Overview
Cyclo-3-Hydroxymelatonin is a cyclic derivative of melatonin, primarily studied for its role in plant antioxidant mechanisms. Unlike melatonin, this compound exhibits enhanced stability under physiological conditions, making it valuable for research into oxidative stress and plant defense systems. It is synthesized through enzymatic pathways in plants and has garnered interest for its potential applications in agriculture and biotechnology. The compound is often utilized in laboratory settings to investigate reactive oxygen species (ROS) scavenging and stress tolerance in crops. Its unique structure allows it to interact with cellular components, providing insights into plant adaptation to environmental challenges. Researchers also explore its analogs for pharmaceutical and nutraceutical development.
Physical and Chemical Properties
Cyclo-3-Hydroxymelatonin is characterized by a molecular weight of 248.28 g/mol and a solubility profile favoring organic solvents. Its stability is maintained under controlled storage, though prolonged exposure to light or moisture may degrade the compound. The cyclic structure contributes to its resistance to enzymatic breakdown, unlike linear melatonin derivatives. Key spectroscopic properties include UV absorption peaks at 220 nm and 280 nm, useful for quantification in assays. The compound’s antioxidant capacity is measured via assays like DPPH and ABTS, where it demonstrates moderate to high activity. These properties make it a benchmark in comparative studies of plant-derived antioxidants.
Main Applications
In plant science, Cyclo-3-Hydroxymelatonin is employed to study oxidative stress responses, particularly in crops exposed to drought or UV radiation. Its ability to modulate ROS levels helps researchers develop stress-resistant plant varieties. Additionally, it serves as a reference standard in chromatographic analyses of melatonin-related metabolites. Beyond agriculture, the compound is investigated for potential therapeutic effects, such as neuroprotection and anti-inflammatory properties. However, most applications remain confined to preclinical research due to limited bioavailability in mammalian systems. Industrial uses include formulating plant growth enhancers and antioxidant additives for specialized horticultural products.
Safety and Storage
Cyclo-3-Hydroxymelatonin requires careful handling to prevent degradation or exposure. Lab personnel should use gloves, goggles, and fume hoods when working with the powder. The compound is not classified as highly hazardous, but prolonged skin contact may cause irritation. For storage, aliquot the powder into airtight, light-resistant containers with desiccants. Maintain temperatures at -20°C for extended stability, though short-term storage at 4°C is acceptable. Regularly monitor stored batches for discoloration or clumping, which indicate decomposition. Dispose of waste according to local regulations for organic compounds.
B2B Procurement Guide
When sourcing Cyclo-3-Hydroxymelatonin, prioritize suppliers specializing in plant biochemistry reagents. Request certificates of analysis (CoA) detailing purity (≥98% by HPLC), residual solvents, and batch-specific stability data. Bulk purchases (10+ grams) may qualify for discounts, but verify storage capacity to prevent waste. Consider suppliers offering custom synthesis for analogs or isotopic labeling, if required. Lead times vary; plan orders 4–6 weeks ahead for niche requests. For international procurement, confirm compliance with regional chemical import regulations, including Material Safety Data Sheets (MSDS) and customs documentation.
