Synthesis and Initial SAR Studies of 3,6-Disubstituted Pyrazolo[1,5- a]pyrimidines: A New Class of KDR Kinase Inhibitors

Graphic We have 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...
