| Hazard Information | Back Directory | [Uses]
PK-THPP is a potent TWIK-related acid-sensitive K(+) ion channel (TASK-3 ion channel) blocker (IC50s are 35 nM and 300 nM for TASK-3 and TASK-1, respectively)[1]. PK-THPP increases breathing rate and induces respiratory alkalosis in rats[2]. | [Biochem/physiol Actions]
PK-THPP is a potent antagonist of tandem pore potassium channel subunit TASK-3 (KCNK9, K2P9.1) with an IC50 value of 35 nM for TASK-3 compared to 303 nM for TASK-1 and with >140 fold selectivity over a wider range of potassium channels. PK-THPP was found to act as a respiratory stimulant, stimulating breathing in isoflurane-anesthetized rats. | [storage]
