The synthesis of the fully protected octadecapeptide fragment (50–67) was achieved by combination of the subfragments 50–54,55–60 and 61–67. Single routes to two of these fragments are described but the fragment (55–60) was prepared by two different approaches. In this case salt-coupling techniques alleviated serious solubility problems. Fragment couplings were achieved using DCCI/HONSu.

Syntheses of two heptadecapeptide analogues of the hormone gastrin, viz. [Leu15] and [Leu5,Leu15]-porcine gastrin I are described. Both compounds exhibit the full biological activity of the natural hormone.
