  • n. A benzophenanthridine alkaloid extracted from the greater celandine (Chelidonium majus)

  • n. An alkaloidal principle obtained from the celandine, and named from the red color of its salts. It is a colorless crystalline substance, and acts as an acrid narcotic poison. It is identical with sanguinarine.

Etymologies

Ancient Greek celandine + red. (Wiktionary)

Examples

  • It is paramount to note that this similarity in chelerythrine binding between the two proteins would have not been discovered if it was not for the identification of the initial conserved ligand binding site between PrgI and Bcl-xL using the FAST-NMR method in combination with the CPASS database.

  • This issue may be minimized or eliminated by simply improving the PrgI binding affinity for chelerythrine derivatives.

    PLoS ONE Alerts: New Articles

  • Two compounds, chelerythrine and sanquinarine were identified as having affinity to Bcl-xL and were both available from commercial suppliers.

    PLoS ONE Alerts: New Articles

  • The didecyldimethylammonium bromide binding site (A) is found in a region responsible for needle formation while the chelerythrine binding site (B) is found on the opposite face. doi: 10.1371/journal. pone.0007442.g004

    PLoS ONE Alerts: New Articles

  • The initial identification of the conserved DDAB ligand binding site between Bcl-xL and PrgI was used to predict, test and confirm that chelerythrine binds PrgI in a similar manner to Bcl-xL.

    PLoS ONE Alerts: New Articles

  • This active-site similarity was then used to verify that chelerythrine, a known Bcl-xL inhibitor, also binds PrgI.

    PLoS ONE Alerts: New Articles

  • Verification that the Bcl-xL inhibitor chelerythrine also binds PrgI.

  • (C) The Bcl-xL region shown to bind chelerythrine is highlighted while the remaining protein structure is transparent.
