Opticallyactive 6-alkynyl- and 6-alkylpurines have been synthesized. These compounds can be regarded as analogs of cytokinin plant growth hormones. The analogs were examined as growth stimulators and as inhibitors of 15-lipoxygenase (15-LO). The (S)-enantiomer of 6-(5-hydroxy-4-methylpent-1-yl)purine exhibited profound growth stimulation activity, especially at low concentrations. 6-(Hydroxyalkyn-1-yl)purines
