|Biological Activity or Inhibitors:||1. Cornin induces angiogenesis in vitro via a programmed PI3K/Akt/eNOS/VEGF signaling axis.
2. Cornin has protective potential against cerebral ischemia injury and its protective effects may be due to amelioration of cerebral mitochondrial function and its antioxidant property.
3. Cornin has antimitotic action on dividing cell.
4. Cornin has cardioprotection against experimental myocardial ischemic injury due to an increase in expression of phospho-CREB and phospho-Akt.

|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Cornin induces angiogenesis through PI3K-Akt-eNOS-VEGF signaling pathway.[Pubmed: 23702325]|
|In the present study, we sought to elucidate whether Cornin contributes to induce angiogenesis and its mechanisms. To this end, we examined the role of Cornin on human brain microvascular endothelial cell line (HBMEC) proliferation, invasion, and tube formation in in vitro. For study of mechanism, the phosphoinositide 3 kinase (PI3K)-Akt inhibitor LY294002, endothelial nitric oxide synthase (eNOS) inhibitor L-NAME, vascular endothelial growth factor (VEGF) antagonist sFlt-1 and VEGF receptor blocker SU-1498 were used. HMBEC proliferation was tested by MTT. Scratch adhesion test was used to assess the ability of invasion. A matrigel tube formation assay was performed to test capillary tube formation ability. PI3K-Akt-eNOS-VEGF pathway activation in HMBEC was tested by Western blot. Our data suggested that Cornin induces angiogenesis in vitro by increasing proliferation, invasion and tube formation. VEGF expression was increasing by Cornin and counteracted by VEGF antagonist sFlt-1, LY294002 and L-NAME in HMBEC. Tube formation was increased by Cornin and counteracted by VEGF receptor blocker-SU1498, LY294002 and L-NAME. It may be suggested that Cornin induces angiogenesis in vitro via a programmed PI3K/Akt/eNOS/VEGF signaling axis.|

|Cornin ameliorates cerebral infarction in rats by antioxidant action and stabilization of mitochondrial function.[Pubmed: 20041427]|
|This study was conducted to investigate the efficacy of Cornin, an iridoid glycoside, in an experimental cerebral ischemia induced by middle cerebral artery occlusion (MCAO) and reperfusion (I/R), and to elucidate the potential mechanism. Adult male Sprague-Dawley rats were subjected to MCAO for 1 h, then reperfusion for 23 h. Behavioral tests were used to evaluate the damage to central nervous system. The results showed that Cornin significantly decreased neurological deficit scores, and reduced cerebral infarct volume and degenerative neurons. Meanwhile, Cornin significantly increased the brain ATP content, improved mitochondrial energy metabolism, inhibited the elevation of MDA content and ROS generation, and attenuated the decrease of SOD and GPx activities in brain mitochondria. These findings indicate that Cornin has protective potential against cerebral ischemia injury and its protective effects may be due to amelioration of cerebral mitochondrial function and its antioxidant property.|

|Purification and some characteristics of liver cytosol cornin, an antimitotic substance from rat liver cytosol.[Pubmed: 144419]|
|Further purification and characterization are reported on rat cytosol Cornin (RLCC), an antimitotic substance. Fraction I (purified RLCC) was purified more than 10-fold from crude Cornin with Sephadex G-50 column chromatography and showed a remarkable inhibitory effect on division of inseminated sea urchin eggs and mouse fibroblast cells.|

|Cardioprotection against experimental myocardial ischemic injury using cornin.[Pubmed: 26871971 ]|
|Phosphorylated-cyclic adenosine monophosphate response element-binding protein (Phospho-CREB) has an important role in the pathogenesis of myocardial ischemia. We isolated the iridoid glycoside Cornin from the fruit of Verbena officinalis L, investigated its effects against myocardial ischemia and reperfusion (I/R) injury in vivo, and elucidated its potential mechanism in vitro. Effects of Cornin on cell viability, as well as expression of phospho-CREB and phospho-Akt in hypoxic H9c2 cells in vitro, and myocardial I/R injury in vivo, were investigated. Cornin attenuated hypoxia-induced cytotoxicity significantly in H9c2 cells in a concentration-dependent manner. Treatment of H9c2 cells with Cornin (10 μM) blocked the reduction of expression of phospho-CREB and phospho-Akt in a hypoxic condition. Treatment of rats with Cornin (30 mg/kg, iv) protected them from myocardial I/R injury as indicated by a decrease in infarct volume, improvement in hemodynamics, and reduction of severity of myocardial damage. Cornin treatment also attenuated the reduction of expression of phospho-CREB and phospho-Akt in ischemic myocardial tissue. These data suggest that Cornin exerts protective effects due to an increase in expression of phospho-CREB and phospho-Akt.|
