Lead optimization of a high‐throughput screening hit led to the rapid identification of aminopyrimidine ZK 304709, a multitargeted CDK and VEGF‐R inhibitor that displayed a promising preclinical profile. Nevertheless, ZK 304709 failed in phase I studies due to dose‐limited absorption and high inter‐patient variability, which was attributed to limited aqueous solubility and off‐target activity against
高通量筛选命中的前导优化导致对氨基嘧啶ZK 304709的快速鉴定,ZK 304709是一种多靶点CDK和VEGF-R抑制剂,具有良好的临床前应用前景。然而,由于剂量限制的吸收和较高的患者间差异性,ZK 304709在I期研究中失败了,这归因于水溶性有限和针对碳酸酐酶的脱靶活性。为了解决脱靶活性谱图而进行的进一步的铅优化工作最终导致了磺胺嘧啶基的引入,这在药物化学中仍然是一种非常不寻常的方法。但是,磺胺嘧啶系列化合物很快显示出非常有趣的性质,最终鉴定出了纳摩尔级泛CDK抑制剂BAY 1000394,
