Lypressin is a neurohypophysial hormone that regulates water, glucose, and salts in blood.
ChEBI: (2S)-N-[(2S)-6-amino-1-[(2-amino-2-oxoethyl)amino]-1-oxohexan-2-yl]-1-[[(4R,7S,10S,13S,16S,19R)-19-amino-7-(2-amino-2-oxoethyl)-10-(3-amino-3-oxopropyl)-16-[(4-hydroxyphenyl)methyl]-6,9,12,15,18-pentaoxo-13-(phenylmethyl)-1,2-dithia-5,8,11,14,17-pentazacycloeicos-4-yl]-oxomethyl]-2-pyrrolidinecarboxamide is a cyclic peptide.
Lypressin is synthetic 8-L-lysine vasopressin,a polypeptide similar to ADH. The lysine analog isconsidered more stable, and it is absorbed rapidly from thenasal mucosa. Lypressin (Diapid) is pharmaceutically availableas a topical solution, spray, 50 pressor units(185 g)/mL in 5-mL containers. Usual dosage, topical (intranasal),one or more sprays applied to one or both nostrilsone or more times daily.
Lypressin is a hormone used to prevent or control the frequent urination, increased thirst, and loss of water associated with diabetes insipidus (water diabetes). Its molecular weight is 1056.2 Dalton having an amino acid sequence of Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Lys-Gly-NH2. The Molecular Formula is: C46H65N13O12S2.
The CAS Number is: 50-57-7.
