A simple, sensitive and accurate method for the separation and determination of the naphthoquinones, deoxyshikonin (I), acetylshikonin (II) and beta-beta-dimethylacrylshikonin (III) in tissue cultured Zicao is described. The sample solution was applied at a point 1 cm from the bottom edge of the TLC silica gel plate (10 x 15 cm). A mixture of n-hexane-acetone-chloroform-glacial acetic acid (13:0.3:0.2:0.05 v/v) was used as the developing solvent. The plate was saturated for 30 min and then…

Cellular pharmacology studies of shikonin derivatives
It is hypothesized that shikonin is an effective inhibitor of protein–protein interaction with multiple targets in both the intracellular and extracellular compartments, which can account for the broad spectrum of shik onin biological and pharmacological activities.
The inhibition of N-acetyltransferase activity and gene expression in human bladder cancer cells (T24) by shikonin.
Shikonin should be considered as a candidate agent for the prevention or treatment of transitional cell carcinoma and decreased the amount of AAF production and AF-DNA adducts formation in human 724 cells in all examined AF doses.
