Synthesis and biological evaluation of 2,5-dihydropyrazolo[4,3-c]quinolin-3-ones, a novel series of PDE 4 inhibitors with low emetic potential and antiasthmatic properties
摘要:
A novel series of 2,5-dihydropyrazolo[4,3-c]quinolin-3-one has been prepared. These compounds showed good PDE 4 inhibitory activity and weak affinity for rolipram's binding site. They also exhibited a good anti-inflammatory profile without emetic side effects. (C) 2000 Published by Elsevier Science Ltd.
