A dotriacontapeptide, H-Gln-Asp-Ser-Ser-Ser-Lys-Ala-Pro-Pro-Pro-Ser-Leu-Pro-Ser-Pro-Ser-Arg-Leu-Pro-Gly-Pro-Pro-Asn-Thr-Pro-Ile-Leu-Pro-Gln-Ser-Leu-Pro-OH, corresponding to the C-terminal sequence 116-147 of hCG-β proposed by Carlsen et al. was synthesized by stepwise fragment condensation, linking five fragments [Z-Gln-Asp(OBzl)-OH, Z-Ser(Bzl)-Ser-Ser-Lys(Boc)-NHNH2, Z-Ala-Pro-Pro-Pro-NHNHBoc, Z-Ser(Bzl)-Leu-Pro-NHNHBoc, and Z-Ser(Bzl)-Pro-Ser-NHNH2] to the hexadecapeptide reported in the preceding paper.
通过分步片段缩合,将五个片段[Z-Gln-Asp(OBzl)-OH、Z-Ser(Bzl)-Ser-Ser-Lys(Boc)-NHNH2、Z-Ala-Pro-Pro-NHNHBoc、Z-Ser(Bzl)-Leu-Pro-NHNHBoc 和 Z-Ser(Bzl)-Pro-Ser-NHNH2]连接到前一篇论文中报告的十六肽上,合成了该化合物。
