All three are known as phosphodiesterase-5 (PDE5) inhibitors. By blocking the PDE-5 enzyme, these drugs help the smooth muscles of the penis to relax and increase blood flow. PDE5 inhibitors are generally the first choice of treatment for erectile dysfunction.y blocking the PDE-5 enzyme, these drugs help the smooth muscles of the penis to relax and increase blood flow.

Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors.FK is able to regulate glycolysis through allosteric inhibition, and in this way, the cell can increase or decrease the rate of glycolysis in response to the cellâs energy requirements. For example, a high ratio of ATP to ADP will inhibit PFK and glycolysis.
