* R1 group have contacts with Gln817 (2 hydrogen bounds, so it increases Sildenafil affinity), Phe820 (Sildenafil stacks against it), Try612 (hydrogen bound so it increases Sildenafil affinity [24]), Leu765 and Ala767 [21]. And there is hydrophobic interactions between the pyrazol ring and residues Val782, Leu785, Tyr612 and Phe820 [24].<br \>
