olchemim OPTICALLY-ACTIVE DIHYDROZEATINS

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.
