Prodrugs activated predominantly or exclusively in inflammatory tissue, more particularly prodrugs of methotrexate and derivatives thereof, which are selectively activated by Reactive Oxygen Species (ROS) in inflammatory tissues associated with cancer and inflammatory diseases, as well as method for preparing said prodrugs.

antagonists methotrexate and 10-ethyl-10-deazaaminopterin are oxidized in vivo to their 7-hydroxy derivatives. A specific cyanation at the C-7 position of the pteridine ring system using diethyl phosphorocyanidate converted the dimethyl esters of methotrexate and 10-ethyl-10-deazaaminopterin to the corresponding 7-cyano dimethyl ester derivatives, which were hydrolyzed to the 7-hydroxymetabolites.
