Candelalides A-C: novel diterpenoid pyrones from fermentations of Sesquicillium candelabrum as blockers of the voltage-gated potassium channel Kv1.3

Org Lett. 2001 Jan 25;3(2):247-50. doi: 10.1021/ol006891x.

Abstract

[figure: see text] Blockers of the voltage-gated potassium channel Kv1.3 are potential immunosuppressants. Candelalides A-C are three novel diterpenoid pyrones that block this channel. The structure, stereochemistry, and activity against Kv1.3 are described.
