Description

General description

Carnosol (CAR) is an ortho-diphenolic diterpene, extracted from the Mediterranean dietary herb Rosmarinus officinalis L. (rosemary). It was first isolated from the Salvia carnosa (Sage) plant. Carnosol is also a pro-electrophilic molecule.

Application

Carnosol has been used as an anti-cancer agent:

• to test its anti-cancer and anti-proliferative activities on cancer stem-like cells (CSCs) and Glioblastoma multiforme (GBM) cells
• to inspect its anti-carcinogenic effects on nineteen genes involved in up-and down-regulation of different genetic carcinogenesis pathways and on HeLa cells in human cervical cancer model
• as a reference standard to identify and quantify the metabolites of rosemary extract using liquid chromatography coupled to tandem mass spectrometry (LC/ESI-MS/MS)

Biochem/physiol Actions

A phenolic diterpene with antioxidant and anticarcinogenic activities.

Carnosol together with carnosic acid (CA) accounts for 90% of the antioxidant activity of rosemary leaves. It exerts neuroprotective properties and protects against neuroinflammation, and oxidative stress-induced brain damage under chronic stress conditions. Carnosol is a strong chemo-therapeutic agent studied for several types of cancer like breast, leukemia, skin, prostate, and colon. It is also an antimicrobial agent.
