N-δ-BOC-D-Ornithine is derived from D-Ornithine Hydrochloride (O695545), which is the D-enatiomer and putative metabolite of the non-essential amino acid L-Orthinine. Stress response studies show intracerebroventricular D-Ornithine Hydrochloride weakly attenuated stress response in neonatal chick under acute stressful condition.
