Synthesis and characterization of 8-ethynyl-1,3-dihydro-benzo[b][1,4]diazepin-2-one derivatives: Part 2. New potent non-competitive metabotropic glutamate receptor 2/3 antagonists
摘要:
A series of 1,3-dihydro-benzo[b][1,4]diazepin-2-one derivatives was evaluated as non-competitive mGluR2/3 antagonists. Replacement of a cyano group by a five-membered heterocycle produced compounds inhibiting the binding of [H-3]-LY354740 to rat mGluR2 with low nanomolar affinity and consistent functional effect at both mGluR2 and mGluR3. Further modification to improve the physicochemical properties led eventually to compounds with the ability to reverse LY354740-mediated inhibition of field excitatory postsynaptic potentials in the rat dentate gyrus.

The present invention relates to compounds of general formula (I) wherein X is a single bond or an ethynediyl group, wherein, in case X is a single bond, R1 is halogen or phenyl which is optionally substituted with halogen, lower alkyl, halo-lower alkyl, lower alkoxy, halo-lower alkoxy, or cyano; In case X is an ethynediyl group, R1 is phenyl, optionally substituted with halogen, lower alkyl, halo-lower alkyl, lower cycloalkyl, lower alkoxy or halo-lower alkoxy; R3 is a 5 or 6 membered aryl or heteroaryl which are optionally substituted. The compounds according to the present invention can be used for treating or preventing acute and/or chronic neurological disorders such as psychosis, schizophrenia, Alzheimer's disease, cognitive disorders and memory deficits.
