Background:

Penitrem A is an indole diterpene neurotoxic alkaloid produced by Penicillium, acts as a selective BK channel antagonist with antiproliferative and anti-invasive activities against multiple malignancies. Penitrem A increases the spontaneous release of endogenous glutamate, gamma-aminobutyric acid (GABA) and aspartate from cerebrocortical synaptosomes, and induces tremorgenic syndromes in animals[1][2].
