Synthesis of a morphine-6-glucuronide hapten, N-(4-aminobutyl)normorphine-6-glucuronide, and related haptens
摘要:
For use as a hapten in the radioimmunoassay of morphine-6-glucuronide 2 (M6G), N-(4-aminobutyl)normorphine-6-glucuronide 12 has been prepared, together with related haptens, using the imidate coupling method developed for synthesis of M6G; a rebuttal of recent critical comments on our synthesis of M6G is included.
an effective therapy is urgently needed. We followed the so-called “multitarget directed ligand” approach and designed 36 novel tacrine-phenothiazine heterodimers which were in vitro evaluated for their anticholinesterase properties. The assessment of the structure–activity relationships of such derivatives highlighted compound 1dC as a potent and selective acetylcholinesterase inhibitor with IC50

degradation in vitro, either against isolated aminopeptidases or humanplasma proteolytic enzymes. When administered either orally or intravenously, it was significantly more active than normal tuftsin in increasing the number of specific antibody secreting cells in spleen of mice immunized with sheep erythrocytes. Furthermore, the analogue exerted an enhanced stimulatory effect on the cytotoxic activity of
