task-3

Doxapram hydrochloride hydrate (Doxapram HCl) 是 TASK-1，TASK-3和 TASK-1 TASK-3异二聚体通道的抑制剂，EC50分别为410 nM，37 μM 和9 μM。

CHET3 是一种含 TASK-3 的 K2P 通道的高度选择性变构激活剂。CHET3 在啮齿动物的各种急性和慢性疼痛模型中显示出强大的体内镇痛作用。

Doxapram (Dopram) 是一种呼吸兴奋剂，抑制 TASK-1，TASK-3 和 TASK-1 TASK-3 异二聚体通道，可用于研究早产儿呼吸暂停和慢性阻塞性肺疾病恶化引起的通气衰竭。

DCPIB 是选择性可逆体积调节性阴离子通道抑制剂，抑制肿胀激活氯电流，在 CPAE 细胞中，IC50值为 4.1 μM。它能够电压依赖性激活钾离子通道 TREK1 和 TRAAK，抑制 TRESK、TASK1 和 TASK3的 IC50值分别为 0.14、0.95 和 50.72 μM。

TASK-1-IN-1 是一种有效的选择性的 TASK-1 (Potassium Channel) 抑制剂（IC50 ： 148 nM）。TASK-1-IN-1 对 TASK-3 通道 的IC50 为 1750 nM，抑制作用有所降低。TASK-1-IN-1 具有抗癌作用。

BAY-747 (BAY 1165747) 为一种通过口服生效且具有脑渗透性的sGC刺激剂。它能可逆地逆转L-NAME所诱导的记忆障碍并在大鼠中增强认知功能。BAY-747还可在有意识状态下降低正常血压及自发性高血压大鼠(SHR)的血压。此外，BAY-747在mdx mTRG2小鼠模型中改善了与Duchenne肌营养不良症(DMD)相关的骨骼肌功能。

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

NPBA为K2P通道TASK-3 (KCNK9)的激动剂，并对串联孔域弱内向整流K+通道(TWIK2)具有阻断作用。此外，NPBA能够抑制巨噬细胞中NLRP3炎性体的激活。

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

Pyrithiamine is the pyridine analog of thiamine that prevents growth of organisms that require intact thiamine. [1] It inhibits the growth of bacterial and fungal species at a pyrithiamine:thiamine ratio of 10:1 in growth media and induces symptoms of thiamine deficiency in mice at a dietary ratio of 3:1. These effects are reversible with addition of sufficient thiamine in all species. Pyrithiamine inhibits the formation of cocarboxylase from thiamine in chicken blood in a dose-dependent manner. [2] It has been used to induce thiamine deficiency in various disease models, including rat models of alcoholism and diencephalic amnesia, to study the effects of thiamine deficiency on disease pathology.[3] [4] Reference：[1].
