Glaucine, a selective phosphodiesterase 4 (PDE4) inhibitor, is an alkaloid sourced from Glaucium flavum. It demonstrates significant biological activities such as bronchodilation, anti-inflammatory effects, and anticancer properties. With a Ki of 3.4 µM in human bronchial tissues and polymorphonuclear leukocytes, Glaucine promotes relaxation of isolated human bronchi through calcium channel antagonism. Furthermore, it inhibits NF-κB activation, which downregulates MMP-9 expression, thereby impairing the migration and invasion of breast cancer cells. Glaucine is relevant for research applications in asthma and breast cancer.
