生物活性

CX1763 is an AMPAR allosteric modulator. CX1763 allosterically potentiates glutamate-evoked currents, accelerates channel opening, and increases the surface levels of AMPAR containing Glur2 (R). CX1763 enhances synaptic transmission in the rat hippocampus. CX1763 improves attention in rats and attenuates amphetamine-induced hyperactivity in mice. CX1763 can be used in studies related to attention deficit hyperactivity disorder and opioid-induced respiratory depression[1].

体外研究
(In Vitro)

CX1763 (100 μM) 是大鼠脑细胞膜和神经元中一种低影响型 AMPA 受体正变构调节剂,可增强[3H]AMPA 的结合能力以及谷氨酸诱导的峰值电流,且在浓度高达 100 μM 时无内在激动活性,同时可上调含钙离子不可渗透型 GluR2 (R)的受体[1]

体内研究
(In Vivo)

CX1763 (10 mg/kg;静脉注射;单次) 可在麻醉大鼠中诱导海马体 fEPSP 振幅产生显著且持久的约 20% 增强效应[1]
CX1763 (1-5 mg/kg;腹腔注射;单次) 在 5 mg/kg 腹腔注射剂量下,可改善大鼠 5CSRTT ADHD 模型中的特定注意力指标 (缩短反应潜伏期、减少提前反应),同时增加遗漏错误但不改变正确反应率[1]
CX1763 (1-18 mg/kg;腹腔注射;单次) 可剂量依赖性地降低苯丙胺诱导的小鼠活动亢进,其 AD50 为 2 mg/kg,腹腔注射 18 mg/kg 时可完全逆转该症状[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
