Small molecules that inhibit the metabolic enzyme NAMPT have emerged as potential therapeutics in oncology. As part of our effort in this area, we took a scaffold morphing approach and identified 3-pyridyl azetidine ureas as a potent NAMPT inhibiting motif. We explored the SAR of this series, including 5 and 6 amino pyridines, using a convergent synthetic strategy. This lead optimization campaign yielded
抑制代谢酶NAMPT的小分子已成为肿瘤学中的潜在疗法。作为该领域工作的一部分,我们采用了支架变形方法,并确定了3-吡啶氮杂环丁烷脲是一种有效的NAMPT抑制基序。我们使用收敛的合成策略探索了该系列的SAR,包括5和6个氨基吡啶。这种领先的优化运动产生了多种具有出色的体外效价和良好的ADME性能的化合物,最终达到了化合物27的水平。
