EPO and anemia (phenotype): The anti‐anemia efficacy of 17 was then investigated in cisplatin‐induced anemia mice; Figure 5E, the hemoglobin (Hb) levels of 17‐treated mice were increased in a dose‐dependent manner by po administered 17, indicating that 17 can upregulate EPO and stimulate erythropoiesis production, in a manner useful for the treatment of anemia (Figure 5F).
