Used primarily in pharmaceutical research and development, this compound functions as a potent inhibitor targeting specific enzymes involved in cellular signaling pathways. It is particularly investigated for its role in treating cardiovascular diseases and erectile dysfunction due to its ability to selectively inhibit phosphodiesterase enzymes, enhancing blood flow and smooth muscle relaxation. Its formulation with 2-hydroxypropane-1,2,3-tricarboxylate (citric acid) improves solubility and bioavailability, making it suitable for oral dosage forms. Ongoing studies explore its potential in managing pulmonary hypertension and benign prostatic hyperplasia, leveraging its targeted mechanism of action and favorable pharmacokinetic profile.
