4 Pharmacology and Biochemistry
4.1 Absorption, Distribution and Excretion

Long-chain alcohols have been detected in lipid extracts of bovine and porcine brain and heart muscle at levels of approximately 0.002% (w/w) of the total lipids. Hexadecanol, octadecanol, octadecenol and, in the bovine tissues, docosanol were identified as major constituents.

Takahashi, T, Schmid, HHO; Chem Physics of Lipids 4 (2): 243-246 (1970)


Long chain alcohols were detected in developing rat brain at highest level of 0.0109% of the total lipids at the age of 10 days and decreased to 0.0036% at the age of 40 days. They consisted mainly of hexadecanol, octadecanol, octadecenol, eicosanol, docosanol, and tetracosanol.

PMID:834119 Natarajan V, Schmid HH; Lipids 12 (1): 128-30 (1977)


A mixture of cis-9[1(-14)C] octadecenol and [1(-14)C] docosanol was injected into the brains of 19-day-old rats, and incorporation of radioactivity into brain lipids was determined after 3, 12, and 24 hr. Both alcohols were metabolized by the brain but at different rates; each was oxidized to the corresponding fatty acid, but oleic acid was more readily incorporated into polar lipids. Substantial amounts of radioactivity were incorporated into 18:1 alkyl and alk-1-enyl moieties of the ethanolamine phosphoglycerides and into 18:1 alkyl moieties of the choline phosphoglycerides. Even after the disappearance of the 18:1 alcohol from the substrate mixture (12 hr), the 22:0 alcohol was not used to any measurable extent for alkyl and alk-1-enylglycerol formation.

The distribution of radioactivity from intravenously administered cis-9[1-14C]octadecenol into various tissues of the rat was studied as a function of time. The pattern of incorporation of radioactivity into alkyl, alk-1-enyl and acyl moieties of the lipids in heart, lungs, liver, intestine, kidney, brain and plasma revealed that oxidation of the long-chain alcohol and esterification of the resulting fatty acid to a wide variety of lipids are by far the most predominant reactions. Acylation of the long-chain alcohol is observed especially in liver, which appears to be the major site of biosynthesis of wax esters. Alkylation of the long-chain alcohol to alkoxylipids occurs in most tissues, most predominantly in the heart.

4.2 Metabolism/Metabolites

cis-9-Octadecenyl alcohol (oleyl alcohol), orally administered, increased the relative concentration of 18:1 alkyl and alk-1-enyl moieties in alkoxylipids of the small intestine of rats.

Bandi ZL et al; Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism 239 (3): 357-367 (1971)


A mixture of cis-9[1(-14)C] octadecenol and [1(-14)C] docosanol was injected into the brains of 19-day-old rats, Both alcohols were metabolized by the brain but at different rates; each was oxidized to the corresponding fatty acid, but oleic acid was more readily incorporated into polar lipids. Substantial amounts of radioactivity were incorporated into 18:1 alkyl and alk-1-enyl moieties of the ethanolamine phosphoglycerides and into 18:1 alkyl moieties of the choline phosphoglycerides.

PMID:916829 Natarajan V, Schmid HH; Lipids 12 (10): 872-5 (1977)


cis-9-[1-(14)C]Octadecenol, cis,cis-9,12-[1-(14)C]octadecadienol, and cis,cis,cis-9,12,15-[1-(14)C]octadecatrienol were administered intracerebrally to 18-day-old rats. Incorporation of radioactivity into the constituent alkyl, alk-1-enyl, and acyl moieties of the ethanolamine phosphatides of brain was determined after 3, 6, 24, and 48 hr. Incorporation of radioactivity from each precursor proceeded at approximately the same rate leading to mono-, di-, and triunsaturated alkyl and alk-1-enyl glycerols. In addition, the labeled alcohols were found to be oxidized to the corresponding fatty acids which were incorporated into acyl groups; radioactivity derived from di- and triunsaturated alcohols was found mainly in acyl moieties produced through chain elongation and desaturation reactions of di- and triunsaturated fatty acids.

4.3 Mechanism of Action

Farnesol (FOH) inhibits the CDP-choline pathway for PtdCho (phosphatidylcholine) synthesis, an activity that is involved in subsequent induction of apoptosis /SRP: programmed cell death/. Interestingly, the rate-limiting enzyme in this pathway, CCTalpha (CTP:phosphocholine cytidylyltransferase alpha), is rapidly activated, cleaved by caspases and exported from the nucleus during FOH-induced apoptosis. The purpose of the present study was to determine how CCTalpha activity and PtdCho synthesis contributed to induction of apoptosis by FOH and oleyl alcohol. Contrary to previous reports, /the authors/ show that the initial effect of FOH and oleyl alcohol was a rapid (10-30 min) and transient activation of PtdCho synthesis. During this period, the mass of DAG (diacylglycerol) decreased by 40%, indicating that subsequent CDP-choline accumulation and inhibition of PtdCho synthesis could be due to substrate depletion. At later time points (>1 h), FOH and oleyl alcohol promoted caspase cleavage and nuclear export of CCTalpha, which was prevented by treatment with oleate or DiC8 (dioctanoylglycerol). Protection from FOH-induced apoptosis required CCTalpha activity and PtdCho synthesis since (i) DiC8 and oleate restored PtdCho synthesis, but not endogenous DAG levels, and (ii) partial resistance was conferred by stable overexpression of CCTalpha and increased PtdCho synthesis in CCTalpha-deficient MT58 cells. These results show that DAG depletion by FOH or oleyl alcohol could be involved in inhibition of PtdCho synthesis. However, decreased DAG was not sufficient to induce apoptosis provided nuclear CCTalpha and PtdCho syntheses were sustained.
