Synthetic studies towards bottromycin
Thio-Ugi reactions are described as an excellent synthetic tool for the synthesis of sterically highly hindered endothiopeptides. S-Methylation and subsequent amidine formation can be carried out in an inter- as well as in an intramolecular fashion.

Properties of Amidinated Glucagons [PDF]
Porcine glucagon has been reacted with a series of alkyl imidates. The ɛ‐amino group and both the α and ɛ‐amino groups were modified and the subsequent glucagon derivatives were purified by ion‐exchange chromatography and characterized. The modified glucagons were compared with native glucagon in their ability to activate hepatic adenylate cyclase and ...
