The present invention relates to the field of oligopeptide prodrugs that are intended for the treatment of cancer. The selectivity of these prodrugs requires the presence of an (oligo)peptidic moiety and/or a protective capping group to ensure the prodrug stability in blood. It further in particular relates to the exemplary oligopeptidic moiety ALGP and to prodrugs comprising it. In particular it also relates to the capping group phosphonoacetyl and to prodrugs comprising this capping group.

cleaved the L enantiomer of MTX but left the D enantiomer unaffected. The 2-desamino and 2-desamino-2-methyl analogues of AMT and MTX inhibited the growth of tumorcells, but were very poor inhibitors of dihydrofolatereductase (DHFR). These unexpected results suggested that activity in intact cells was due to metabolism of the 2-desamino compounds to polyglutamates.
