Abstract: A focused multiply N-methylated library of a cyclic hexapeptidic somatostatin analogue: MK678 cyclo(-MeAYwKVF-) was generated, which resulted in the unexpected observation of an efficacious tetra-N-methylated analogue, cyclo(-MeAYMewMeKVMeF-) with a potent inhibitory action on sensory neuropeptide release in vitro and on acute neurogenic inflammatory response in vivo. The analogue shows selectivity toward somatostatin receptor subtype 2 (sst2). Extensive 2D NMR spectroscopy and molecular dynamics simulation revealed the solution conformation of the analogue, which can be adopted as a lead for the further structure-activity relationship studies targeting neurogenic inflammation.
