The present invention relates to novel quinazolinone derivatives of formula (I) as well as pharmaceutical compositions containing these compounds. The compounds of formula (I) as provided herein can act as positive allosteric modulators of metabotropic glutamate receptor subtype 4 (mGluR4), and can thus be used as therapeutic agents, particularly in the treatment or prevention of conditions associated with altered glutamatergic signalling and/or functions or conditions which can be affected by alteration of glutamate level or signalling. 3. The compound of claim 1 , wherein each Rand each Ris independently selected from Calkyl claim 1 , —(Calkylene)-OH claim 1 , —(Calkylene)-O(Calkyl) claim 1 , —(Calkylene)-SH claim 1 , —(Calkylene)-S(Calkyl) claim 1 , —(Calkylene)-NH claim 1 , —(Calkylene)-NH(Calkyl) claim 1 , —(Calkylene)-N(Calkyl)(Calkyl) claim 1 , —(Calkylene)-halogen claim 1 , —(Calkylene)-(Chaloalkyl) claim 1 , —(Calkylene)-O—(Chaloalkyl) claim 1 , —(Calkylene)-CN claim 1 , —(Calkylene)-CHO claim 1 , —(Calkylene)-CO—(Calkyl) claim 1 , —(Calkylene)-COOH claim 1 , —(Calkylene)-CO—O—(Calkyl) claim 1 , —(Calkylene)-O—CO—(Calkyl) claim 1 , —(Calkylene)-CO—NH claim 1 , —(Calkylene)-CO—NH(Calkyl) claim 1 , —(Calkylene)-CO—N(Calkyl)(Calkyl) claim 1 , —(Calkylene)-NH—CO—(Calkyl) claim 1 , —(Calkylene)-N(Calkyl)-CO—(Calkyl) claim 1 , —(Calkylene)-SO—NH claim 1 , —(Calkylene)-SO—NH(Calkyl) claim 1 , —(Calkylene)-SO—N(Calkyl)(Calkyl) claim 1 , —(Calkylene)-NH—SO—(Calkyl) claim 1 , and —(Calkylene)-N(Calkyl)-SO—(Calkyl).4. The compound of claim 1 , wherein Xis C(-L-R).5. The compound of claim 1 , wherein Xis C(R) claim 1 , Xis C(-L-R) claim 1 , Xis C(R) claim 1 , and Xis C(R).6. The compound of claim 1 , wherein Ris selected from cycloalkyl claim 1 , aryl claim 1 , heterocycloalkyl claim 1 , and heteroaryl claim 1 , wherein said cycloalkyl claim 1 , said aryl claim 1 , said heterocycloalkyl claim 1 , and said heteroaryl are each optionally substituted with one or more ...
