3β-Hydroxy-5β-cholest-7-en-6-one as an Intermediate of 20-Hydroxyecdysone Biosynthesis in a Hairy Root Culture of Ajuga reptans var. atropurpurea

Article abstract of DOI:10.1039/c39940001761

<3α-2H>-, <4α-2H>- and <4β-2H>-Cholesterols and <3α-2H>- and <5-2H>-3β-hydroxy-5β-cholest-7-en-6-ones were converted with a hairy root culture of Ajuga reptans var. atropurpurea into 20-hydroxyecdysone, in which the deuterium atoms retained their original positions, thus strongly suggesting that 3β-hydroxy-5β-cholest-7-en-6-one is an obligatory intermediate in the biosynthesis of ecdysteroids in the plant.
