  摘要：

  We previously identified KCA-1490 [(-)-6-(7-methoxy-2-trifluoromethyl-pyrazolo[1,5-alpha] pyridin-4-yl)-5- methyl-4,5-dihydro-3-(2H)-pyridazinone], a dual PDE3/4 inhibitor. In the present study, we found highly potent selective PDE4 inhibitors derived from the structure of KCA-1490. Among them, N-(3,5-dichloropyridin-4-yl)-7-methoxy-2-(trifluoromethyl) pyrazolo[1,5-alpha] pyridine-4-carboxamide (2 alpha) had good anti-inflammatory effects in an animal model.
