• To facilitate the structural elucidation of moxestrol's metabolic products across species.

Main Methods:

• Isolation of compounds from the bile of phenobarbital-pretreated rats.
• Enzymatic hydroxylation using microorganisms to generate specific metabolites.
• Chemical synthesis of selected reference compounds.
• Structural determination using comprehensive physical and chemical analytical techniques.

Main Results:

• A series of reference compounds, crucial for moxestrol metabolite identification, were successfully obtained.
• The structures of all synthesized and isolated compounds were rigorously confirmed.

Conclusions:

• The prepared reference compounds provide essential tools for the accurate identification of moxestrol metabolites.
• This work supports further research into the metabolic fate and pharmacokinetic profile of moxestrol.
