  • Patent number: 4659825
    Abstract: This invention relates to isomeric O-phosphonylmethyl derivatives of the formula I ##STR1## wherein R.sup.5 designates an adenin-9-yl moiety, R.sup.4 are alternately a hydrogen atom and a --CH.sub.2 P(O)(OH).sub.2 group, and the configuration at the carbon atom in the position 2 is S, R or RS.The compounds according to the invention are biologically active as inhibitors of metabolic processes and in organism they are stable towards enzymes, cleaving phosphomonoester bonds.The said compounds exhibit also chemosterilizing action on insects.
