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.

비티그-호너 반응, 콜빈 재배열 및 소노가시라 반응을 이용하여 피스아타놀 유도체를 용이하게 합성하였다. LPS로 유도된 RAW264.7 대식세포에서 합성된 화합물들에 대하여 항염증 활성을 조사한 결과, 화합물 6~8이 10 μM 농도에서 현저한 활성을 나타내었고, 화합물 7 (90.1%), 화합물 8 (60.8%), 화합물 6 (55.2%)은 세포독성을 나타내지 않았다.
