Monocrotaline is a toxic, pyrrolizidine alkaloid. It is used for inducing pulmonary diseases in rats. The alkaloid causes pulmonary artery hypertension, right ventricular hypertrophy, and pathological changes in the pulmonary vasculature. Monocrotaline is believed to act as an agonist at certain receptors, including the serotonin 5-HT2A receptor, and to interact with various enzymes, including cytochrome P450 enzymes.
