QUICK LINKS

Paxilline is an indole alkaloid isolated from Penicillium paxilli. Paxilline may act to selectively and reversibly block the high conductance Ca2+-activated K+ channel. In neutrophils, Paxilline blockage of Maxi-K channels decreased the alkalinization of phagocytic vacuoles and inhibited the microbicidal process. When paxilline was applied to the smooth muscle of the rat vas deferens at more positive potentials than -40 mV up to 15 mV, significant depolarization of the smooth muscle contractions was observed. Paxilline is an inhibitor of MaxiKalpha, IP3R and SERCA.
