Witryna9 cze 1995 · Structure-activity relationships are discussed with regard to melatonin and bioisosteric naphthalenic compound 2. The Ki value for 4b was affected to a similar extent to that of melatonin by GTP-gamma-S or Mn2+ in competition experiments, suggesting an agonist profile for this compound. WitrynaTwenty three naphthalenic bio-isosteres of melatonin have been synthesized. The main structural variations concerned the acylamino substituents of the side chain and the alkoxy group on the 7-position of the naphthalene. Some of these compounds show greater affinity than melatonin itself for the melatonin receptor. The results of this …
