General description

Paxilline is an indole diterpene metabolite produced by fungi. It has a functionalized pentacyclic core and is a template for the synthesis of a wide variety of derivatives.

Application

Paxilline has been used to block large conductance calcium activated potassium channels (BKCa) in murine smooth muscle cells and in myometrial cells of uterine samples. Paxilline acts as an agonist and activates liver X receptor in atlantic salmon.

Biochem/physiol Actions

Paxilline is a selective blocker of high-conductance Ca2+-activated (Maxi-K) potassium channels. It also blocks big potassium (BK) channels.

Using a monoclonal antibody based ELISA, 600 pAN7-1 plasmid-tagged mutants of Penicillium paxilli were screened for paxilline accumulation and one paxilline-negative mutant, YI-20, was identified. A molecular analysis of this mutant showed that pAN7-1 was inserted at a single site
