F. Otvos et al., SYNTHESIS OF HIGH SPECIFIC ACTIVITY [15,16-H-3(2)]BUPRENORPHINE, Journal of labelled compounds & radiopharmaceuticals, 36(1), 1995, pp. 79-83
Tritium labelling of buprenorphine, a mixed agonist-antagonist opioid
ligand, was performed with a specific activity of 2.35 TBq/mmol (63.6
Ci/mmol) starting with 15,16-didehydrobuprenorphine. Labels at positio
ns 15 and 16 of the morphine skeleton proved to be sufficiently stable
under strong acidic or basic conditions.
