The present invention provides a novel fused bicyclic compound having an affinity to a receptor of mineral corticoid (MR), shown by the formula [I]:
wherein the ring A is a benzene ring having a substituent R
1
, fused to an adjacent 6-membered heterocyclic ring and further optionally having a substituent(s) other than R
1
, R
1
is an alkylsulfonylamino group etc.,
R
2
and R
3
are (a) the same of different and a hydrogen atom, an alkyl group or a substituted or unsubstituted aryl group, (b) combined each other to form an oxo group or (c) combined each other at its terminal together with the adjacent carbon atom to form a cycloalkyl group,
X is a group of ═N—, ═C(R
4
)— or —CH(R
4
)—,
R
4
is (a) a hydrogen atom, (b) a cyano group, (c) a halogen atom, (d) an alkyl group, (e) an alkenyl group, (f) a cycloalkyl group (g) an alkanoyl group, (h) a carbamoyl group or (i) a cycloalkenyl group,
Ar is an optionally substituted aromatic cyclic group and
a dotted line means presence or absence of a double bond,
or a pharmaceutically acceptable salt thereof,
which is useful as an antihypertensive agent etc.
