Discovery of CC Chemokine Receptor-3 (CCR3) Antagonists with Picomolar Potency
摘要:
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.

Synthesis and biological evaluation of novel 5,6‐dihydrobenzo[

]quinazoline derivatives as FLT3 inhibitors
kinase 3 (FLT3) is widely expressed and often mutated in acute myeloid leukemia (AML), which makes it an important target for the treatment of AML. The structure-based synthesis and biological evaluation of 5,6-dihydrobenzo[h]quinazoline derivatives as FLT3 inhibitors have been studied in this paper. III-1a, III-1c, III-2a, III-2c, and III-4a displayed comparable inhibitory potency against FLT3-ITD and
Fms 样酪氨酸激酶 3 (FLT3) 在急性髓性白血病 (AML) 中广泛表达并经常发生突变,这使其成为治疗 AML 的重要靶点。本文研究了作为FLT3抑制剂的5,6-二氢苯并[ h ]喹唑啉衍生物的结构合成和生物学评价。III-1a、III-1c、III-2a、III-2c和III-4a对 FLT3-ITD 显示出相当的抑制效力,并对 MV4-11 显示出显着的抗增殖活性。
