The effects of nineteen AHPA* derivatives were examined on morphine analgesia by tail-flick test in rats and on enkephalinase inhibition which was based on the formation of tyrosyl-glycyl-glycine from met-enkephalin. The correlation between the enhancement of morphine analgesia in vivo

It has been accepted that the periaqueductal gray matter of the mid brain (PAG) and the reticular formation of the medulla oblongata in the brain stem have antinociceptive roles in the pain control pathways of mammals, and met5-enkephalin may act

The biological activity of the two main metabolites of ubenimex in humans, (-)-N-[(2S,3R)-3-amino-2-hydroxy-4-(4'-hydroxy)phenylbutyryl]-L-leucine (OH-ubenimex) and (2S,3R)-3-amino-2-hydroxy-4-phenylbutyric acid [2S,3R)-AHPA) was examined. OH-Ubenimex was almost identical in inhibitory activity against mouse peritoneal resident macrophage aminopeptidases (APases) and the growth of IMC carcinoma

A bestatin analogue, (2S,3R)-3-amino-2-hydroxy-4-phenylbutanoyl-L-valine (AHPA-Val), from the culture filtrate of Streptomyces neyagawaensis SL-387 was obtained in a chemically defined medium containing DL-3-amino-3-phenylpropionic acid. AHPA-Val was 6 times (IC50 = 1.2 micrograms/ml) as strong as bestatin (IC50 = 7.0 micrograms/ml) against
