The present invention relates to small molecule compounds that allosterically inhibit ALC1 (CHD1L) and which induce the trapping of PARP1, PARP2 and/or PARP3 on chromatin or at DNA damage sites. Disruption of the chromatin remodeling forces of ALC1 through these agents enables a highly selective therapy for targeting the DNA damage functions of PARP enzymes in several proliferative diseases, notably BRCA-deficient cancers. Via inhibition of the enzymatic activity, the compounds engage the synthetic lethality between BRCA1/2 and ALC1. By trapping PARP enzymes, inhibitors of ALC1 potentiate the cancer cell killing properties of PARP inhibitors, enable therapeutic approaches where ALC1 is amplified as an oncogene, therapeutically make it possible to overcome PARP inhibitor resistance mechanisms and enable an alternative approach to the treatment of germline or acquired BRCA1/BRCA2 deficiency, including tumors defined by "BRCAness" or other changes in DNA repair networks.
本发明涉及小分子化合物,其以变构抑制ALC1(CHD1L),并在染色质或DNA损伤部位诱导PARP1、PARP2和/或PARP3的固定。通过这些药物破坏ALC1的染色质重塑力量,可以高度选择性地治疗几种增生性疾病中PARP酶的DNA损伤功能,特别是BRCA缺陷性癌症。通过抑制酶活性,这些化合物参与BRCA1/2和ALC1之间的合成致死作用。通过固定PARP酶,ALC1的抑制剂增强了PARP抑制剂的癌细胞杀伤性能,使治疗方法能够在ALC1作为癌基因被放大时使用,治疗上能够克服PARP抑制剂耐药机制,并且使治疗BRCA1 / BRCA2缺陷的生殖细胞系或获得性缺陷的肿瘤,包括“BRCAness”或其他DNA修复网络变化定义的肿瘤成为可能的替代方法。
