Description | Cercosporamide is a ATP-competitive Pkc1 kinase inhibitor (IC50 <50 nM; Ki <7 nM). It also is a unique Mnk inhibitor. |
In vitro | Cercosporamide is a broad-spectrum natural antifungal compound and a selective and highly potent fungal Pkc1 kinase inhibitor [1]. Cercosporamide is recently shown to act as a unique Mnk inhibitor with antileukemic properties. Cercosporamide is a potent inhibitor of phosphorylation of eIF4E at Ser209 in AML cells and results in potent inhibitory effects on primitive leukemic progenitors (CFU-L) from AML patients. When U937 cells are incubated in the presence or absence of the increasing doses of Cercosporamide, dose-dependent suppression of cell growth is found. Similar experiments with comparable results are seen when the effects of Cercosporamide on MM6 and K562 cells are examined [2]. |
In vivo | Treatment with either Cercosporamide or Ara-C alone markedly inhibits xenograft growth compared to their respective controls, achieving statistical significance (P<0.011 for 10 mg/kg Cercosporamide twice-daily; P<0.006 for 20 mg/kg Cercosporamide daily; P<0.0374 for Ara-C). The combined application of Cercosporamide (10 mg/kg twice daily) with Ara-C substantially enhances efficacy beyond that of either compound used singly. Similarly, the synergy of Cercosporamide (20 mg/kg daily) with Ara-C markedly reduces tumor growth compared to both captisol (P<0.0001) and water controls (P=0.0003), albeit without significant superiority over the individual effects of either Cercosporamide (20 mg/kg) or Ara-C alone. |
