Synthesis of quinolinomorphinan derivatives as highly selective δ opioid receptor ligands
摘要:
We have reported previously the novel delta opioid agonist KNT-127 which showed high affinity and selectivity for the delta receptor. Moreover, the analgesic effect of subcutaneously administered KNT-127 was more potent than that of a prototypical delta agonist (-)-TAN-67 in the acetic acid writhing test. This study of the structure-activity relationship of KNT-127 derivatives focused on the introduction of substituents onto the 5'-, 6'-, 7'- or 8'-position of the quinoline ring and revealed that many derivatives with 5'- or 8'-substituents showed high affinities and selectivities for the delta receptor. Especially, SYK-153 with an 8'-OH group showed the highest affinity and the most balanced and highest selectivity for the delta receptor among the synthesized compounds. (C) 2012 Elsevier Ltd.

demonstrate for the first time that 4H-1,2,6-thiadiazin-4-one (TDZ) can function as a chemotype for the design of ATP-competitive kinaseinhibitors. Using insights from a co-crystal structure of a 3,5-bis(arylamino)-4H-1,2,6-thiadiazin-4-one bound to calcium/calmodulin-dependent proteinkinasekinase2 (CaMKK2), several analogues were identified with micromolar activity through targeted displacement of
