Abstract

Abstract A series of 3-substituted xanthines, 2-(2-hydroxy-2-methylpropylamino)-9-methyl-6- benzylaminopurine and 7-benzylaminooxazolo [5, 4-d] pyrimidine were synthesized as potential inhibitors of cytokinin N-glucosylation. In maize leaf segments the latter compound was found to be the most effective inhibitor tested, inhibiting the formation of the 9-glucoside of 6-benzylaminopurine (BAP) and raising the amount of free BAP. N-glucosylation of BAP ...
