Provided is a tryptophan-2,3-dioxygenase (TDO) and/or indoleamine-2,3-dioxygenase (IDO) inhibitor compound for use in medicine, which compound comprises the following formula: n n n n n n n n n n wherein X 2 , X 4 , X 10 , and X 11 may be the same or different and each is independently selected from C and N; X 1 , X 3 , X 5 , X 6 , X 7 , X 8 , and X 9 may be the same or different and each is independently selected from C, N and O; each bond having a dotted line may independently be a double bond or a single bond, provided that valencies at each atom are maintained; the dotted lines joining X 4 with the carbon atoms either side of X 2 are single bonds, and are only present when X 2 is absent, X 3 is absent and X 4 is C, and when these bonds are present the ring carbons on each side of X 2 are not directly bonded to each other; each R 1 may be present or absent and may be the same or different and is selected from H and a substituted or unsubstituted organic group, provided that the number of R 1 groups present is such that the valency of X 1 is maintained; each R 12 , R 13 , R 13′ , R 14 , R 15 and R 15′ may be present or absent and may be the same or different and each is independently selected from H and a substituted or unsubstituted organic group, provided that the number of such R groups present is such that the valency of the ring carbon atoms is maintained; R 16 may be present or absent and is selected from H and a substituted or unsubstituted organic group, provided that the number of R 16 groups present is such that the valency of X 2 is maintained; each R 17 may be present or absent and may be the same or different and is independently selected from H and a substituted or unsubstituted organic group, provided that the number of R 17 groups present is such that the valency of X 3 is maintained; each R 2 , R 3 , R 4 , and R 5 may be present or absent and may be the same or different and is selected from H and a substituted or unsubstituted organic group, provided that the number of such R groups present is such that the valencies of X 6 , X 7 , X 8 , and X 9 are maintained; each R 7 , R 8 and R 9 may be present or absent and may be the same or different and is selected from H and a substituted or unsubstituted organic group, provided that the number of such R groups present is such that the valencies of X 10 , X 11 , and X 5 are maintained; and R 6 is selected from H and a substituted or unsubstituted organic group, preferably H and a substituted or unsubstituted C 1 -C 6 alkyl group; and wherein any R group may form a ring with any other R group on an adjacent and/or proximal atom. |
