A series of 3-O-acyl-6-O-sulfate esters of morphine, dihydromorphine, N-methylmorphinium iodide, codeine, and dihydrocodeine were prepared and evaluated for their ability to bind to mu-, delta-, kappa(1)-, kappa(2)-, and kappa(3)-opiate receptors. Several compounds exhibited good affinity for the mu-opiate receptor. Morphine-3-O-propionyl-6-O-sulfate had four times greater affinity than morphine at the mu-opiate receptor and was the most selective compound at this receptor subtype.
