synthesized and evaluated the activity of 3,6-disubstituted pyrazolo[1,5-a]pyrimidines as a new class of KDR kinase inhibitors. Starting with screening lead 1, potency against isolated KDR was fully optimized with 3-thienyl and 4-methoxyphenyl substituents at the 6- and 3-positions (3g, KDR IC(50)=19 nM), respectively. The synthesis and SAR of these compounds are described.
我们已经合成并评估了3,6-二取代的吡唑并[1,5-a]嘧啶作为一类新的KDR激酶抑制剂的活性。从筛选铅1开始,分别在6位和3位(3g,KDR IC(50)= 19 nM)处使用3-噻吩基和4-甲氧基苯基取代基完全优化了对分离的KDR的效力。描述了这些化合物的合成和SAR。
