An object is to provide a novel therapeutic drug for adult T-cell leukemia having an ATL cell specific antitumor effect. The therapeutic drug for adult T-cell leukemia according to the invention is characterized by containing a compound represented by the formula I or a prodrug thereof, wherein R1 is H, OH, an alkoxy group, an acyl group, or a thioacyl group, R2 is an acyl group, a thioacyl group, CONR7R8, or CSNR7R8 (R7 and R8 being each independently H, an alkyl group containing 1 to 3 carbon atoms, or a phenyl group), or R1 and R2 together may form a ring, X1 and X2 may be the same or different and are each —CR3R4—, —SiR3R4— or oxygen, and R3 and R4 may be the same or different and are each an alkyl group containing 1 to 6 carbon atoms.

Adult T cell leukemia (ATL), caused by infection of human T-lymphotropic virus type 1 (HTLV-1), has a poor prognosis and curative therapy is unavailable, so it is important to find or design superior lead compounds for the drug treatment of ATL. We used our micro-reversed fragment-based drug design hypothesis and multi-template hypothesis to extract the tetrahydrotetramethylnaphthalene (TMN) skeleton from tamibarotene, a useful medicament for the treatment of acute promyelocytic leukemia (APL). Structural development of TMN yielded highly ATL cell-selective growth inhibitors, including 2-acetyl-3-hydroxy-5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene (6). Structure-activity relationship analysis suggests the existence of a specific target molecule for ATL cell-selective inhibition of proliferation through G2 arrest.
