In vitro antifungal activity and possible mechanisms of action of chelerythrine

Pesticide Biochemistry and Physiology, 2020
Chelerythrine (CHE) possesses broad pharmacological activities. In this study, the extract of Chelidonium majus L. were characterized by high performance liquid chromatography (HPLC), infrared radiation (IR) spectroscopy and nuclear magnetic resonance (NMR). It was proved that the extract was CHE.

Selective inhibition of monoamine oxidase A by chelerythrine, an isoquinoline alkaloid

Bioorganic and Medicinal Chemistry Letters, 2018
Chelerythrine, an isoquinoline alkaloid isolated from the herbaceous perennial Chelidonium majus, was found to potently and selectively inhibit an isoform of recombinant human monoamine oxidase-A (MAO-A) with an IC50 value of 0.55 µM. Chelerythrine was a reversible competitive MAO-A inhibitor (Ki = 0.22 µM) with a potency much greater than toloxatone ...

Chelerythrine is a potent and specific inhibitor of protein kinase C

Biochemical and Biophysical Research Communications, 1990
The benzophenanthridine alkaloid chelerythrine is a potent, selective antagonist of the Ca++/phospholopid-dependent protein kinase (Protein kinase C: PKC) from the rat brain. Half-maximal inhibition of the kinase occurs at 0.66 microM. Chelerythrine interacted with the catalytic domain of PKC, was a competitive inhibitor with respect to the phosphate ...

Structural modification of sanguinarine and chelerythrine and their antibacterial activity

Natural Product Research, 2011
In this study, five derivatives of sanguinarine (1) and chelerythrine (2) were prepared, with 1 and 2 as starting materials, by reduction, oxidation and nucleophilic addition to the iminium bond C=N+. The structures of all compounds were elucidated on account of their MS, ¹H-NMR and ¹³C-NMR data.
