MedKoo CAT#: 406413

CAS#: 98293-88-0

Description: OK-1035 is a potent and selective DNA-PK inhibitor. When a synthetic peptide was used as a substrate, OK-1035 caused 50% inhibition of DNA-PK activity at 8 microM. OK-1035 inhibited the phosphorylation by DNA-PK of consensus peptide as well as that of recombinant human wild type-p53. Kinetic studies indicated that OK-1035 inhibited DNA-PK activity in an ATP-competitive manner.
