General description

Crotaline is a macrocyclic compound belonging to the pyrrolizidine alkaloid family. It is naturally present in Crotalaria spectabilis.

Application

Crotaline has been used in hydrochloric acid (HCl) and injected into experimental animals to induce-pulmonary hypertension.

Biochem/physiol Actions

Crotaline induces pulmonary vascular syndrome in rats. It is considered toxic and results in hepatic cirrhosis, enlarged liver, sinusoidal obstruction syndrome and right ventricular hypertrophy.Monocrotaline is known to inhibit the growth of various experimental tumors.

Pulmonary hypertension is a chronic vascular disease characterized by pulmonary vasoconstriction and pulmonary arterial remodeling. Pulmonary arterial remodeling is mainly due to small pulmonary arterial wall thickening and lumen occlusion. Previous studies have described intravascular changes in lung sections using
