N-Caffeoylputrescine (E)（Cat No.:R072624）is a naturally occurring phenylamide formed by the conjugation of caffeic acid with the polyamine putrescine. Found in various plants, including members of the Solanaceae family, it functions as part of the plant’s defense system against pathogens and environmental stress. Structurally, it belongs to the hydroxycinnamic acid amides, a class of bioactive secondary metabolites. Research has shown N-Caffeoylputrescine to exhibit antioxidant, antimicrobial, and anti-inflammatory properties, making it of interest for studies on plant physiology, stress adaptation, and potential therapeutic applications in oxidative stress-related conditions.
