High specific activity tritium labelling of some sigma-1 receptor agonists
- 98 Downloads
The high specific activity tritiation of (+)-SKF-10,047 (1) and N,N-dimethyltryptamine (4) is described. [N-allyl-3H] (+)-SKF-10,047 (3) was prepared by Lindlar catalyst tritiation of (+)-N-propargylnormetazocine (2) and [N-methyl-3H] N,N-dimethyltryptamine (6) was synthesized by the alkylation of N-methyltryptamine (5) with [3H] methyl iodide. Both sigma-1 synthetic agonist 3 and endogenous agonist 6 have been useful in studying this receptor.
