✦ Synopsis
Syntheses of Novel Pyrazolomorphinans and Their Binding to µand χ-Opioid-receptors.
-A number of novel pyrazolomorphinans [cf. (V)/(VI)] are synthesized by reaction of the enolic morphinan diketones (III) with hydrazines and evaluated for their affinity at µ and χ-opioid receptors in radioligand binding assays. All the tested compounds possess binding affinity for both the receptors comparable to that of codeine. -(STROET-
