considered the best treatment for erectile dysfunction.

IC50 Value: 5.22 nM [1]

Target: PDE 5

in vitro: Pretreatment with 1 umol/L sildenafil potentiated the phosphorylation of ERK1/ERK2, an

increase in the percentage of cells in S phase and cell proliferation, compared with serotonin

stimulation alone (P < 0.05) [2]. pretreatment of cells with sildenafilsuppressed serotonin-triggered

activation of calcineurin/NFATc2 signaling pathway and resultant cyclin A expression, CDK2

activation and cell proliferation, while the presence of DT-3 [a specific protein kinase G (PKG)peptideinhibitor]reversedtheeffectsofsildenafilonPASMCs[4]
