piperitone is a natural compound from Piper nigrum L

Adipokinetic hormone Gryllus bimaculatus (Grybi-AKH), an adipokinetic hormone, mobilizes lipids and carbohydrates from the insect fat body, regulating energy homeostasis. It also enhances the locomotor activity of the two-spotted cricket and has potential applications in human medical studies for body weight regulation, weight loss induction, and alleviation of glycogen storage disorders [1] [2] [3].

4-Hydroxyhygric acid is a unique non-protein imino acid (a proline analogue) isolated from the leaves of five species of the tropical leguminous tree Copaifera. It serves as a key chemical defense metabolite for the plant. Studies have demonstrated that it functions as a potent inhibitor of larval development in the seed-feeding bruchid beetle Callosobruchus maculatus and exhibits significant feeding deterrence against the leaf-feeding lepidopteran Spodoptera littoralis. By modulating insect growth and behavior, it acts as a natural biopesticide within the tropical forest ecosystem.
