Erinacine
Chemical structures of erinacines A-I
Erinacines are natural substances isolated from Hericium erinaceum. They belong to the group of cyathin diterpenoids (erinacines A-K, P, and Q) and are subjects of pharmacological research.
Erinacine A
Erinacine A, isolated from the cultured mycelia of Hericium erinaceum, the main representative of this compounds group, has an enhancing effect on nerve growth factor synthesis in vitro.[1] It also increases catecholamine in the central nervous system of rats.
Erinacine A has also been prepared by total synthesis.[2]
Erinacine E
Erinacine E is a kappa opioid receptor agonist.[3]
