Abstract
Primitive or progenitor hematologic cancer cells have been implicated in the early stages and development of leukemia and malignant lymphoproliferative disorders, including acute myelogenous leukemia (AML), chronic myelogenous leuke mia (CML) and chronic lymphoid leukemia (CLL). Interleu kin-3 receptor alpha chain (IL-3Ra or CD123) is strongly expressed on progenitor hematologic cancer cells, but is vir tually undetectable on normal bone marrow cells. The present invention provides methods of impairing progenitor hemato logic cancer (e.g., leukemia and lymphomic) cells by selec tively targeting cells expressing CD123. These methods are useful in the detection and treatment of leukemias and malig nant lymphoproliferative disorders. Also provided are com pounds useful for selectively binding to CD123 and impairing progenitor hematologic cancer cells. These compounds may include cytotoxic moieties such as, for example, radioiso topes or chemotherapeutics.
