Glaucine
Based on 1 Customer Validation
Glaucine (O,O-Dimethylisoboldine) is an alkaloid extracted from Glaucium flavum that possesses various activities, including cough relief, bronchodilation, anti-inflammatory effects, analgesia, antipyretic properties, and anticancer effects. Glaucine acts as a selective and orally active inhibitor of phosphodiesterase 4 (PDE4), with a Ki of 3.4 µM in human bronchial tissues and polymorphonuclear leukocytes. Glaucine induces relaxation of human isolated bronchi by antagonizing calcium channels. Additionally, Glaucine inhibits the activation of NF-κB, leading to a reduction in the expression of the MMP-9 gene, thereby suppressing the migration and invasion of breast cancer cells. Therefore, Glaucine holds potential for research in asthma and breast cancer.

Glaucine (0.1 μM-1 mM; 30 min) produces a concentration-dependent inhibition of both spontaneous tension and histamine (HY-B1204)-induced tension in isolated human bronchial tissues[1]. Glaucine (10 μM-1 mM; 30 min) concentration-dependently inhibits the concentration of calcium ions in isolated human bronchial tissues induced by potassium depolarization[1]. Glaucine (0.1-3 mM; 120 min) concentration-dependently inhibits the release of peroxidase from human eosinophils[1]. Glaucine (0-50 μM; 24 and 48 h) inhibits the proliferation of MCF-7 cells induced by Phorbol 12-myristate 13-acetate (HY-18739) in a concentration-dependent manner[4]. Glaucine (0-30 μM; 36 h) significantly blocks the expression and activity of MMP-9 in MCF-7 cells induced by Phorbol 12-myristate 13-acetate (HY-18739) in a dose-dependent manner[4]. Glaucine (0-30 μM; 24 h) significantly inhibits the invasion of MDA-MB-231 cells in a dose-dependent manner[4].
