked by gamma-aminobutyric acid, adenosine, adenosine 5'-monophosphate, or calcium. The antagonistic potencies of the various inhibitors appeared to be proportional to their known potencies as inhibitors of Na+, K+-ATPase. The data therefore support the hypothesis that amines depress central neurones by activating an electrogenic sodium pump.
