The therapeutic potential of A2-32-01 was further illustratedin its cytotoxicity against primary leukemic cells expressinghigh levels of HsClpP(Table 1). Importantly, the drug hadnegligible effects on the viability of normal primaryhematopoietic cells (Table 1), which illustrates specifictargeting of cancer cells over normal ones. Furthermore, usinga xenografted immunodeficient mouse model, A2-32-01 wasshown to suppress the proliferation of OCI-AML2 and primaryhuman leukemic cells in vivo, with no observable toxic side effects on the animals
