摘要:
Histone N-e-methyl lysine demethylases KDM2/7 have been identified as potential targets for cancer therapies. On the basis of the crystal structure of KDM7B, we designed and prepared a series of hydroxamate analogues bearing an alkyl chain. Enzyme assays revealed that compound 9 potently inhibits KDM2A, KDM7A, and KDM7B, with IC(50)s of 6.8, 0.2, and 1.2 mu M, respectively. While inhibitors of KDM4s did not show any effect on cancer cells tested, the KDM2/7-subfamily inhibitor 9 exerted antiproliferative activity, indicating the potential for KDM2/7 inhibitors as anticancer agents.
