产品详情
(S)-Willardiine是AMPA/kainate受体有效激动剂,EC50值为44.8uM。
生物活性
(S)-Willardiine is a potent agonist of AMPA/kainate receptors with EC50 of 44.8 uM. IC50 value: 44.8 uM(EC50) [1] Target: AMPA/kainate receptor agonist in vitro: The (S)- but not (R)-isomers of willardiine and 5-bromowillardiine were potent agonists, producing rapidly but incompletely desensitizing responses [1]. At a concentration of 1.8 mM, Ca2+ inhibited the currents induced by 100 microM willardiine by approximately 50% [2]. in vivo: In newborn mice (P5, histopathology at P10), local injection of the AMPA receptor agonist S-bromo-willardiine at day 5 after birth induced cortical damage and white matter damage, which was reduced in a dose-dependent manner by the AMPA receptor antagonists [3].

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
