ZL-2201 (ZL2201) is a highly potent, selective and orally bioavailable inhibitor of DNA-dependent protein kinase (DNA-PK) with IC50 of 1.1 nM.
ZL-2201 shows no significant activities against human mTOR, ATM, PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ PI3-kinases (all IC50 >1000 nM).
ZL-2201 exhibits antiproliferative activity against ATM-deficient NSCLC cell lines (H1373, H23, H522, H1395, H1703) with IC50 of 3.98-12.2 uM, selectively inhibits DNA-PK autophosphorylation at Ser2056.
ZL-2201 robustly inhibits NHEJ-mediated repair of exogenous DNA damage resulting in increased G2–M arrest and apoptosis in vitro.
ZL-2201 (60 mg/kg) inhibits DNA-PK autophosphorylation and exhibits potent antitumor efficacy in vivo of NCI-H1703 xenografts.
ZL-2201 could synergy with various DNA-damaging agents, significantly augments antitumor activity of DSB-inducing agents doxorubicin and IR.
