Biological Activity of AST-1306

DescriptionAST1306 is a selective, irreversible EGFR and ErbB2 inhibitor with IC50s of 0.5 and 3 nM, respectively.In Vitro:AST1306 induces a significant, concentration-dependent inhibition of the growth of HIH3T3-EGFR T790M/L858R cells. In addition, AST1306 effectively inhibits EGFR phosphorylation in HIH3T3-EGFR T790M/L858R cells. AST1306 inhibits the growth of NCI-H1975 cells that harbor the EGFR T790M/L858R mutation in a concentration-dependent manner, and blocks phosphorylation of EGFR and downstream pathways as well. AST1306 inhibits the phosphorylation of EGFR and ErbB2, and downstream signaling in human cancer cells. AST1306 inhibits the proliferation of human cancer cells, with ErbB2-overexpressing cells exhibiting more sensitivity[1].In Vivo:AST1306 potently suppresses tumor growth in ErbB2-overexpressing adenocarcinoma xenograft and FVB-2/Nneu transgenic breast cancer mouse models, but weakly inhibits the growth of EGFR-overexpressing tumor xenografts. Tumor growth inhibition induced by a single dose of AST1306 in the SK-OV-3 xenograft model is accompanied by a rapid (within 2 h) and sustained (≥24 h) inhibition of both EGFR and ErbB2, consistent with an irreversible inhibition mechanism[1].

Protocol

Cell Assay [1]
Cells are seeded into 96-well plates and grown for 24 h. The cells are then treated with increasing concentrations of AST1306 and grown for a further 72 h. Cell proliferation is evaluated using the SRB (Sulforhodamine B) assay[1].

Animal Administration [1]
Mice: Mice are administered AST1306 at dosage of 100, 50 and 25 mg/kg twice daily and treated with lapatinib (50 mg/kg) as comparison. Tumors are measured twice a week in two dimensions, using a caliper, and the tumor volume is calculated according to the formula L×W×W/2[1].

Background on AST-1306

AST1306 is a novel inhibitor of EGFR and HER2 (IC50 = 0.5 nM and 3 nM respectively)

EGFR (epidermal growth factor receptor) is a cell-surface receptor tyrosine kinase. The receptor activation leads to dimerization and tyrosine autophosphorylation. It induces a cascade of downstream cellular responses such as modification in gene expression, cell proliferation and cytoskeletal rearrangement etc. HER2 is a member of the epidermal growth factor and is associated with breast and ovarian cancers.

AST1306 selectively blocked EGFR and HER2 kinase activities in a cell-free assay. The tyrosine kinase activity of EGFR mutant T790M/L858R was also inhibited by AST1306 in intact cell and cell-free assays. In addition, AST1306 attenuated the EGFR and HER2 phosphorylation and downstream substrates. [1]

In ErbB2-overexpressing xenograft and FVB-2/Nneu transgenic mouse model, AST1306 potently inhibited tumor growth. In SK-OV-3 xenograft model, AST1306 caused a quick and long-lasting (≥24h) inhibition of EGFR and HER2. [1]

miR-551b regulates epithelial-mesenchymal transition and metastasis of gastric cancer by inhibiting ERBB4 expression.[Pubmed:28501849]

Oncotarget. 2017 Jul 11;8(28):45725-45735.

Epithelial-mesenchymal transition (EMT) is an important biological process that is characteristic of malignant tumor cells with metastatic potential. We investigated the role of miR-551b in EMT and metastasis in gastric cancer (GC). We found that low miR-551b levels were associated with EMT, metastasis and a poor prognosis in GC patients. Further, two GC cell lines, MNK45 and SGC7901, exhibited lower miR-551b levels than the GES normal stomach cell line. Exposing MNK45 and SGC7901 cells to TGF-beta1 resulted in cell morphology changes characteristic of EMT, which was confirmed by Western blot analysis demonstrating low E-Cadherin and high N-Cadherin and Vimentin levels. Treatment with miR-551b mimics inhibited these EMT changes as well as Transwell migration and invasiveness. We identified ERBB4 as a potential target of miR-551b based on patient data from the TCGA. ERBB4 was upregulated in GC specimens, and its high expression correlated with a poor prognosis of GC patients. Dual luciferase assays revealed that miR-551b directly inhibited ERBB4 by binding to its 3'UTR. Moreover, treatment with miR-551b mimics or the ERBB4 inhibitor AST-1306 inhibited EMT in the GC cell lines. Finally, nude mice xenografted with GC cancer cell lines expressing miR-551b mimics exhibited smaller tumors and longer survival than mice engrafted with control GC cancer cells. These data indicate that miR-551b inhibits EMT and metastasis in GC by inhibiting ERBB4. miR-551b and ERBB4 are thus potential therapeutic targets for the treatment of GC.
