Biological Activity for Tadalafil

Tadalafil is a potent and highly selective PDE5 inhibitor (IC₅₀ = 5 nM). Exhibits > 2000-fold selectivity for PDE5 over PDEs 1,2,3 and 4 and 1000-fold selectivity over PDE6. Reduces blood pressure in hypertensive rats. Also delays tumor growth in a mouse model via inhibition of MDSC-mediated immunosuppression. Orally bioavailable.
