ATR inhibitor 2
(Synonyms: 2-氨基-6-氟-N-(5-氟-4-(4-(4-(噁丁环烷-3-基)哌嗪-1-羰基)哌啶-1-基)吡啶-3-基)吡唑并[1,5-A]嘧啶-3-甲酰胺,VX-803; M4344; ATR inhibitor 2) 目录号 : GC39645
VX-803 (M4344, ATR inhibitor 2) is an ATP-competitive, orally active, and selective inhibitor of ataxia telangiectasia and Rad3 related (ATR) kinase with Ki of < 150 pM. VX-803 (M4344) potently inhibits ATR-driven phosphorylated checkpoint kinase-1 (P-Chk1) phosphorylation with IC50 of 8 nM. VX-803 (M4344) exhibits potential antineoplastic activity.

VX-803 (M4344, ATR inhibitor 2) is an ATP-competitive, orally active, and selective inhibitor of ataxia telangiectasia and Rad3 related (ATR) kinase with Ki of < 150 pM. VX-803 (M4344) potently inhibits ATR-driven phosphorylated checkpoint kinase-1 (P-Chk1) phosphorylation with IC50 of 8 nM. VX-803 (M4344) exhibits potential antineoplastic activity.
M4344 is determined to be an adenosine triphosphate (ATP)-competitive, highly potent, and tight-binding inhibitor of ATR with a Ki of < 150 pM. Minimal inhibitory activity is observed against a large panel of unrelated protein kinases, with 308 of 312 kinases tested having a measured Ki corresponding to more than 100-fold selectivity. M4344 potently inhibits ATR-driven phosphorylated checkpoint kinase-1 (P-Chk1) phosphorylation with an IC50 of 8 nM. Profiling on a selected set of cancer cell lines shows synergy with several types of DNA damaging chemotherapeutics as well as PARP1/2 and CHK1 inhibitors.[1]
In monotherapy efficacy studies M4344 shows tumor stasis to regression in tumor models with alternative lengthening of telomeres (ALT). In combination with PARP inhibitors, tumor regression can be observed in triple-negative breast cancer xenograft models.[1]
