As a part of our program to develop OX1–CB1 bivalent ligands, we required a better understanding of the basic structure–activity relationships (SARs) of orexin antagonists. A series of SB-334867 analogues were synthesized and evaluated in calcium mobilization assays. SAR results suggest that the 2-methylbenzoxazole moiety may be replaced with a disubstituted 4-aminophenyl group without loss of activity
