The present invention is to provide a bicyclic compound represented by the following formula:
wherein Ring Q is pyridine or pyrimidine; Ring A is benzene or a heterocyclic ring;
G is Ring B optionally having a substituent(s) R
3
, or an amino optionally substituted by one or two selected from the group consisting of alkyl(s), aralkyl(s) and cycloalkyl(s); Ring B is benzene, a heterocyclic ring, a cycloalkane or a cycloalkene;
R
1
is a group selected from the following formulae:
R
2
and R
3
may be the same or different from each other, and each is cyano, nitro, etc.; m is 0, 1 or 2;
R
4
is hydrogen, a halogen, etc.; and
R
5
and R
6
may be the same or different from each other, and each is hydrogen, an optionally substituted alkyl, etc., or a pharmaceutically acceptable salt thereof, which is a large conductance calcium-activated K channel opener useful for treatment of pollakiuria, urinary incontinence, etc.
