Temperature-dependent inhibition of phosphodiesterase-5 (PDE5) by pentoxifylline A Pentoxifylline inhibition curves for PDE5-activity at temperatures ranging from 37 to 20 °C. The doses of pentoxifylline are in logarithm of the concentration in mol/L. B Inhibition curves for PDE5-activity by pentoxifylline in % of normothermic inhibition curve at temperatures ranging from 37to 20 °C. The doses of pentoxifyllne are in logarithm of the concentration in mol/L
