Juniperanol: First total synthesis and evaluation in Type 2 Diabetes disease

Area of Science:

• Organic chemistry
• Natural product synthesis
• Medicinal chemistry

Background:

• Juniperanol is a tricyclic sesquiterpenoid.
• It is the enantiomer of α-cedrol.
• Sesquiterpenoids are a class of terpenes derived from three isoprene units.

Purpose of the Study:

• To achieve the first total synthesis of juniperanol.
• To investigate the biological activity of juniperanol concerning glucose metabolism.

Main Methods:

• Stereoselective gold-catalyzed Ohloff-type propargylic ester rearrangement on a 10 µg scale.
• Carbocationic cascade reaction in the presence of acetyl methanesulfonate.

Main Results:

• Successful total synthesis of juniperanol was accomplished.
• The study demonstrated juniperanol's capacity to interfere with glucose processes in various cell types.

Conclusions:

• The synthesis provides a scalable route to juniperanol.
• Juniperanol exhibits potential as a modulator of cellular glucose metabolism.
