novel compounds derived from diversity-oriented synthesis with activity in multiple stages of the malaria parasite life cycle. Here, we report the optimization of a potent series of antimalarialinhibitors consisting of azetidine-2-carbonitriles, which we had previously shown to target P. falciparum DHODH in a biochemical assay. Optimized compound BRD9185 (27) has in vitro activity against multidrug-resistant

AXL is a member of the TAM (TYRO3, AXL, MER) subfamily of receptor tyrosine kinases. It is upregulated in a variety of cancers and its overexpression is associated with poor disease prognosis and acquired drug resistance. Utilizing a fragment-based lead discovery approach, a new indazole-based AXL inhibitor was obtained. The indazole fragment hit 11, identified through a high concentration biochemical
AXL 是受体酪氨酸激酶 TAM (TYRO3, AXL, MER) 亚家族的成员。它在多种癌症中被上调,其过度表达与疾病预后不良和获得性耐药性有关。利用基于片段的先导发现方法,获得了一种新的基于吲唑的 AXL 抑制剂。通过高浓度生化筛选鉴定的吲唑片段11通过筛选我们内部扩展的片段库 (ELF) 集合迅速改进为片段24 。由对接研究指导的后续片段优化为小鼠提供了中等暴露水平的强效抑制剂54 。类似物50的X射线晶体结构与 Mer 的 I650M 突变激酶结构域复合揭示了支架的关键结合相互作用。良好的效力与合理的激酶选择性、适度的体内暴露水平以及该系列结构信息的可用性相结合,使其成为进一步优化工作的合适起点。
