Win-62005 is a cyclic AMP phosphodiesterase III (PDE III) inhibitor with Kis of 25 and 26 nM for rat heart and canine aorta, respectively.
Win-62005 competitively inhibits cyclic GMP-inhibitable low Km cyclic AMP phosphodiesterase (PDE III) from rat heart and canine aorta with Ki values of 25±3 and 26±5 nM, respectively and is selective (at least 160-fold) for PDE III inhibition relative to other PDE isozymes[1].
After p.o. administration of 1 mg/kg Win-62005, LVdP/dtmax is significantly increased in 30 min and remains increased for at least 6 h[1].
