The present invention provides new oxime derivatives of the general formula (I), pharmaceutical compositions containing them and their use for the treatment and/or prophylaxis of conditions associated with altered glutamatergic signalling and/or functions, and/or conditions which can be affected by alteration of glutamate level or signalling in mammals. This invention further provides new oxime derivatives of the general formula (I) consisting of modulators of nervous system receptors sensitive to glutamate, which makes them particularly suitable for the treatment and/or prophylaxis of acute and chronic neurological and/or psychiatric disorders. In particular embodiments, the new oxime derivatives of the invention are modulators of metabotropic glutamate receptors (mGluRs). The invention further provides positive allosteric modulators of mGluRs and more specifically positive alSosteric modulators of mGluR4.
