Abstract: SAR studies of a recently described SST5R selective benzoxazole piperidine lead series are described with particular focus on the substitution pattern on the benzyl and benzoxazole side-chains. Introduction of a second meta substituent at the benzyl unit significantly lowers residual hH1 activity and insertion of substituents onto the benzoxazole periphery entirely removes remaining h5-HT2B activity. Compounds with single digit nM activity, functional antagonism and favorable physicochemical properties endowed with a good pharmacokinetic profile in rats are described which should become valuable tools for exploring the pharmacological role of the SST5 receptor in vivo.
