产品描述：

Colivelin TFA 是一种具有大脑通透性的神经保护肽 (neuroprotective peptide)，是 STAT3 的有效激活剂。Coliveli 通过激活 STAT3 在体外抑制神经元死亡。Colivelin TFA 对神经毒性、Aβ 沉积,神经元细胞凋亡，在神经退行性疾病显示出长期有利的影响。Colivelin TFA 可用于阿尔茨海默病和缺血性脑损伤的相关研究。

体外研究:

Colivelin completely suppresses death induced by overexpressed FAD-causative genes and Aβ1-43 at a concentration of 100 fm, and keep its neuroprotective action at or above the levels of 1 nm.

Colivelin-induced neuroprotection occurs via two neuroprotective pathways: one mediated by Ca2+/calmodulin-dependent protein kinase IV, triggered by ADNF, and one mediated by signal transducer and activator of transcription 3, triggered by HN.
Colivelin reverses caspase3, Bax and Bcl-2 expressions in HT22 cells medaited by rmMFG-E8 in the co-cultured cells under OGD condition.
Colivelin (50 µg/mL, 4 hours) significantly increases the p-STAT3 protein levels in BV-2 cells.

体内研究:

Colivelin(intracerebroventricular administration; 10 pmol/3 μl; 3 weeks) suppresses impairment in spatial working memory induced by repetitive intracerebroventricular injection of Aβ25-35 or Aβ1-42, in addition, it antagonizes neuronal loss in the CA1 region of hippocampus induced by hippocampal injection of Aβ1-42.

Colivelin (intraperitoneal administration; 1.4, 7, or 35 nM/0.21mL; on the Y-maze testday) suppresses memory impairment caused by 3-quinuclidinyl benzilateand restricts functional memory deficit.

Colivelin (intraperitoneal injection; 1 mg/kg; 14 days) results in improved motor and cognitive function with time by performance of mNSS, rotarod, and corner turning test.It also reduces lesion volume and improves neurological deficits after MCAO
