  Discovery of selective PDE4B inhibitors

  摘要：

  In this study the first PDE4B selective inhibitor is described. Optimization of lead 2-arylpyrimidine derivatives afforded a series of potent PDE4B inhibitors with >100-fold selectivity over the PDE4D isozyme. With a good pharmacokinetic profile, a selected compound exhibited potent anti-inflammatory effects in vivo and showed less emesis compared with Cilomilast. (C) 2009 Elsevier Ltd.

  The present invention is directed to compounds of Formula I: wherein X is O, S or NR 7 and R 1 -R 7 , Y and Z are set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof. Also described are methods for preparing the compounds of Formula I. The novel compounds of the present invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as chymotrypsin, trypsin, plasmin and urokinase. Certain of the compounds exhibit direct, selective inhibition of urokinase, or are intermediates useful for forming compounds having such activity.

  本发明涉及式 I 的化合物： 其中 X 是 O、S 或 NR 7 和 R 1 -R 7 、Y 和 Z，以及它们的水合物、溶剂或药学上可接受的盐，均已在说明书中阐明。还描述了制备式 I 化合物的方法。本发明的新型化合物是蛋白酶的强效抑制剂，特别是胰蛋白酶样丝氨酸蛋白酶，如糜蛋白酶、胰蛋白酶、凝血酶和尿激酶。其中某些化合物对尿激酶有直接的选择性抑制作用，或者是用于形成具有这种活性的化合物的中间体。
