or a pharmaceutically acceptable salt or solvate thereof, wherein:
the dotted line represents an optional double bond;
X

is optionally substituted alkyl, cycloalkyl, aryl, heteroaryl or heterocycloalkyl;
X
2
is —CHO, —CN, optionally substituted amino, alkyl, or aryl;
or X
1
is optionally substituted benzofused heterocyclyl and X
2
is hydrogen;
or X
1
and X
