A subject of the invention is a product comprising at least one Cdc25 phosphatase inhibitor in combination with at least one other anti-cancer agent for a therapeutic use which is simultaneous, separate or spread over time in the treatment of cancer. According to the invention, the other anti-cancer agent is preferably chosen from: analogues of DNA bases such as 5-fluorouracil; Type I and/or II topoisomerase inhibitors such as for example camptothecin and its analogues, doxorubicin or amsacrine; compounds interacting with the cell spindle such as for example paclitaxel (Taxol); compounds acting on the cytoskeleton such as vinblastine; inhibitors of the transduction of the signal passing through the heterotrimeric G proteins; prenyltransferase inhibitors, and in particular farnesyltransferase inhibitors; cyclin-dependent kinase (CDKs) inhibitors; alkylating agents such as cisplatin; antagonists of folic acid such as methotrexate; and inhibitors of the synthesis of DNA and cell division cell such as mitomycin C. A further subject of the invention is (1R)-1-[((2R)-2-amino-3-[(8S)-8-(cyclohexylmethyl)-2-phenyl-5,6-dihydroimidazo[1,2-a]pyrazin-7(8H)-yl]-3-oxopropyl}dithio)methyl]-2-[(8S)-8-(cyclohexylmethyl)-2-phenyl-5,6-dihydroimidazo[1,2-a]pyrazin-7(8B)-yl]-2-oxoethylamine, or a pharmaceutically acceptable salt thereof, useful as an anticancer agent.
