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 muM was determined for inhibition of DNA-PK, and this is approximately 12-fold higher than that reported previously. (C) 2001 Elsevier Science Ltd. All rights reserved.
