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.

Kinetin acts as plant growth accelerator, auxin, plant growth regulator, plant cell division promotor. It also acts as cell division factor found in various plant parts and in yeast. A plant growth regulator. Augments growth of microbial cultures.

Kinetin is an artificialcytokinin, obtained from herring sperm. It is named due to its ability to stimulate cell division.
Synthesis
To obtain some new analogs of kinetin we used as the starting materials 3-aryl-1-bromobutanes, which are readily available at the present time. The synthesis was carried out by the following route:
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.]
