iminodiacetic acid monoallyl ester (7), have been employed. The key steps of the synthesis are as follows: (i) stepwise coupling of one amino acid and 6 to the secondary amino group of the linker; (ii) removal of the 2-nitrobenzenesulfonyl group and SPPS by the Fmoc chemistry, using 7 as the penultimate and tert-butoxycarbonyl (Boc) protected glycine as the last amino acid; (iii) removal of the 4-methoxytrityl

A composition in the form of an injectable solution includes: amylin, an amylin receptor agonist or an amylin analog; at least one ionic species; and an amphiphilic compound having a hydrophilic skeleton HB, substituted by at least one hydrophobic radical -Hy according to formula (I). A composition further is characterised in that it also has prandial insulin. In one embodiment, the composition also has GLP-1, GLP-1 analogs, and GLP-1 receptor agonists, commonly called GLP-1 RA.

amino group. The 1:1 complexation in the chloroform was dependent on the size of the alkyl groups on the peripheral aminomethyl nitrogen atom. The diethyl substitute complexed more strongly than the dimethyl and dipropyl counterparts. The complexation of zinc (diethylamino)methyl-porphyrin with an Nα,Nim(π)-protected histidine was 260-fold stronger than that with the above Nα,Nim(τ)-protected histidine
