Catechols and 3-hydroxypyridones as inhibitors of the DNA repair complex ERCC1-XPF
摘要:
Catechol-based inhibitors of ERCC1-XPF endonuclease activity were identified from a high-throughput screen. Exploration of the structure-activity relationships within this series yielded compound 13, which displayed an ERCC1-XPF IC50 of 0.6 mu M, high selectivity against FEN-1 and DNase I and activity in nucleotide excision repair, cisplatin enhancement and gamma H2AX assays in A375 melanoma cells. Screening of fragments as potential alternatives to the catechol group revealed that 3-hydroxypyridones are able to inhibit ERCC1-XPF with high ligand efficiency, and elaboration of the hit gave compounds 36 and 37 which showed promising ERCC1-XPF IC50 values of <10 mu M.
