Axl 通常在许多癌症中过度表达,并与肿瘤生长、转移、耐药性和较差的总体生存率相关,因此已成为癌症治疗的一个有前景的靶点。然而,用于 Axl 抑制的新化学形式的可用性是有限的。在此,我们介绍了新型 Axl 抑制剂的开发和表征,包括一系列二苯基嘧啶二胺衍生物的设计、合成和构效关系 (SAR)。这些化合物中的大多数都表现出显着的抗 Axl 激酶活性。特别是,有前途的化合物m16显示出最高的酶抑制效力(IC 50 = 5 nM)并阻断多种肿瘤细胞的增殖效力( 42 个癌细胞系中 4 个的CC 50 <100 nM)。此外,化合物m16还具有较好的药代动力学特征和肝微粒体稳定性。所有这些有利的结果使m16成为进一步开发的良好领先治疗候选药物。

Starting with our previously described(20) class of CC chemokine receptor-3 (CCR3) antagonist, we improved the potency by replacing the phenyl linker of 1 with a cyclohexyl linker and by replacing the 4-benzylpiperidine with a 3-benzylpiperidine. The resulting compound, 32, is a potent and selective antagonist of CCR3. SAR studies showed that the 3-acetylphenyl urea of 32 could be replaced with heterocyclic ureas or heterocyclic-substituted phenyl ureas and still maintain the potency (inhibition of eotaxin-induced chemotaxis) of this class of compounds in the low-picomolar range (IC50 = 10-60 pM), representing some of the most potent CCR3 antagonists reported to date. The potency of 32 for mouse CCR3 (chemotaxis IC50 = 41 nM) and its oral bioavailability in mice (20% F) were adequate to assess the efficacy in animal models of allergic airway inflammation. Oral administration of 32 reduced eosinophil recruitment into the lungs in a dose-dependent manner in these animal models. On the basis of its overall potency, selectivity, efficacy, and safety profile, the benzenesulfonate salt of 32, designated DPC168, entered phase 1 clinical trials.

Structure-based discovery of potent inhibitors of Axl: design, synthesis, and biological evaluation
availability of new chemical forms for Axl inhibition is limited. Herein, we present the development and characterization of novel Axl inhibitors, including the design, synthesis, and structure–activity relationships (SARs) of a series of diphenylpyrimidine–diamine derivatives. Most of these compounds exhibited remarkable activity against the Axl kinase. In particular, the promising compound m16 showed the
