  名称：

  2-Phenylquinazolin-4(3H)-one, a class of potent PDE5 inhibitors with high selectivity versus PDE6

  摘要：

  In our efforts to minimize the side effects associated with low selectivity against the other PDE isozymes, a novel class of 2-phenylquinazolin-4(3H)-one derivatives were designed and prepared as potent PDE5 inhibitors with high selectivity against PDE6. The syntheses and SAR studies of such molecules were reported. (C) 2009 Elsevier Ltd. All rights reserved.
