Medicarpin is primarily used in agricultural and pharmaceutical applications due to its natural phytoalexin properties. It plays a key role in plant defense mechanisms, especially in leguminous plants, where it helps resist fungal and microbial infections. Because of this, medicarpin is studied for its potential in developing natural crop protection agents that reduce reliance on synthetic pesticides.

In medicine, medicarpin shows promise for its osteogenic activity, meaning it can stimulate bone formation. Research indicates it may help in treating osteoporosis by promoting the differentiation of osteoblasts and inhibiting osteoclast activity, which reduces bone loss. Its anti-inflammatory and antioxidant effects further support its therapeutic potential in metabolic and degenerative diseases.

Additionally, medicarpin is investigated for its anticancer properties, where it has demonstrated the ability to induce apoptosis in certain cancer cell lines. Its natural origin and low toxicity make it a candidate for nutraceutical and functional food development aimed at preventive healthcare.
