Carpaine is primarily used in cardiovascular research due to its potent cardiotonic and hypotensive effects. It has been studied for its ability to modulate heart muscle contraction and regulate blood pressure, making it a compound of interest in developing treatments for heart failure and hypertension. The compound also exhibits anti-inflammatory and antioxidant properties, which support its traditional use in managing respiratory conditions such as bronchitis and asthma. Additionally, carpaine has shown potential in antimalarial studies, where it demonstrates activity against Plasmodium species by interfering with parasite development. Its uterotonic effect is also investigated for possible applications in obstetrics, particularly in controlling postpartum hemorrhage. Due to its biological activity, carpaine serves as a lead compound in the development of new pharmaceutical agents targeting circulatory and parasitic diseases.
