Stereoisomers of [3H]-N-allylnormetazocine bind to different sites in mouse brain.

(+)- and (-)-[3H]-N-allylnormetazocine (NANM) were synthesized and evaluated for binding to mouse brain membranes. Scatchard analysis of the saturable binding of (-)-[3H]NANM suggested a single class of binding sites with an apparent KD of 2.1 nM and an estimated maximum binding of 197 fmol/mg of protein. Increasing the concentration of Na+, K+, Mn++ or Ca… CONTINUE READING
