生物活性

N-Acetyloxytocin is isolated and characterized in the neurointermediate lobe of the rat pituitary (NIL) and their presence in several brain areas of the rat[1].

体外研究
(In Vitro)

N-Acetyloxytocin is a post-translational modification of vasopressin (VP), and oxytocin (OT). The acetylated forms arc not restricted to the pineal gland, the tissue in which N-Acetyloxytocin is initially identified, but also occur in other systems producing OT and VP[1].

Amino acid composition and sequence of Kassinin, a tachykinin dodecapeptide from the skin of the African frog Kassina senegalensis. Methanol extracts of the skin of the African amphibian Kassina senegalensis contain a dodecapeptide, Kassinin, belonging to the family of tachykinins or physalaemin-like peptides. Kassinin, like all other natural tachykinins, possesses the characteristic C-terminal tripeptide Gly-Leu-Met-NH2 and a phenylalanine residue in position 5 from the C-terminus. The amino acid sequence in the N-moiety of the molecule differs sharply from that of the other tachykinins[1].
