or (R 3 and R 4 ), and/or (R 4 and R 5 ), and/or (R 5 and R 6 ), and/or (R 6 and R 7 ), and/or (R 7 and R 8 ), together with the atom(s) they are attached, form a 3- to 8-membered saturated, partially or fully unsaturated ring having 0, 1 or 2 heteroatoms independently selected from —NR 13 —, —O—, —S—, —SO— or —SO 2 -, and said ring is optionally substituted with at least one substituent R 12 ;
provided that
when X is O, R 5 and R 6 are absent,
when X is N, R 6 is absent,
when X is S, R 5 and R 6 are absent, or at least one of R 5 and R 6 is oxo,
when one of R 3 and R 4 is oxo, the other is absent,
when one of R 7 and R 8 is oxo, the other is absent, and
