Kinetin Chemical Properties,Usage,Production

Description

Kinetin (or Vivakin) was introduced as Kinerase in the US as a new ingredient for the treatment of age related photodamage of skin. This 6- furfurylaminopurine is a synthetic cytokinin, a family of plant growth factors, and was shown to be a highly potent growth factor. In vitro, it was able to delay or prevent the onset of age-related changes in skin cells without affecting cellular lifespan. In a double-blind clinical trial, Kinetin (0.005%) partially reversed the clinical signs of photodamaged skin and demonstrated a good safety profile. It could have potential in psoriasis as well as in other proliferative skin disorders.

Description

Kinetin is a cytokinin plant growth regulator with diverse biological activities. Kinetin (0.23 μM) increases p34^cdc2-like histone H1 kinase activity, the number of cells in mitosis, and total cell number in arrested N. plumbaginifolia cells. It increases GSH levels and activity of glutathione peroxidase and glutathione reductase, but reduces thiobarbituric acid reactive substances (TBARS) levels, in human skin fibroblasts when used at a concentration of 10 μM. Kinetin (40 μM) reduces age-related enlargement, multinucleation, and accumulation of cellular debris in human mammary skin fibroblasts without affecting proliferative lifespan.

Definition

ChEBI: Kinetin is a member of the class of 6-aminopurines that is adenine carrying a (furan-2-ylmethyl) substituent at the exocyclic amino group. It has a role as a geroprotector and a cytokinin. It is a member of furans and a member of 6-aminopurines.

General Description

Kinetin is an artificial?cytokinin, obtained from herring sperm. It is named due to its ability to stimulate cell division.

Biochem/physiol Actions

FAPα has in vitro dipeptidyl peptidase activity and collagenolytic activity. It cleaves N-terminal dipeptides from polypeptides and can degrade gelatin and type I collagen. It has also been reported that FAPa has a tumor suppressor activity.

Purification Methods

It forms platelets from EtOH and sublimes at 220o, but is best done at lower temperatures in a good vacuum. It has been extracted from neutral aqueous solutions with Et2O. [Miller et al J Am Chem Soc 78 1375 1956, Bullock et al. J Am Chem Soc 78 3693 1956, Beilstein 26 III/IV 3586.]
