1-(4-(pyridin-2-yl)benzyl)imidazolidine-2,4-dione derivatives

Abstract

The invention relates to 1-(4-(pyridin-2-yl)benzyl)imidazolidine-2,4-dione derivative having the general Formula I wherein R1 is H, (C1-6)alkyl (optionally substituted with oxo, (C1-3)alkyloxy, (C1-3)alkyloxycarbonyl, halogen or CN), (C3-6)cycloalkyl or (C3-6)cycloalkyl(C1-3)alkyl, each cycloalkyl ring optionally comprising a heteroatom selected from O and S; R2 and R3 are independently H or (C1-3)alkyl; or R2 and R3 form together with the carbon atom to which they are bound a (C3-5)cycloalkyl group; R4 is H or 1 to 3 F substituents; R5 is H or 1 to 4 F substituents; R6 and R7 are independently H or F; X represents R8, OR8, NR8R9, R8 is (C5-7)cycloalkyl optionally comprising a heteroatom selected from O, S, SO and SO2; R9 is H or (C1-4)alkyl; R10 represents 1-3 substituents independently selected from H, (C1-3)alkyl, halogen, oxo, CN and CF3; Y is CF2, O, S, SO or SO2; or a pharmaceutically acceptable salt thereof, to pharmaceutical compositions comprising the same, as well as to the use of said 1-(4-(pyridin-2-yl)benzyl)imidazolidine-2,4-dione derivatives in the treatment of pain such as for example peri-operative pain, chronic pain, neuropathic pain, cancer pain and pain and spasticity associated with multiple sclerosis.
