Antiinflammatory Activity of Quaternary Benzophenanthridine Alkaloids fromChelidonoum majus*,**

Planta Medica, 1981
The fraction of quaternary benzophen-anthridine alkaloids from roots of CHELIDONIUM MAJUS L., containing chelerythrme and sanguinarme, has been tested for its antiinflammatory activity. On the basis of its low toxicity, high antiinflammatory activity and antimicrobial action, it is recommended for medical use in the treatment of oral inflammatory ...

Micelle assisted structural conversion with fluorescence modulation of benzophenanthridine alkaloids

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2017
In this study we have reported the anionic surfactant (Sodium dodecyl sulfate, SDS) driven structural conversion of two benzophenanthridine plant alkaloids namely Chelerythrine (herein after CHL) and Sanguinarine (herein after SANG). Both the alkaloids exist in two forms: the charged iminium and the neutral alkanolamine form. The iminium form is stable

Inhibition of liver alanine aminotransferase activity by some benzophenanthridine alkaloids

Journal of Medicinal Chemistry, 1981
The quaternary benzophenanthridine alkaloids sanguinarine (1) and chelerythrine (2) inhibit rat liver L-alanine-:2-oxoglutarate aminotransferase (EC 2.6.1.2) activity. Nitidine (3) has no inhibitory effect. The inhibitory activity of alkaloids depends on the reactivity of the iminium bond with the nucleophilic reagent, e.g., the thiol group.

Quaternary benzophenanthridine alkaloids 9,10-demethylene derivatives of sanguinarine

Chemistry of Natural Compounds, 1979
In the isolation and purification of the benzophanthridine alkaloids sanguinarine and chelerythrine two minor bases — 9,10-demethylenesanguinarine and 9,10-demethylene-9,10-dehydrosanguinarine — were isolated, and it was shown that the former is an artefact produced from sanguinarine in the process of isolation and also when the sulfates of the ...

The Benzophenanthridine Alkaloid Fagaronine Induces Erythroleukemic Cell Differentiation by Gene Activation

Planta Medica, 2005
Fagaronine, a benzophenanthridine alkaloid from Fagara zanthoxyloides Lam. (Rutaceae), has been tested on the erythroleukemic cell line K562 in order to explain some previous results on cell differentiation. In this study we showed that fagaronine induces a significant hemoglobinization of the human erythroleukemic cell line K562.
