产品简述 pf-06463922 is a novel, orally available, cns-penetrant, atp-competitive inhibitor of alk/ros1 with ki of <0.02 nm, <0.07 nm, and 0.7 nm for ros1, alk (wt), and alk (l1196m), respectively.
详细说明 pf-06463922 demonstrates significant cell activity against alk and a large set of alk clinical mutations with ic50 ranging from 0.2 nm-77 nm. pf-06463922 exhibited subnanomolar cellular potency against oncogenic ros1 fusions and inhibited the crizotinib-refractory ros1(g2032r) mutation and the ros1(g2026m) gatekeeper mutation. compared with crizotinib and the second-generation alk/ros1 inhibitors ceritinib and alectinib, pf-06463922 showed significantly improved inhibitory activity against ros1 kinase. in vivo: pf-06463922 showed marked antitumor activity in tumor models expressing fig-ros1, cd74-ros1, and the cd74-ros1(g2032r) mutation. furthermore, pf-06463922 demonstrated antitumor activity in a genetically engineered mouse model of fig-ros1 glioblastoma.
3922还可以抑制ros1靶点,其作用力是alk的3倍,是目前ros1的2代药。
3922 应该是目前最广谱及活性的alk/ros抑制剂。它是微碱性,胃溶性稍高一些。它的肠吸收率高,即使肠溶也应不错。肠溶的副反应会小一些。胃溶肠溶都可以,空腹服用。

5.pf06463922可能和克唑替尼有同样的肝脏毒性,水飞蓟建议服用,密切检测肝功能。
6.试验组号病人是克唑替尼耐药后吃ldk378,ldk378耐药后服用3922,每天25mg,目前效果很好。
