Used in pharmaceutical research as a key intermediate in the synthesis of vasodilator agents. Shows potential in the development of drugs targeting cardiovascular diseases due to its ability to inhibit phosphodiesterase enzymes, particularly PDE3, which plays a role in smooth muscle relaxation and platelet aggregation. Its derivatives are explored for improving heart function in conditions like congestive heart failure. Also investigated for anti-inflammatory and antithrombotic properties. Not used directly as a drug but serves as a structural scaffold in medicinal chemistry for optimizing bioavailability and potency in new therapeutic agents.
