DNA-PK

PI-103 is a potent, cell-permeable, ATP-competitive inhibitor of phosphatidylinositol 3-kinase (PI3K) family members with selectivity toward DNA-PK, PI3K (p110α), and mTOR.

PIK-75 is an imidazopyridine that selectively inhibits p110α with an IC50 value of 5.8 nM.2 It inhibits p110γ and p110β considerably less effectively with IC50 values of 0.076 μM and 1.3 μM, respectively.

NU-7441 (KU-57788) is a potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor. The IC50 values are 14, 1700, 5000, >100000 and >100000 nM for DNA-PK, mTOR, PI 3-K, ATM and ATR respectively.

Compound 401 is a cell-permeable pyrimido-isoquinolinone compound that acts as a potent, reversible, and ATP-competitive inhibitor of DNA-PK (IC50 = 280 nM) with ~19-fold selectivity over mTOR (IC50 = 5.3 μM).

NU7026 is a novel DNA-dependent protein kinase inhibitor that potentiates the cytotoxicity of topoisomerase II poisons used in the treatment of leukemia.

KU0060648 is a potent and selective inhibitor of DNA-dependent protein kinase (DNA-PK), (IC50 = 8.6 nM); with 20-1000 fold selectivity for DNA-PK over other PIKKs and a panel of 60 kinases. KU-0060648 enhances HDR efficiency and attenuates NHEJ frequency.

ETP-46464 is a potent and selective inhibitor of ATR with IC50 of 25 nM.

NU6027 is a potent inhibitor of cellular ATR activity (IC(50)=6.7 μM) and enhanced hydroxyurea and cisplatin cytotoxicity in an ATR-dependent manner.

CC-115 is a inhibitor of mTOR/DNA-PK (IC50= 21/ 13 nM).

CCT251545 is an orally bioavailable and potent inhibitor of WNT signaling with IC50 value of 5 nM.

Nedisertib, also known as M-3814, MSC2490484A, is an orally available inhibitor of DNA-dependent protein kinase (DNA-PK), with potential antineoplastic and chemo/radiosensitizing activities.

STL127705 is a Ku 70/80 heterodimer protein inhibitor, inhibits Ku70/80-DNA interaction, with an IC50 of 3.5 μM.

AZD-7648 is a potent and selective DNA-PK inhibitor. Anti-tumor activity.

YU238259 is an inhibitor of homology-dependent DNA repair (HDR), used for cancer research.

(R)-Nedisertib ((R)-M3814) is a less active R-enantiomer of Nedisertib, with an IC50 in the range of 7-30 nM for DNA-PK.

(Rac)-Nedisertib ((Rac)-M3814) is a racemate of Nedisertib, a potent DNA-PK inhibitor, with an IC50 of <3 nM.
