Manumycin A from Streptomyces parvulus has been used to inhibit I?B kinase (IKK)b?nuclear ?-B essential modulator (NEMO) interaction in the homogeneous time-resolved fluorescence (HTRF)-based binding assay.
Biochem/physiol Actions
Potent inhibitor of Ras farnesyltransferase.
Manumycin A is a natural monomeric epoxyquinoid. It has an ability to inhibit tumor necrosis factor (TNF) induced I?B kinase (IKK) activity in various cell types. In addition, manumycin A exhibits anti-tumor property by inhibiting farnesylation of oncogenic Ras.
