JBJ-09-063 hydrochloride 是一种突变选择性变构 EGFR 抑制剂，对 EGFR L858R、EGFR L858R/T790M、EGFR L858R/T790M/C797S 和 EGFRLT/L747S 的 IC50 分别为 0.147 nM、0.063 nM、0.083 nM 和 0.396 nM。JBJ-09-063 hydrochloride 有效降低 EGFR、Akt 和 ERK1/2 磷酸化。JBJ-09-063 hydrochloride 对 EGFR 酪氨酸激酶抑制剂
JBJ-09-063 hydrochloride is a mutant-selective allosteric EGFR inhibitor with IC50s of 0.147 nM, 0.063 nM, 0.083 nM and 0.396 nM for EGFR L858R, EGFR L858R/T790M, EGFR L858R/T790M/C797S and EGFRLT/L747S. JBJ-09-063 hydrochloride effectively reduces EGFR, Akt and ERK1/2 phosphorylation. JBJ-09-063 hydrochloride is effective across EGFR tyrosine kinase inhibitor (TKI)-sensitive and resistant models. JBJ-09-063 hydrochloride can be used for researching EGFR-mutant lung cancer[1].
JBJ-09-063 is remarkably effective at inhibiting cell growth and leads to a significant increase in apoptosis, even though H3255GR cells are resistant to gefitinib as a single agent, as they contain an EGFR T790M mutation[1].
JBJ-09-063 is effective in H1975 cells exogenously expressing the osimertinib-resistant mutations[1].
JBJ-09-063 exhibits IC50s of 50 nM and 6 nM in Ba/F3 cell when use alone or combination with Cetuximab [2].
JBJ-09-063 (3 mg/kg i.v., 20 mg/kg p.o.) exhibits favorable pharmacokinetics properties and is sufficiently stable to deliver good efficacy upon oral dosing[2].
