Used in pharmaceutical research as a key intermediate in the synthesis of calcium channel blockers, particularly dihydropyridine-based drugs. These compounds are widely employed in the treatment of cardiovascular diseases such as hypertension and angina due to their ability to selectively block L-type calcium channels in vascular smooth muscle. The presence of functional groups like ester and amine allows for further chemical modifications, enabling the development of novel derivatives with optimized pharmacokinetic and pharmacodynamic profiles. Also explored in medicinal chemistry for structure-activity relationship (SAR) studies to enhance potency and reduce side effects in next-generation cardiovascular agents.
