生物活性

Colivelin TFA is a brain penetrant neuroprotective peptide and a potent activator of STAT3, suppresses neuronal death by activating STAT3 in vitro. Colivelin TFA exhibits long-term beneficial effects against neurotoxicity, Aβ deposition, neuronal apoptosis, and synaptic plasticity deficits in neurodegenerative disease. Colivelin TFA has the potential for the treatment of alzheimer's disease and ischemic brain injury.

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 Ca/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.

Western Blot Analysis

Cell Line:	BV-2 cells.
Concentration:	50 µg/mL.
Incubation Time:	4 hours.
Result:	Increased p-STAT3 levels.

Cell Viability Assay

Cell Line:	KYSE70 and TE8 cells.
Concentration:	0.5 μM.
Incubation Time:	1 hour (followed by CYT-Rx20 treatment)
Result:	Significantly suppressed the viability in KYSE70 and TE8 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.

Animal Model:	CD-1 mice
Dosage:	10 pmol/3 μl
Administration:	Intracerebroventricular administration
Result:	Completely suppressed Aβ 25-35-mediated impairment in spatial working memory and increased the number of immunoreactive neurons.

Animal Model:	C57 mice
Dosage:	1.4, 7, or 35 nM/0.21mL
Administration:	Intraperitoneal administration
Result:	Protected against cholinotoxin-induced amnesia in mice.

Animal Model:	Male C57BL/6 mice
Dosage:	1 mg/kg
Administration:	Intraperitoneal administration
Result:	Protected against ischemic brain injury, and improves neurological outcomes.
