生物活性 | Allitinib tosylate (AST-1306 (TsOH)) is an orally active and irreversibleEGFRandErbB2inhibitor withIC50s of 0.5 and 3 nM, respectively. Allitinib tosylate also inhibitsErbB4with an IC50of 0.8 nM. Allitinib tosylate is an anilino-quinazoline compound and has anti-cancer activity[1] |
IC50& Target | EGFR 0.5 nM (IC50) | ErbB2 3 nM (IC50) | EGFRL858R/T790M 12 nM (IC50) | ErbB4 0.8 nM (IC50) |

体外研究 (In Vitro) | AST1306 tosylate (AST-1306 (TsOH); 0.19-6.25 μM; 72 hours) induces a significant, concentration-dependent inhibition of the growth of HIH3T3-EGFR T790M/L858R cells[1]. AST1306 tosylate inhibits the activation of tyrosine kinases and downstream signaling pathways in A549 cells, Calu-3 cells and SK-OV-3 cells. AST1306 tosylate dose-dependently and markedly inhibits EGF-induced EGFR phosphorylation in A549 cells[1]. AST1306 tosylate (0.1, 0.5, 1.0, 5.0 μM) can dramatically inhibit the growth of both tumor cells on soft agar, and SK-OV-3 cells exhibited much more sensitivity than that of A549 cells[1]. AST1306 tosylate (0.001-1.0 μM; 4 hours) is more than 3000-fold selective for ErbB family kinases over other kinase families[1]. AST1306 tosylate potently inhibits the EGFR T790M/L858R double mutant, exhibiting an IC50value of 12±2 nmol/L[1].
