Eggmanone (Synonyms: EGM1) |
| Katalog-Nr.GC10796 |
Eggmanone (EGM1) ist ein potenter und selektiver Phosphodiesterase 4 (PDE4)-Antagonist mit einem IC50 von 72 nM fÜr PDE4D3. Eggmanone zeigt eine etwa 40- bis 50-fache SelektivitÄt fÜr PDE4D3 gegenÜber anderen PDEs. Eggmanone Übt seine Hh-hemmende Wirkung durch selektiven Antagonismus von PDE4 aus, was zu einer Aktivierung der Proteinkinase A und anschließender Hh-Blockade fÜhrt.

Eggmanone is a potent and selective PDE4D3 inhibitor with IC50 value of 72 nM that antagonizes the Hedgehog signaling pathway [1].
Hedgehog (Hh) signaling plays an important role in vertebrate development, and its dysregulation is a driver of numerous malignancies. Phosphodiesterase 4 (PDE4) is a target for Hh inhibition. Eggmanone exerts its Hh-inhibitory effects through selective antagonism of PDE4, leading to protein kinase A activation and subsequent Hh blockade [1].
Eggmanone is a potent and selective PDE4 inhibitor that antagonizes the Hedgehog signaling pathway. In Sufu-/- mouse embryonic fibroblasts (MEFs), Eggmanone significantly reduced transcription levels of Gli1 and Ptc1. Eggmanone functioned upstream of Gli processing and nuclear translocation to exert its Hh-inhibitory effects. Eggmanone exhibited potent antagonism of PDE4D3 with IC50 value of 0.072 μM, approximately 40- to 50-fold selective over PDE3A, PDE10A2, and PDE11A4 (IC50s = 3, 3.05, and 4.08 μM, respectively). In Shh-Light2 cells transfected with PDE4D3, Eggmanone restored the increased Hh signaling [1].
