Application

Cafestol acetate has been used to determine the effects of coffee on heat shock response (HSR).

Biochem/physiol Actions

Cafestol is a coffee-specific diterpene. It has anti-carcinogenic and anti-inflammatory activities. Cafestol stimulates apoptosis in cells associated with colorectal and renal cancer (Caki cells). It is used to study mechanisms of anti-oxidation related to hydrogen peroxide induced oxidative stress and DNA damage. Cafestol increases the level of glutathione (GSH), by stimulating γ-glutamylcysteine synthetase. It acts as a chemopreventive agent by inducing cytochrome P-450.

Other Notes

Coffee consumption is worldwide spread with few side effects. Interestingly, coffee intake has been inversely related to the serum enzyme activities gamma-glutamyltransferase, and alanine aminotransferase in studies performed in various countries. In addition, epidemiological results, taken together, indicate that coffee

Coffee is a popular beverage worldwide with various nutritional benefits. Diterpene cafestol, one of the major components of coffee, contributes to its beneficial effects through various biological activities such as chemopreventive, antitumorigenic, hepatoprotective, antioxidative and antiinflammatory effects. In this study

There is an increasing evidence that oxidative stress is implicated in the processes of inflammation and carcinogenesis. It has been shown that kahweol and cafestol, coffee-specific diterpenes, exhibit chemoprotective effects. This study investigated the effects of kahweol and cafestol, coffee-specific

Epidemiological studies have found an inverse association between coffee consumption and the risk of liver cancer. Animal data support such a chemopreventive effect of coffee. Substantial research has been devoted to the identification of coffee components that may be responsible
