Shikonin (SKN), a highly liposoluble naphthoquinone pigment isolated from the roots of Lithospermum erythrorhizon, is known to exert antibacterial, wound-healing, anti-inflammatory, antithrombotic, and antitumor effects. The aim of this study was to examine SKN antibacterial activity against methicillin-resistant Staphylococcus...

Accumulation of alkaloids in plant vacuoles does not involve an ion-trap mechanism.

Planta

Deus-Neumann B, Zenk MH.
PMID: 24241730
Planta. 1986 Jan;167(1):44-53. doi: 10.1007/BF00446367.

Alkaloid uptake into vacuoles isolated from a Fumaria capreolata L. cell suspension culture was investigated. The uptake is carrier-mediated as shown by its substrate saturation, its sensitivity to metabolic inhibitors and especially by its exclusive preference for the (S)-forms...
