摘要

(−)-6-(7-Methoxy-2-trifluoromethylpyrazolo [1, 5-a] pyridin-4-yl)-5-methyl-4, 5-dihydro-3-(2H)- pyridazinone (KCA-1490) is a dual PDE3/4 inhibitor that exhibits potent combined bronchodilatory and anti-inflammatory activity. A survey of potential bicyclic heteroaromatic replacement subunits for the pyrazolo [1, 5-a] pyridine core of KCA-1490 has identified the 4- methoxy-2-(trifluoromethyl) benzo [d] thiazol-7-yl and 8-methoxy-2-(trifluoromethyl) ...
