专利号:US-2024279231-A1 优先权日:2021-05-20 标题:Map4k4 inhibitors and methods of synthesis and use thereof 发明人:AWASTHI VIBHUDUTTA; EEDA VENKATESWARARAO 权利人:UNIV OKLAHOMA 摘要:The compound DMX-5804, IUPAC name 5-(4-(2-methoxyethoxy)phenyl)-7-phenyl-3,4a,7,7a-tetrahydro-4H-pyrrolo[2,3-d]pyrimidin-4-one, is a potent and selective inhibitor of mitogen-activated protein kinase kinase kinase kinase-4 (MAP4K4). The present disclosure describes a scalable and practical synthesis process for making DMX-5804. The process (1) doesn't rely on transition metals, (2) has reduced duration of reactions, (3) is streamlined with significantly improved yields using low cost raw materials, (4) includes no microwave-assisted reactions, (5) does not require column purification, and (6) generally results in crystalized products having over a 95% purity in each step. The present disclosure also describes DMX-5804 analogs and derivatives for use in inhibiting MAP4K4, and scalable and practical processes for making such DMX-5804 analogs.
