Kinetin — 45 years on

Plant Science, 1999
Abstract Kinetin (N 6 -furfuryladenine) was the first cytokinin to be isolated almost 45 years ago from DNA as an artifactual rearrangement product of the autoclaving process. Since then its chemical structure and properties have been well described. Most importantly, a wide variety of biological effects of kinetin, including those on gene expression,

Effects of Radiation on Kinetin Solutions

Nature, 1967
When the plant hormone kinetin is X-irradiated it decomposes to an extent depending on the exposure. Ultra-violet spectrophotometry and chromatography indicate that the chief degradation compounds are adenine, hypoxanthine and a substance with an R of 0.28.

N⁶-Furfuryladenine (kinetin) hydrochloride

Acta Crystallographica Section C Crystal Structure Communications, 2002
In the title compound, N(6)-furfuryladenin-3-ium chloride, C(10)H(10)N(5)O(+).Cl(-), the adenine moiety exists as the N3-protonated N7-H tautomer. The orientation of the N6 substituent (furfuryl moiety) is distal to the imidazole ring of the adenine base.

Kinetin and Kinetin-Like Compounds

1963
Plant physiologists for many years have sought to learn the chemical nature of compounds which strongly promote cell division. These compounds have been detected in numerous plant extracts such as those from coconuts, maize endosperm, banana and horsechestnut fruits, carrot and tobacco leaves, grapes, crown gall tumours, female gametophytes of Ginkgo ...

Chloroplasts, Kinetin and Protein Synthesis

Physiologia Plantarum, 1971
AbstractThe effect of kinetin on protein synthesis of isolated chloroplasts was investigated by following the incorporation of 14C‐leucine into isolated chloroplasts from Nicotiana tabacum. The incorporation activity varied greatly during the year, being largest in the winter and smallest in the summer. Conversely, the relative effect of kinetin on the

Oxidation of kinetin by mammalian xanthine oxidase

Biochimica et Biophysica Acta, 1958
Abstract Kinetin is oxidized by mammalian xanthine oxidase to 2,8-dihydroxykinetin, 8-hydroxykinetin being the intermediate. The furfuryl side-chain is not removed during these reactions. The enzymic rate of kinetin exceeds that of adenine.

Biological Activities of Kinetin

2008
Kinetin (N6-furfuryladenine) is a cytokinin growth factor with several biological effects observed for human cells and fruit flies. It was given the name kinetin because of its ability to induce cell division. Kinetin is often used in plant cell and tissue culture for induction of callus formation (in conjunction with auxin) and to regenerate shoots ...

Auxin and Kinetin Interaction in Apical Dominance

Science, 1966
The effects of auxin on the inhibition of lateral buds in decapitated bean plants are enhanced if kinetin is applied together with auxin. The uptake of 14 C-indoleacetic acid by the stumps of decapitated plants is increased in the presence of kinetin and leads to extensive transport of 14 C ...

Karyokinetic interference in Triturus following kinetin treatment

Experimental Cell Research, 1966
Abstract Adult newts, Triturks viridescens , were exposed to kinetin for periods of 4 to 21 days. Mitotic Index of the intestinal nest cells of kinetin treated newts was about 8–15 times higher than the controls and in the liver capsule cells, about 8 times higher than the controls.

Identification of 6-Furfuryladenine (Kinetin) in Human Urine

Biochemical and Biophysical Research Communications, 2000
In contrast to the current view of kinetin (K, N(6)-furfuryladenine) as an unnatural and synthetic cytokinin, recently it has been identified in plant DNA and plant extract. Here we describe identification of K in human urine using chromatography/mass-spectrometry analysis for the first time. The amount of kinetin in urine taken from unhealthy patients
