개요
trans-Zeatin is a cytokinin plant growth regulator with antioxidant and neuroprotective activities. It binds to the cytokinin receptor Arabidopsis histidine kinase 3 (AHK3) with a KD value of 1.3 nM. trans-Zeatin increases chlorophyll levels in etiolated Cucumus sativus cotyledons in a concentration-dependent manner. It increases callus growth and shoot formation in N. tabacum calluses when used at concentrations of 5 and 50 μM. trans-Zeatin (25-100 μM) reduces production of reactive oxygen species (ROS) induced by amyloid β (25-35) (Aβ25-35) in PC12 cells. It reduces scopolamine-induced spontaneous alternations in the Y-maze, indicating enhanced spatial memory, in mice when administered at doses of 1.5, 3, and 4.5 mg/kg per day.화학적 성질
white to light yellow crystal powder물리적 성질
Trans-zeatin is freely soluble in acetic acid and water.정의
Increased levels of cytokinins such as trans-zeatin, which are considered highly active, induced resistance against mainly (hemi)biotrophic pathogens in different plant species. In contrast, cis-zeatin is commonly regarded as a cytokinin exhibiting low or no activity [1].정의
ChEBI: The trans-isomer of zeatin.일반 설명
trans-Zeatin contains a hydroxylated isoprenoid side chain.Purification Methods
Purify zeatin by recrystallisation from EtOH or H2O. The UV has max at 207 and 275nm ( 1,400 and 14,650) in 0.1N aqueous HCl; 212 and 270nm ( 17,050 and 16,150) in aqueous buffer pH 7.2; 220 and 276nm ( 15,900 and 14,650) in 0.1N aqueous NaOH. The picrate has m 192-194o (from H2O) from which zeatin can be recovered by treatment with Dowex-1 x 8 (200-400 mesh, OH-form). [Letham et al. Aust J Chem 22 205 1969, Proc Chem Soc (London) 230 1964, Shaw & Wilson Proc Chem Soc (London) 231 1964.] It is a cell division factor (plant growth regulator) [Letham & Palni Ann Rev Plant Physiol 34 163 1983] and inhibits mitochondrial function [Miller Plant Physiol 69 1274 1982]. The commercially available trans -9-riboside derivative, [6025-53-2], M 351.4,is a cytokine which separates from aqueous AcOH with m 177-179o. It solubility in AcOH is ~5%.
