Enzyme‐labile protectinggroups have emerged as a green alternative to conventional protectinggroups. These groups introduce a further orthogonal dimension and eco‐friendliness into protection schemes for the synthesis of complex polyfunctional organic molecules. S‐Phacm, a Cys‐protectinggroup, can be easily removed by the action of a covalently immobilizedPGAenzyme under very mild conditions.

In accordance with their common but also divergent physiological actions, human urotensinII (1) and urotensin II-related peptide (2) could stabilize specific urotensinIIreceptor (UTR) conformations, thereby activating different signaling pathways, a feature referred to as biasedagonism or functional selectivity. Sequential N-methylation of the amides in the conserved core sequence of 1, 2, and
