Sb. Singh et al., Candelalides A-C: Novel diterpenoid pyrones from fermentations of Sesquicillium candelabrum as blockers of the voltage-gated potassium channel Kv1.3, ORG LETT, 3(2), 2001, pp. 247-250
[GRAPHICS]
Blockers of the voltage gated potassium channel Kv1,3 are potential immunos
uppressants. Candelalides A-C are three novel diterpenoid pyrones that bloc
k this channel. The structure, stereochemistry, and activity against Kv1,3
are described.
