Abstract

NEW MATERIAL:A peptide of formula I (A is H, H-His-Asn-Leu-Glr-, H-Met-His- Asn-Leu-Gly-, H-Leu-Met-His-Asn-Leu-Gly- or H-Ile-Gln-Leu-Met-His-Asn-Leu- Gly-) and a salt thereof. EXAMPLE:The compound of formula II. USE:A remedy for hyperparathyroidism. PREPARATION:Individual amino acids and/or peptide fragments are condensed in the amino acid sequence of formula I to constitute a peptide. In the process, functional group in the side chain and/or alpha-amino groups of N-terminal amino acids are protected with protecting groups to convert the alpha-carboxyl group at the C-terminal tyrosine is converted into amido group. The protecting groups of the protected peptide of formula I are then eliminated by decomposition with an acid in one stage.

After dissolving 0 Et 1.513 K, it was washed three times each with 50% sodium bicarbonate solution and water. After drying the carbon layer with anhydrous sodium sulfate, it was concentrated under reduced pressure, and Et20 was added directly to the residue, and the resulting precipitate was collected as F. The target product C28:11346.9 was obtained by reprecipitation from MeOl-f-FJt20. TLC of this product V'i in solvent system 2 showed 2 spots. This is because the Tos group, which is the side chain protecting group of YamaS, is contained, but it was used in the next reaction without further purification.

Collect the 9th to 58th krakunyong C3G2 and freeze-dry them to obtain dried products C3GI and C3G223 Q +n
I got a 9. 03G2 was mixed with as little as possible of butanol-pyridine-water-0,6MAc0NH4 aqueous solution (5:3
:01:11) in the upper layer of a mixed solvent, and this was added to a column of Sephadex G-25 (2,5Xl15cnn
), and partition chromatography was performed using the upper layer of the above solvent as elution. At the elution night, fractionation was carried out in 85me increments and confirmed by the Folin-Lowry method.
9th fraction 03G2P1. 30th to 43rd fraction 03G2P2. 44th to 70th fractions 03G2P3 were collected and concentrated under reduced pressure to obtain 4 purified products C.
3G2P1, C3G2P2 and 2C3G2P3 were obtained. Dissolve 03G2P2 in as little 1M acetic acid as possible,
