based inhibitors of xanthine oxidase is described. After a high-throughput screening campaign, an NMR based counterscreen was used to distinguish actives, which interact with XO in a reversible manner, from assay artefacts. This approach identified pyrimidone 1 as a reversible and competitive inhibitor with good lead-like properties. A hit to lead campaign gave compound 41, a nanomolar inhibitor of hXO
描述了新型,非嘌呤的黄嘌呤氧化酶抑制剂的鉴定。经过高通量筛选活动后,基于NMR的反筛选用于区分活性物,这些活性物以可逆方式与XO相互作用,与分析伪像分离。该方法将嘧啶酮1鉴定为可逆的竞争性抑制剂,具有良好的铅样性质。导致先头运动获得化合物41,一种hXO的纳摩尔抑制剂,口服给药后在高尿酸血症大鼠模型中具有功效。
