Olechemin 二氢玉米素系列植物标品
二氢玉米素(Dihydrozeatin)首次从未成熟的羽扇豆(Lupinus luteus)籽提取所得,研究发现其在某些生物反应中比另两种天然的细胞分裂素反式玉米素和N6-异戊烯腺嘌呤活性更弱。(R)-和(S)-异构体两种对映体之间的细胞分裂活性也有差异。非天然的(R)-(+)-构型通常比天然存在的(S)-(-)-二氢玉米素显示出更高的细胞分裂活性。 Dihydrozeatin has been isolated for the first time from immature seeds of Lupinus luteus. It was revealed to be less active than two other natural cytokinins trans-zeatin and N6-isopentenyladenine in several bioassays. Different cytokinin activity between enantiomers of (R)- and (S)-configurations is also known. The unnatural (R)-(+)-antipode always showed higher cytokinin activity than naturally occurring (S)-(-)-dihydrozeatin. Different R)-(+)- and (S)-(-)-dihydrozeatins are also produced by OlChemIm Ltd.
