What is Olivetol CAS 500-66-3

Olivetol CAS 500-66-3, also known as 5-pentylresorcinol or 5-pentyl-1,3-benzenediol, is a naturally occurring organic compound found in certain species of lichen and can be readily extracted; it is also produced by a number of insects, either as a pheromone, repellent, or antiseptic. Olivetol is also a precursor in various syntheses of tetrahydrocannabinol.

How to biosynthesize Olivetol?

Olivetol is biosynthesized by a polyketide synthase (PKS)-type reaction from hexanoyl-CoA and three molecules of malonyl-CoA by an aldol condensation of a tetraketide intermediate. In 2009, Taura et al. were able to clone a type III PKS named olivetol synthase (OLS) from Cannabis sativa. This PKS is a homodimeric protein that consists of a 385 amino acid polypeptide with a molecular mass of 42,585 Da that has high sequence similarity (60-70%) identity to plant PKS’s.

The data from Taura’s study of OLS’s enzyme kinetics show that OLS catalyzes a decarboxylative-aldol condensation to produce olivetol. This is similar to stilbene synthase’s (STS) mechanism for converting p-coumaroyl-CoA and malonyl-CoA to resveratrol. Although olivetol is the decarboxylated form of OLA, it is highly unlikely that OLS produces olivetol from OLA.[10][11] Crude enzyme extracts prepared from flowers and leaves did not synthesize olivetolic acid, but only yielded olivetol.[10] The exact mechanism of olivetol biosynthesis is as yet unsure, but it is possible that an OLA-forming metabolic complex forms along with OLS.[10] In addition, it also appears that OLS only specifically accepts starter CoA esters with C4 to C8 aliphatic side chains such as hexanoyl-CoA.
