Some imidazopyrimidines structurally analogous to the corresponding natural kinetics (adenine, benzyladenine, kinetic) were prepared and tested for cytokinin-like activity. Among the compounds tested for ability to retard degradation of the photosynthetic system, the 7-chloroderivatives (II-III) showed activity comparable with that of natural kinetic and confirm the chlorine function as a potentiator of biological activity.
