Photochemical conversion of sanguinarine to oxysanguinarine
Journal of Photochemistry and Photobiology A: Chemistry, 1997Abstract The photochemical properties of the alkanolamine form of sanguinarine, a benzophenanthridine plant alkaloid, were studied using absorption, fluorescence and high pressure liquid chromatography techniques. An excitation time dependent decrease in the fluorescence intensity of its emission maximum, along with changes in the emission and ...

Comparative antiplaque activity of sanguinarine and chlorhexidine in man
Journal of Clinical Periodontology, 1990Abstract This clinical investigation examined the effect of a sanguinarine extract on bacterial plaque growth in man. Three different mouthrinses were examined: (i) Veadent® containing 0.03% sanguinarine and 0.2% zinc chloride (test rinse); (ii) a vehicle solution containing all the excipients of Veadent® except the 0.03% sanguinarine (control rinse); (

Synthesis of sanguinarine, chelerythrine, and oxysanguinarine
Collection of Czechoslovak Chemical Communications, 1984Benzo[c]phenanthridines Va and Vb have been prepared by photocyclization of amines IVa and IVb and transformed into the alkaloids sanguinarine (VIa) and chelerythrine (VIb). Oxysanguinarine (XIV) has been prepared from diazoketone XVIII.

Effect of sanguinarine on ventricular refractoriness.
Research communications in chemical pathology and pharmacology, 1980The purpose of this study was to determine the effect of the Na+K+ATPase inhibitor sanguinarine on the refractory period of the porcine ventricle. Measurements of ventricular refractoriness and strength-interval curves were obtained before and after 0.5 to 4.0 mg/kg sanguinarine.

Antimicrobial action of sanguinarine.
The Journal of clinical dentistry, 1990Sanguinarine is a benzophenanthridine alkaloid derived from rhizomes of Sanguinaria canadensis L. (bloodroot). It is a cationic molecule which converts from an iminium ion form at pH less than 6 to an alkanolamine form at pH greater than 7. Sanguinaria extract is composed of sanguinarine and five other closely related alkaloids.
