Loganetin is primarily used in the synthesis of complex alkaloids, particularly in the production of indole alkaloids, which have significant pharmacological properties. It serves as a key intermediate in the biosynthesis of compounds like loganin, which is further converted into secologanin. Secologanin is a crucial precursor in the formation of various bioactive molecules, including those with anti-inflammatory, anticancer, and neuroprotective effects. Additionally, loganetin is of interest in research focused on understanding the biosynthetic pathways of plant-derived natural products, aiding in the development of novel therapeutic agents. Its role in the production of high-value alkaloids makes it valuable in both pharmaceutical and biochemical studies.
