Abstract: A method of inhibiting the growth of leukemic hematopoietic stem cells in a subject with leukemia is described. The method includes administering a therapeutically effective amount of a composition including a compound of formula I: I wherein R1 is independently selected from hydrogen and methyl; R2 is selected from the group consisting of 4,8-dimethyl-non-1-enyl, 4,8-dimethyl-nonyl, non-1-enyl, and nonanyl groups; X is a carboxyl, phosphonic, or sulfonic moiety, and n is an integer from 1 to 6, or a compound of Formula II: II wherein R1 is a C6-C12 alkyl or C6-C12 alkoxy group; R2 is independently selected from the group consisting of hydrogen, methoxy, and hydroxyl; and R3 is an alkyl or cycloalkyl group; or a pharmaceutically acceptable salt thereof.

Abstract: The invention provides for methods of treating a mammal who has a BCR/ABL-mediated leukemia, including chronic myelogenous leukemia (CML), particularly the blast crisis stage of CML, Philadelphia-positive acute lymphoblastic leukemia (Ph?-ALL), and refractory leukemias. The invention also provides for compounds for the treatment of these leukemias and methods of identifying anti-leukemic agents.

Abstract: Methods—for treatment and prevention of lymphoid malignancies, including, but not limited to acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), B-cell lymphoma, Acute Myeloid leukemia (AML), and mantle cell lymphoma (MCL). The methods include administration of a therapeutically effective amount of FTY720 (2-Amino-2-[2-(4-octylphenyl)ethyl]propane 1,3-diol hydrochloride) or a derivative, pharmaceutically acceptable salt thereof, or a prodrug thereof to a subject.
