Application

Cercosporamide from Cercosporidium henningsii has been used as a mitogen-activated protein (MAP) kinase-interacting kinase (MNK) inhibitor in glioblastoma (GBM)-derived BS287 spheres. It has also been used as an inhibitor of bone morphogenetic protein receptor (BMPR) type I kinase in HepG2 cells and zebrafish embryos in particular to test its rescue potential against developmental defects.

Biochem/physiol Actions

Cercosporamide was initially identified as a phytotoxin with broad-spectrum anti-fungal activity. Studies have shown that cercosporamide is a specific, highly potent fungal inhibitor of the cell wall integrity-signaling pathway mediator, protein kinase (Pkc1) inhibitor. Semisynthetic cercosporamide analogues demonstrated hypoglycemic activity and therefore, serve as candidates for potential new anti diabetic drugs. Cercosporamide was found to block eIF4E (Eukaryotic Initiation Factor) phosphorylation in cultured cancer cells, inducing apoptosis, suppressing proliferation, and reducing soft agar colonization. Its eIF4E phosphorylation inhibitory effect was also shown when administrated orally on xenograft human tissue and mouse liver tissue. Cercosporamide is a potent and selective Mnk inhibitor. It reduces tumor growth in xenografted HCT116 tumor and suppresses the outgrowth of B16 melanoma lung metastases. Hence, blocking Mnk function and eIF4E phosphorylation may be an attractive anticancer strategy.

Preparation Note

Through bioassay-guided fractionation, the EtOAc extract of a culture broth of the endophytic fungus Phoma species ZJWCF006 in Arisaema erubescens afforded a new α-tetralone derivative, (3S)-3,6,7-trihydroxy-α-tetralone (1), together with cercosporamide (2), β-sitosterol (3), and trichodermin (4).

Peroxisome proliferator-activated receptor γ (PPARγ; NR1C3) is known as a key regulator of adipocytogenesis and the molecular target of thiazolidinediones (TZDs), also known as antidiabetic agents. Despite the clinical benefits of TZDs, their use is often associated with adverse effects

In an investigation of (-)-Cercosporamide derivatives with a plasma glucose-lowering effect, we found that N-benzylcarboxamide derivative 4 was a partial agonist of PPARgamma. A SAR study of the substituents on carboxamide nitrogen afforded the N-(1-naphthyl)methylcarboxamide derivative 23 as the most

Selective peroxisome proliferator-activated receptor gamma (PPARγ) modulators are expected to be a novel class of drugs improving plasma glucose levels without PPARγ-related adverse effects. As a continuation of our studies for (-)-Cercosporamide derivatives as selective PPARγ modulators, we synthesized substituted

Peroxisome proliferator-activated receptor gamma (PPARγ) is a potential drug target for treating type 2 diabetes. The selective PPARγ modulators (SPPARMs), which partially activate the PPARγ transcriptional activity, are considered to improve the plasma glucose level with attenuated PPARγ related adverse
