525-79-1 Usage
Description
Different sources of media describe the Description of 525-79-1 differently. You can refer to the following data:
1. 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.
2. Kinetin is a cytokinin plant growth regulator with diverse biological activities. Kinetin (0.23 μM) increases p34cdc2-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.

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.]
Check Digit Verification of cas no
The CAS Registry Mumber 525-79-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,2 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 525-79:
(5*5)+(4*2)+(3*5)+(2*7)+(1*9)=71
71 % 10 = 1
So 525-79-1 is a valid CAS Registry Number.

Efficient Phosphorus-Free Chlorination of Hydroxy Aza-Arenes and Their Application in One-Pot Pharmaceutical Synthesis
Wang, Jian,Li, Yan-Hui,Pan, Song-Cheng,Li, Ming-Fang,Du, Wenting,Yin, Hong,Li, Jing-Hua
, p. 146 - 153 (2020/03/10)
The chlorination of hydroxy aza-arenes with bis(trichloromethyl) carbonate (BTC) and SOCl2 has been effectively performed by refluxing with 5 wt % 4-dimethylaminopyridine (DMAP) as a catalyst. Various substrates are chlorinated with high yields. The obtained chlorinated aza-arenes can be used directly with simple workup for succedent one-pot synthesis on a large scale.
Synthetic method for high-purity 6-furfurylaminopurine
-
Paragraph 0012-0014, (2018/12/14)
The invention discloses a synthetic method for high-purity 6-furfurylaminopurine. According to the synthetic method, in the existence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), furfuryl amine and 6-chloropurine are subjected to nucleophilic substitution reaction under reflux condition of hexamethyldisilazane so as to obtain a crude product of 6-furfurylaminopurine, and recrystallizing is carriedout so as to obtain 6-furfurylaminopurine, the HPLC purity is 99.5% or above, and the any individual impurity content is less than 0. 1wt%. The synthetic method has the advantages of being simple inprocess, high in yield and free of wastewater discharge.

-
Paragraph 0045; 0046, (2017/07/19)
The invention discloses a method for synthesizing adenine and derivatives thereof. The method comprises the steps: firstly, subjecting diethyl malonate and dimethyl dioxirane to an oxidation reaction, so as to obtain 2-hydroxyldiethyl malonate; then, carrying out an ammonolysis reaction with ammonia water, so as to obtain 2-hydroxyl malonamide; then, carrying out a cyclization reaction with trimethyl orthoformate, so as to obtain 5-hydroxyl pyrimid-4,6-(1H,5H)-dione; then, carrying out a chlorination reaction with phosgene, so as to obtain 4,5,6-trichloropyrimidine; then, carrying out a cyclization reaction with formamidine hydrochloride, so as to obtain 4-chloro-1H-pyrazol[3, 4-d]pyrimidine; finally, carrying out an ammoniation reaction with ammonia water or an amine compound in the presence of triethylamine, thereby obtaining the adenine and derivatives thereof.
