  8-Substituted Analogues of 3-(3-Cyclopentyloxy-4-methoxy-benzyl)-8-isopropyl- adenine: Highly Potent and Selective PDE4 Inhibitors

  摘要：

  3-(3-Cyclopentyloxy-4-methoxy-benzyl)-8-isopropyl-adenine V11294 (1) has been identified as a lead structure, which selectively inhibits human lung PDE4 (436 nM) and is also active in a number of in vitro and in vivo models of inflammation. Here we describe the synthesis and pharmacology of a series of highly potent 8-[(benzyloxy)methyl]-substituted analogues, with potencies in the range 10-300 nM. In addition, several compounds showed interesting PDE4 subtype specificities, for example, the 3-thienyl derivative 5v, which showed 6-10 nM potency at PDE4B, D3, and D5 and a 20- to 200-fold selectivity over A and D2, respectively.
