摘要：Recently, a new compound IT-M-07000 was designed as a prodrug of tamibarotene, one of the therapeutic agents for acute promyelocytic leukemia. In the present study, IT-M-07000 was administered to mice to investigate whether it is actually metabolized to tamibarotene. Its metabolic pathway and the utility as a tamibarotene prodrug were also evaluated. After oral administration of IT-M-07000, IT-M-07000, tamibarotene and two compounds that were supposed to be metabolic intermediates in a β-oxidation pathway of IT-M-07000 to tamibarotene were detected in mouse plasma. It was thus shown that IT-M-07000 is probably β-oxidized to tamibarotene in mice. Comparison of tamibarotene concentration profiles after oral administration of IT-M-07000 or tamibarotene showed that the plasma tamibarotene concentration increased slower and was retained stable, and the area under the plasma concentration–time curve ( AUC ) of tamibarotene was larger in mice administered IT-M-07000 than tamibarotene. These results indicate that IT-M-07000 is possibly useful as a prodrug of tamibarotene.
