TAS-121是一款第三代、高选择性、共价结合的口服EGFR-酪氨酸激酶抑制剂(EGFR-TKI).该化合物在多种EGFR突变体中表现出强效,包括L858R突变(IC50=1.7 nM)、Ex19del突变(IC50=2.7 nM)、L858R/T790M双重突变(IC50=0.56 nM)以及Ex19del/T790M双重突变(IC50=1.1 nM);同时对野生型EGFR的抑制作用也显著(IC50=8.2 nM).此外,TAS-121对HER2和HER4的抑制作用IC50值分别为110 nM和2.6 nM.该抑制剂能够阻断EGFR及其下游信号通路的磷酸化,从而抑制癌细胞增殖并诱导细胞凋亡.在包括SW48 (EGFR G719S)和NCI-H1975 (EGFR L858R/T790M)在内的异种移植模型中,TAS-121展现了其抗肿瘤活性.

产品描述 | TAS-121 is an orally active, selective, covalent third-generation mutant EGFR tyrosine kinase inhibitor (EGFR-TKI). It effectively inhibits the L858R mutation (IC50=1.7 nM), Ex19del mutation (IC50=2.7 nM), L858R/T790M mutation (IC50=0.56 nM), and Ex19del/T790M mutation (IC50=1.1 nM), as well as wild-type EGFR (IC50=8.2 nM). TAS-121 also inhibits HER2 and HER4 with an IC50 of 110 nM and 2.6 nM, respectively. This compound prevents cellular proliferation by inhibiting the phosphorylation of EGFR and its downstream signaling targets, thereby inducing apoptosis. Additionally, TAS-121 demonstrates antitumor activity in xenograft models such as SW48 (EGFR G719S) and NCI-H1975 (EGFR L858R/T790M). |
