Anandamide, an endocannabinoid neurotransmitter, acts as a ligand of the cannabinoid receptors. It possesses anti-proliferative effect which was accompanied by a reduction of cells in the S phase of the cell cycle. Anandamide also possesses the positive effects on eating behavior and motivation in mice. Recently was discovered, that anandamide reduced cryocapacitation and improved post-thaw sperm quality in the water buffalo (Bubalus bubalis).

Traumatic acid (TA) is a plant hormone (cytokinin) that in terms of chemical structure belongs to the group of fatty acids derivatives. It was isolated from Phaseolus vulgaris. It was discovered, that TA showed a stimulatory effect on antioxidative enzyme activity, reduced glutathione, thiol group content, and lipid peroxidation in physiological conditions. TA exhibited protective properties against ROS production. Thus, TA could be a potentially powerful agent with applications in the treatment of many skin diseases connected with oxidative stress and collagen biosynthesis disorders.
