关键词： Fatty acid synthase inhibitor Structure-based virtual screening S-phase arrest

摘要：

Fatty acid synthase (FASN), the key enzyme in de novo lipogenesis, is an attractive therapeutic target for diseases characterized by excessive lipid accumulation. Many FASN inhibitors have failed in the clinical trial phase, largely because of poor solubility and safety. In this study, we generated a novel small-molecule FASN inhibitor by structure-based virtual screening. PFI09, the lead compound, is easy to synthesize, and inhibits the lipid synthesis in OP9 mammalian cell line and Caenorhabditis elegans as well as the proliferation of several cancer cell lines via the blockade of FASN. Mechanistic investigations show that PFI09 induces S-phase arrest, cell division reduction and apoptosis. We also develop a chemically stable analog of PFI09, MFI03, which reduces the proliferation of PC3 tumor cells both in vitro and in vivo, without toxicity to mice. In summary, our data suggest that MFI03 is an effective FASN inhibitor and a promising antineoplastic drug candidate. Copyright © 2021 Elsevier Masson SAS. All rights reserved.
