N6-(델타2-이소펜테닐)-아데닌

개요A purine alkaloid, this base was first isolated from the leaves of Gleditsia triacanthus L., and subsequently discovered in Chidlowia sanguinea and Holar_x0002_rhena floribunda (G. Don.) Dur. et Schinz. The free alkaloid forms colourless crystals and yields crystalline salts and derivatives, e.g. the hydrochloride, m.p. 218-9°C; hydrobromide, m.p. 215-6°C; sulphate, two salts are formed with m.p. 175-6°C and 216-7°C respectively depending upon the amount of acid used in their preparation; picrate, m.p. 246-7°C (dec.); picrolonate, m.p. 229-231 0 C; methiodide, m.p. 227-9°C and the N-benzyl derivative, m.p. 150°C. Oxidation of the alkaloid with KMn04 gives 7-(2:3-dihydroxy-3-methylbutyl)-6-aminopurine which, on periodate oxidation, furnishes 7-(formylmethyl)- 6-aminopurine and Me2CO. Heating the base with Ba(OHh gives one mole each of NH3, C02 and 4-N-(r:r-dimethylallyl)-N-amino-imidazole-5-carboxamide.

용도N6-(2-Isopentenyl)adenine can be used in biological study for cytokinins stimulated expression of stress-related proteins and transcripts in Arabidopsis thaliana with isopentenyltransferase overexpression.
