McMillan L, Carr R, Young C, Astin J, Lowe R, Parker E, et al.
Mol Genet Genomics . 2003 Jul; 270(1):9-23. PMID: 12884010
The gene cluster required for paxilline biosynthesis in Penicillium paxilli contains two cytochrome P450 monooxygenase genes, paxP and paxQ. The primary sequences of both proteins are very similar to those...

FEBS Lett . 2002 Sep; 527(1-3):298-302. PMID: 12220678
Iberiotoxin (IbTX) is a remarkably selective alpha-K toxin peptide (alpha-KTx) inhibitor of the maxi-K channel. In contrast, the highly homologous charybdotoxin inhibits both the maxi-K and K(V)1.3 channels with similar...

Biochemistry . 2001 Sep; 40(39):11687-97. PMID: 11570869
Correolide is a novel immunosuppressant that inhibits the voltage-gated potassium channel K(v)1.3 [Felix et al. (1999) Biochemistry 38, 4922-4930]. [(3)H]Dihydrocorreolide (diTC) binds with high affinity to membranes expressing homotetrameric K(v)1.3...

J Biol Chem . 1999 Aug; 274(36):25237-44. PMID: 10464244
Correolide, a novel nortriterpene natural product, potently inhibits the voltage-gated potassium channel, K(v)1.3, and [(3)H]dihydrocorreolide (diTC) binds with high affinity (K(d) approximately 10 nM) to membranes from Chinese hamster ovary...

Felix J, Bugianesi R, Schmalhofer W, Borris R, Goetz M, Hensens O, et al.
Biochemistry . 1999 Apr; 38(16):4922-30. PMID: 10213593
A novel nortriterpene, termed correolide, purified from the tree Spachea correae, inhibits Kv1.3, a Shaker-type delayed rectifier potassium channel present in human T lymphocytes. Correolide inhibits 86Rb+ efflux through Kv1.3...
