Cafestol


Cafestol is a diterpenoid molecule present in coffee beans. It is one of the compounds that may be responsible for proposed biological and pharmacological effects of coffee.

Research into biological activity

Coffee consumption has been associated with a number of effects on health and cafestol has been proposed to produce these through a number of biological actions. Studies have shown that regular consumption of boiled coffee increases serum cholesterol whereas filtered coffee does not. Cafestol may act as an agonist ligand for the nuclear receptor farnesoid X receptor and pregnane X receptor, blocking cholesterol homeostasis. Thus cafestol can increase cholesterol synthesis.
Cafestol has also shown anticarcinogenic properties in rats.
Cafestol also has neuroprotective effects in a Drosophila fruit fly model of Parkinson's disease.
