Suzuki coupling of bromo precursors. The products were evaluated for activity at PI3K family enzymes and as platelet aggregation inhibitors and compared to reported unsubstituted analogues. The linear 6.7-fused product 13a and 13b were moderated potent but selective PI3Kδ isoform inhibitors (IC50=7.7 and 5.61μM). Good antiplatelet activity was noticed for the angular 7,8-fused compounds 22a, b, k and l
为了继续研究基于2-吗啉代-苯并恶嗪的化合物,这些化合物显示出对PI3K家族酶有用的活性或抗血小板活性,我们设计并合成了一系列线性的6.7融合,5,6-角融合和7,8角融合-芳基吗啉代萘恶嗪。由取代的2-羟基萘甲酸制备化合物,得到相应的硫代类似物8、9、15和19。然后将硫代产物转化为吗啉代取代的类似物。通过溴前体的Suzuki偶联引入芳基。评价产物对PI3K家族酶的活性,并作为血小板聚集抑制剂,并与报道的未取代的类似物进行比较。线性6.7融合产物13a和13b是中等强度的选择性PI3Kδ同工型抑制剂(IC50 = 7.7和5.61μM)。对于有角的7,8-融合的化合物22a,b,k和l,分别观察到良好的抗血小板活性,IC 50分别为3.0、14.0、2.0和5.0μM。抗血小板活性不依赖于PDE3。
