Natural Coumarin Derivatives Targeting Melanoma
Current Medicinal ChemistryAbstract: In general, a cancerous process starts from uncontrolled cell growth, apoptosis, and rapid proliferation of cellular clones, as well as, reactive oxygen species (ROS) and imbalance of ROS-antioxidant production also could be involved in the genesis of the disease. Cancer has accounted for millions of deaths worldwide every year, representing

Naturally Occurring Plant Coumarins
1978Over the past 150 years, since Vogel in 1820 isolated the parent oxygen heterocycle, coumarin (1) from Coumarouna odorata = Dipteryx odorata (1), coumarins have been recognized as widely distributed plant products. The vast majority carry an oxygen substituent at C-7; consequently 7-hydroxycoumarin [umbelliferone, (2)], one of the most widely ...
