Abstract

The first reported synthesis of the DNA-PK inhibitor 3-cyano-6-hydrazonomethyl-5-(4- pyridyl) pyrid-[1H]-2-one (OK-1035) is described. The structure of OK-1035 was validated by X-ray crystallography. An IC50 value of 100 μM was determined for inhibition of DNA-PK, and this is approximately 12-fold higher than that reported previously.
