Abstract
Description
Technical Field
[0001] The present invention belongs to the field of medicinal chemistry and relates to a novel KAT6 inhibitor compound, a preparation method and use thereof. Background Art
[0002] KAT6 (lysine acetyltransferase 6) is a class of enzymes that plays a central role in epigenetic regulation. It regulates chromatin structure and gene transcriptional activity by catalyzing the acetylation of histone H3 at lysine 23 (H3K23). The KAT6 family comprises two isoforms: KAT6A (MOZ / MYST3) and KAT6B (MORF / MYST4). These two enzymes, through forming multiprotein complexes (for example, by binding to cofactors such as BRPF1 and ING5), participate in key biological processes such as stem cell differentiation, cell cycle regulation, and DNA damage repair. Studies have shown that KAT6A and KAT6B are significantly overexpressed in various malignancies, including breast, lung, ovarian, prostate, and acute myeloid leukemia (AML). Their overexpression is closely associated with increased tumor aggressiveness, chemotherapy resistance, and poor patient prognosis. For example, in breast cancer, KAT6A promotes cancer stem cell properties by activating the Wnt / β-catenin signaling pathway, while KAT6B impairs cell apoptosis by inhibiting the p53 pathway. In addition, KAT6 also regulates the migration and metastasis ability of tumor cells by acetylation of non-histone targets (such as transcription factors RUNX1 and FOXO3a).
[0003] The development of KAT6 inhibitors began with a systematic exploration of epigenetic targets. Patent WO 2016 / 198507A1, filed by Monash University, first reported the use of arylsulfonylhydrazides as novel KAT6A / B selective inhibitors. These compounds, by targeting the histone acetyltransferase (HAT) domain of MYST family proteins, block histone H3K9 acetylation, revealing the potential for overcoming drug resistance by inhibiting KAT6-mediated senescence escape mechanisms. Subsequently developed pyridothiazolesulfonylhydrazide derivatives, through pharmacokinetic optimization, achieved significant tumor suppression in animal models without exhibiting myelotoxicity, providing a new strategy for the treatment of solid tumors.
[0004] In recent years, Pfizer has been continuously developing new anticancer drugs around the MYST family lysine acetyltransferase (KAT) inhibitors. Based on the patents published in 2020 (WO 2020 / 254946 A1, WO 2020 / 254989 A1), the research team significantly improved the oral bioavailability, target selectivity and inhibition activity of KAT enzymes of the compounds through structure-activity relationship modification. In vitro and in vivo experiments have confirmed that tumor proliferation can be inhibited by regulating histone acetylation, but the selectivity of KAT family subtypes still needs to be improved. In 2022, Pfizer further proposed the combination therapy of KAT6 inhibitors with CDK4 inhibitors or anti-estrogens in the patent WO 2022 / 013369 A1, breaking through the clinical resistance limit of endocrine therapy and providing new strategies and hopes for cancer treatment. In the same year, Bayer developed a new type of acyl sulfonamide compound through the patent WO 2022 / 081807 A1, which showed high inhibition activity and broad-spectrum antitumor potential for KAT6A / B enzymes in in vitro experiments. These studies have jointly promoted the development of KAT inhibitors in multi-target combination therapy and overcoming drug resistance. Jiangsu Hengrui Medicine Co., Ltd. disclosed a new type of sulfonamide derivative and its application in cancer treatment through the patent WO 2023 / 016484 A1. The sulfonamide derivative involved in this patent is designed as a lysine acetyltransferase (KAT) inhibitor, which can effectively inhibit the growth of tumor cells such as breast cancer. In addition, other research institutions are also developing KAT6A / B inhibitors for related diseases. SUMMARY
