Hypothemycin inhibits eosinophilic EOL1 cell carrying mutations in FIP1L1-PDGFRα, acute myeloid leukemia MV-4-11 cell carrying mutations in FLT3-ITD, and melanoma COLO829 cell carrying mutations in BRAF V600E. It has an IC50s of 0.4 nM, 6 nM, and 50 nM, respectively. Hypothemycin also inhibits HUVEC cell carrying mutations in VEGFR, mastocytoma P815 cell carrying mutations in c-KIT D814Y, NSCLC A459 cell carrying mutations in KRAS, and ovarian SKOV-3 cell carrying mutations in HER2 (IC50s: 70 nM, 370 nM, 6.0 μM, and 7.0 μM, respectively)[2].

Hypothemycin (10 mg/kg) kills T. brucei in infected mice. However, it completely curing the infection in one third of animals, although high doses of Hypothemycin (>10 mg/kg) leads to side effects.
