PDEs, phosphodiesterases design

The most X-ray intensive screening method was described by Card et al. [8] on the design of phosphodiesterase (PDE) inhibitors (Figure 1.7). The authors initially biochemically screened a 20,000 member library of small molecular weight (120-350 MW) core scaffold compounds against 5-PDE isoforms at 200 pM. Multiple isoforms of PDE were used in order to eliminate the number of false positives obtained from the screen. There were 316...
