Lawsone (aka hennatannic acid) is a red-orange dye present in the leaves of the henna plant as well as the flower of water hyacinth. Henna extracts have been used by humans as hair and skin dyes for more than 5000 years. Henna extracts have been clinically investigated as a method of reducing dose-limiting Chemotherapy-Induced Palmoplantar Erythrodysesthesia.

Sample Use Guides

In Vivo Use Guide

In a mouse skin carcinogen model, mice that were fed lawsone (0.0025%) for 10 weeks decreased tumor incidence by 72% and multiplicity by 50%. The trend continued throughout the 20 week testing period.

Route of Administration: Oral

In Vitro Use Guide

Lawsone was investigated for growth inhibitory activity against a panel of 6 human cancer cell lines exhibiting different levels of resistance to pro-apoptotic stimuli using the MTT colorimetric assay; including U373, A549, Hs683, SKMEL-28, PC3, LoVo. Lawsone demonstrated IC50 values of 58 microM against A549 cells and 31 microM against Hs683 cells. The IC50 values for other cell lines were reported as > 100 microM.
