|Biological Activity or Inhibitors:||1. Perivine may resolve the instability of the retinoblastoma-associated proteins (RbAp48) complex and thus be used in Alzheimer's disease therapy.
2. Perivine, vobasine, coronaridine and dichomine show hypotensive and muscle relaxant activity.
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|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.

|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Lead discovery for Alzheimer's disease related target protein RbAp48 from traditional Chinese medicine.[Pubmed: 25165715]|
|Deficiency or loss of function of Retinoblastoma-associated proteins (RbAp48) is related with Alzheimer's disease (AD), and AD disease is associated with age-related memory loss. During normal function, RbAp48 forms a complex with the peptide FOG-1 (friend of GATA-1) and has a role in gene transcription, but an unstable complex may affect the function of RbAp48. This study utilizes the world's largest traditional Chinese medicine (TCM) database and virtual screening to provide potential compounds for RbAp48 binding. A molecular dynamics (MD) simulation was employed to understand the variations after protein-ligand interaction. FOG1 was found to exhibit low stability after RbAp48 binding; the peptide displayed significant movement from the initial docking position, a phenomenon which matched the docking results. The protein structure of the other TCM candidates was not variable during MD simulation and had a greater stable affinity for RbAp48 binding than FOG1. Our results reveal that the protein structure does not affect ligand binding, and the top three TCM candidates Bittersweet alkaloid II, Eicosandioic acid, and Perivine might resolve the instability of the RbAp48-FOG1 complex and thus be used in AD therapy.|

|Muscle relaxant activity and hypotensive activity of some Tabernaemontana alkaloids.[Pubmed: 4021514]|
|Stemmadenine, the major alkaloid from the seeds of Tabernaemontana dichotoma, showed hypotensive activity and weak muscle relaxant activity. Perivine, vobasine, coronaridine and dichomine, some of the alkaloids found in the leaves, fruits and bark of T. dichotoma, also showed hypotensive and muscle relaxant activity.|
