1,3-Dihydro-2,1,3-benzothiadiazol-2,2-diones and 3,4-dihydro-1H-2,1,3-benzothidiazin-2,2-diones as ligands for the NOP receptor
摘要:
A series of 1,3-dihydro-2,1,3-benzothiadiazol-2,2-diones (1) and 3,4-dihydro-1H-2,1,3-benzothidiazin-2,2-diones (II) were prepared. While the five-member ring series (I) did not show good affinity for opioid receptors, the six-member ring series (II) exhibited extremely high affinity and selectivity for the NOP receptor and showed full agonist activity, as determined by stimulation of GTPgamma[S-35] binding.

A series of phthalazine and 1, 2, 3-benzotriazine derivatives which have heterocyclylpiperidino groups was synthesized and tested for cardiotonic activity in anesthetized dogs. Several 6, 7-dimethoxyphthalazine derivatives showed relatively potent cardiotonic activity comparable to that of amrinone.
