| abstract |
Compounds of formula (I), salts, solvates and physiologically functional derivatives thereof are provided: formula (I) wherein R1 and R2 is independently selected from hydrogen, optionally substituted C1-6alkyl, optionally substituted C3-6cycloalkyl, optionally substituted aryl, optionally substituted arylC1-4alkyl and optionally substituted arylC3-6cycloalkyl, wherein R1 and R2 are not both hydrogen, or R1 and R2, together with the nitrogen atom to which they are attached, are linked to form an optionally substituted 4-, 5-, 6- or 7-membered saturated ring, wherein one or more of the carbon atoms is optionally replaced by a heteroatom independently selected from N, O and S; R3 is an optionally substituted group of formula (a): wherein m and n are independently 0, 1, 2 or 3 and m+n is 2, 3 or 4; each Z is independently -CH2-, -NH-, -O- or -S-; and each Y is independently CH or N; R4 and R5 are independently selected from hydrogen, optionally substituted C1-C6 alkyl, optionally substituted C3-C6 cycloalkyl, optionally substituted aryl and optionally substituted arylC1-C4 alkyl; and R6, R7, R8 and R9 are independently selected from hydrogen, optionally substituted C1-C6 alkyl and optionally substituted arylC1-C4 alkyl, or R6 and R7 together form an optionally substituted C3-C6 cycloalkyl group, or R8 and R9 together form an optionally substituted C3-C6 cycloalkyl group. Methods of preparation and uses of the compounds in medicine for the treatment of a disorder mediated by GlyT1, for example schizophrenia, are also disclosed. |
