Milrinone is a phosphodiesterase inhibitor with positive inotropic and vasodilator effects that are useful in the treatment of ventricular dysfunction after cardiac surgery. However, the pharmacokinetics of the drug have been investigated only in healthy volunteers and in patients with

The inhibitors of the cGMP-inhibited, low-Km cAMP phosphodiesterase--milrinone and OPC 3911--and an inhibitor of a non-cGMP-inhibited low-Km cAMP phosphodiesterase--rolipram--were used to evaluate the functional importance of the two cAMP phosphodiesterase activities in vascular smooth muscle and in platelets. Vinpocetine, an

We have identified and highly purified a "low Km" cAMP phosphodiesterase from bovine cardiac muscle. This phosphodiesterase was inhibited by low concentrations of cGMP and has, therefore, been temporarily designated as cGMP-inhibited phosphodiesterase. After a 16,000-fold increase in specific activity

The cardiac in vitro effects of R 80122, a novel phosphodiesterase (PDE) inhibitor, were investigated and compared with those of the reference compound milrinone and of the calcium-sensitizer adibendan. In guinea pig left atria, both milrinone and R 80122 increased

Alternative splicing (AS) contributes to gene diversification, but the AS program during germline development remains largely undefined. Here, we interrupted pre-mRNA splicing events controlled by epithelial splicing regulatory protein 1 (ESRP1) and found that it induced female infertility in mice.
