task-3

CHET3 is a highly selective allosteric activator for TASK-3-containing K2P channels. CHET3 has shown potent in vivo analgesic effects in various acute and chronic pain models in rodents.

Doxapram hydrochloride hydrate (Doxapram HCl) effectively inhibits the function of TASK-1, TASK-3, and TASK-1/TASK-3 heterodimeric channels, displaying EC50 values of 410 nM, 37 μM, and 9 μM, respectively.

DCPIB, a known specific and potent inhibitor of volume-regulated anion channels (VRAC),DCPIB displayed superior selectivity toward TRESK with an IC50 of 0.14 μM, demonstrating at least 100-fold higher affinity over TREK1/TRAAK channels.

Doxapram (Dopram) is a respiratory stimulant that inhibits TASK-1, TASK-3, and TASK-1/TASK-3 heterodimer channels and is used to study ventilatory failure caused by apnea of ​​prematurity and exacerbation of chronic obstructive pulmonary disease.

PK-THPP is a channel blocker of TASK-3.

A1899 is a effective and selective TASK-1 and TASK-3 antagonist.

Pyrithiamine hydrobromide, an inhibitor of thiamine metabolism that acts as a substrate for thiamine pyrophosphate kinase, causes neurologic symptoms similar to wernickke - korsakoff syndrome in animals.

TASK-1-IN-1 is a potent and selective inhibitor of TASK-1 (Potassium Channel) with an IC50 of 148 nM, and exhibits a reduced inhibitory effect on the TASK-3 channel with an IC50 of 1750 nM. TASK-1-IN-1 also demonstrates anticancer effects.

BAY-747 (BAY 1165747) is an orally administered, brain-penetrant compound that stimulates soluble guanylate cyclase (sGC). It effectively counteracts memory impairments induced by L-NAME, improves cognitive performance in rats during the object location task (OLT), reduces blood pressure in conscious normotensive and spontaneously hypertensive rats (SHR), and enhances skeletal muscle function in the mdx/mTRG2 mouse model of Duchenne muscular dystrophy (DMD) [1] [2] [3].

NPBA, a potassium K2P channel TASK-3 (KCNK9) agonist, concurrently functions as a blocker of the tandem pore domain weak inward rectifying K+ channel (TWIK2). This compound effectively inhibits NLRP3 inflammasome activation in macrophages [1].
