产品详情
LML134 (化合物 18b) 是一种具有口服活性,高选择性 H3R (组胺 3 受体) 反向激动剂,对 hH3R 的 cAMP 和 bdg 的 Kis 分别为 0.3 nM 和 12 nM。LML134 快速穿透大脑,导致高 H3R 占有率,并以快速的动力学特征使其目标脱离。LML134 有用于过度睡眠障碍的潜力。
生物活性
LML134 (compound 18b) is an orally active and high selective Histamine 3 receptor (H3R) inverse agonist with K i s of 0.3 nM and 12 nM for hH3R cAMP and hH3R bdg. LML134 penetrates the brain rapidly, leading to high H3R occupancy, and disengages its target with a fast kinetic profile. LML134 has the potential for excessive sleep disorders.

体内研究(In Vivo)
LML134 (compound 18b) (oral; 10 mg/kg) indicates rapid oral absorption, with a T max of 0.5 hours, t 1/2 of 1.54 hours and a fraction absorbed of 44%, as well as a rapid clearance in male Sprague-Dawley rats.
LML134 (i.v.; 1 mg/kg) has t 1/2 of 0.44 hours, CL of 28 mL/min/kg and the low plasma protein binding in male Sprague-Dawley rat (Fu =39.0%).
has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
