Synthesis and Inhibitor Activity to Phosphodiesterase of Thieno 3, 4-d Pyrimidine-2,4-Dione Derivatives
In search of novel phosphodiesterase (PDE) inhibitors, twelve compounds of thieno 3,4-d pyrimidiine-2,4-diones (V a-1) were designed and synthesized with cyanoacetic aicd and urethan taken as the starting materials. Condensation and cyclization were inv
