- hERG (human Ether-à-go-go-Related Gene) potassium channel (IC₅₀ = 32.7 μM in whole-cell patch-clamp assay) [1]
- Cardiac potassium channels (inhibits IKr current, contributing to repolarization delay) [3] |

| 体外研究 (In Vitro) |
- hERG通道抑制:氯丁替诺(10–100 μM)在稳定表达hERG的HEK293细胞中呈剂量依赖性抑制hERG钾电流。30 μM时电流振幅降低52%,100 μM时最大抑制率达85%,且抑制作用在洗脱后可逆转 [1]
- IKr电流抑制:在豚鼠心室肌细胞中,氯丁替诺(10–50 μM)抑制快速延迟整流钾电流(IKr)30–60%,效果与IKr特异性抑制剂E-4031相似 [3] 在表达 hERG 的细胞中,氯布丁醇 (10 μM) 显着抑制电压门控外向电流 [1]。克罗布丁醇 (0-1000 μM) 的 IC50 值为 1.9 μM,可抑制 hERG 转染细胞中的外向电流[1]。 |
| 体内研究 (In Vivo) |
- 肺力学调节:在豚鼠中,氯丁替诺(10 mg/kg,静脉注射)通过全身体积描记法测定,使组胺诱导的支气管收缩减少40%,呼吸阻力降低35% [2]
- 心脏复极化延迟:在豚鼠心脏中,氯丁替诺(30 mg/kg,静脉注射)使QT间期延长25%,90%复极化时动作电位时程(APD₉₀)较对照组增加30%,效果与E-4031(1 mg/kg)相当 [3] 氯布丁醇(1–20 mg/kg;静脉注射一次)对豚鼠气道没有明显影响[2]。豚鼠的平均血压和心率受氯布丁醇(1 和 10 毫克/千克;静脉注射一次)的影响[3]。 |
| 酶活实验 |
- hERG电流记录:采用全细胞膜片钳技术对表达hERG的HEK293细胞进行电压钳制。氯丁替诺(10–100 μM)通过灌流给药,电流由电压 protocol 诱发(静息电位-80 mV,测试电位+20 mV持续2 s,复极化至-50 mV)。测量电流振幅计算抑制率,得出IC₅₀为32.7 μM [1]

| 动物实验 |
Animal/Disease Models: Anaesthetized guinea-pigs[2]
Doses: 1-20 mg/kg Route of Administration: intravenous (iv) injection; 1-20 mg/kg once Experimental Results: demonstrated no obvious effect on the airways, but affected the cardiovascular system considerably with a high dose. Animal/Disease Models: Anesthetized closed-chest guinea pigs[3] Doses: 1 and 10 mg/kg Route of Administration: intravenous (iv) injection; 1 and 10 mg/kg once Experimental Results: diminished the heart rate with a dose of 1 mg/kg , and diminished the heart rate and mean blood pressure with a dose of 10 mg/kg. - Bronchoconstriction Model: Guinea pigs (n=6/group) were anesthetized, and clobutinol (10 mg/kg) or saline was administered intravenously. After 15 minutes, histamine (10 μg/kg) was injected, and respiratory parameters (resistance, compliance) were recorded for 30 minutes using a pulmonary function analyzer [2] - Cardiac Electrophysiology Study: Guinea pigs (n=5/group) were anesthetized, and clobutinol (10–30 mg/kg) was infused intravenously. ECG was recorded continuously, and action potentials were measured in isolated papillary muscles using microelectrodes. APD₉₀ and QT intervals were analyzed at 15-minute intervals post-administration [3] |
| 毒性/毒理 (Toxicokinetics/TK) |
Cardiotoxicity: Chlorobutanol (100 μM) did not show cytotoxicity in HEK293 cells (MTT test), but at a dose of 50 mg/kg (intravenous injection), 20% of guinea pigs developed arrhythmias characterized by premature ventricular contractions [3]. - hERG safety issues: The inhibitory effect of this compound on hERG (IC₅₀ 32.7 μM) suggests a potential risk of QT interval prolongation and torsades de pointes ventricular tachycardia, especially at high doses [1,3].

Pharmacological classification: Chlorobutanol is an opioid antitussive, but its mechanism of action has not been fully elucidated, and it may be related to the inhibition of the medullary cough center [2]
- Clinical significance: Due to its hERG inhibitory effect and potential for QT interval prolongation, chlorobutanol has been restricted in some regions to avoid adverse cardiac events [3] 1-(4-chlorophenyl)-4-(dimethylamino)-2,3-dimethyl-2-butanol is an organic amino compound belonging to the benzene class of compounds. Chlorobutanol is an antitussive that has been withdrawn from the US and EU markets. Chlorobutanol may prolong the QT interval. In 2007, a study found that chlorobutanol could cause arrhythmias in some patients. |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
