Overview
Glaucine is an isoquinoline alkaloid primarily extracted from the yellow horn poppy (Glaucium flavum). It has been studied for its pharmacological properties, including its role as a cough suppressant and bronchodilator. Historically, it has also been used in traditional medicine for its sedative and muscle relaxant effects. In modern applications, glaucine is synthesized or purified for use in pharmaceutical formulations. Its mechanism of action involves interactions with dopamine receptors and calcium channels, contributing to its therapeutic effects. Research continues to explore its potential in treating respiratory conditions and neurological disorders.
Physical and Chemical Properties
Glaucine appears as a white to off-white crystalline powder with a melting point of 120-122°C. It is soluble in organic solvents like ethanol and chloroform but has limited solubility in water. The compound is stable under recommended storage conditions but may degrade when exposed to light or moisture. The molecular structure of glaucine includes an isoquinoline backbone, which is characteristic of many bioactive alkaloids. Its pharmacological activity is attributed to this structure, enabling interactions with specific biological targets. Analytical methods such as HPLC and mass spectrometry are commonly used to verify its purity and identity.
Main Applications
Glaucine is primarily used in the pharmaceutical industry as an antitussive (cough suppressant) and bronchodilator. It is often formulated into syrups or tablets for respiratory conditions like chronic bronchitis or asthma. Its ability to relax smooth muscles in the airways makes it effective for symptom relief. Beyond respiratory applications, glaucine has been investigated for its potential neuropharmacological effects. Some studies suggest it may modulate dopamine receptors, offering possibilities for treating conditions like Parkinson's disease. However, these applications remain experimental and require further clinical validation.
Safety and Storage
Glaucine should be handled with care, as it may cause dizziness, nausea, or other central nervous system effects in high doses. Proper personal protective equipment (PPE), including gloves and goggles, is recommended during handling to minimize exposure. Storage conditions are critical to maintaining glaucine's stability. It should be kept in a tightly sealed container, away from light, moisture, and extreme temperatures. Bulk quantities are typically stored in controlled environments to prevent degradation. Disposal should comply with local regulations for pharmaceutical compounds.
B2B Procurement Guide
When procuring glaucine for industrial or pharmaceutical use, buyers should prioritize suppliers with verified certifications (e.g., GMP, ISO). Key specifications to confirm include purity (≥98%) and the absence of contaminants like heavy metals or residual solvents. Pricing varies based on quantity and purity, with reference ranges of $50-$200 per gram. Bulk purchases may qualify for discounts. Procurement teams should also ensure compliance with regional regulations, such as FDA or EMA guidelines, for pharmaceutical-grade materials. Long-term supplier relationships can enhance reliability and consistency in quality.
