In Candida albicans, farnesol is a sesquiterpene alcohol that alters intercellular communication. Inhibitory activities of the compound against bacteria, Paracoccidioides brasiliensis, and non-albicans Candida species have also been demonstrated. FARNESOL was evaluated in the concentration range of 0.29-150 μM, and the minimum inhibitory concentration (MIC) was established in accordance with the M27-A3 procedure as stated. The study revealed that farnesol had inhibitory activity (MIC range: 0.29-75.0 μM) against Cryptococcus gattii and Neoformans. While farnesol does not significantly change phospholipase activity, there is a tendency for its activity to decline [1].

Metabolism / Metabolites
Farnesol is metabolized to farnesyl glucuronide, hydroxyfarnesol and hydroxyfarnesyl glucuronide by human tissue microsomes. ... Farnesol metabolism was examined by a sensitive LC (liquid chromatography)-MS/MS method. Results indicate that farnesol is a good substrate for glucuronidation in human liver, kidney and intestine microsomes (values in nmol/min per mg). Initial analysis using expressed human UGTs indicated that UGTs 1A1 and 2B7 were primarily responsible for glucuronidation in vitro, with significantly lower activity for all the other UGTs tested (UGTs 1A3, 1A4, 1A6, 1A9 and 2B4). Kinetic analysis and inhibition experiments indicate that, in liver microsomes, UGT1A1 is primarily responsible for farnesol glucuronidation; however, in intestine microsomes, UGT2B7 is probably the major isoform involved, with a very-low-micromolar K(m). ...
Farnesol has known human metabolites that include (2S,3S,4S,5R)-3,4,5-Trihydroxy-6-(3,7,11-trimethyldodeca-2,6,10-trienoxy)oxane-2-carboxylic acid.

Farnesol is a colorless liquid with a delicate floral odor. (NTP, 1992)
A colorless liquid extracted from oils of plants such as citronella, neroli, cyclamen, and tuberose. It is an intermediate step in the biological synthesis of cholesterol from mevalonic acid in vertebrates. It has a delicate odor and is used in perfumery. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed)
Farnesol has been reported in Aristolochia triangularis, Humulus lupulus, and other organisms with data available.

Mechanism of Action
... the effect of 20 uM farnesol on the distribution of protein kinase C (PKC) between cytosolic and membrane fractions of HeLa S3K cells and fibroblasts line CF-3 was examined. In HeLa cells farnesol caused translocation of PKC from membrane fraction to cytosol after 1h of incubation and also prevented PMA-stimulated induction of PKC translocation from cytosol to membranes. Up to 6 h of incubation, there was no effect of farnesol on PKC localization in CF-3 fibroblasts. The results point to possible involvement of PKC in the toxic effect of farnesol ...
... in MCF-7 human breast cancer cells, farnesol induced the expression of thyroid hormone receptor (THR) beta1 mRNA and protein at concentrations that inhibited cell growth. Changes in the expression of THR responsive genes, however, suggested that farnesol inhibits THR-mediated signaling. Protein extracts from cells treated with farnesol displayed decreased binding to oligodeoxynucleotides containing a consensus sequence for the THR response element, despite the higher THRbeta1 content, providing a mechanism to explain the decreased transcriptional activity of cellular THRs.
Farnesol-mediated apoptosis was prevented by transformation with a plasmid coding for the phosphatidic acid (PA) phosphatase LPP3, but not by an inactive LPP3 point mutant. Farnesol did not directly inhibit LPP3 PA phosphatase enzyme activity in an in vitro mixed micelle assay. ...
