Pyrrole derivatives represented by the following formula:
wherein Ring Z is an optionally substituted pyrrole ring, etc.; W2 is -CO-, -SO2-, an optionally substituted C1-C4 alkylene, etc.; Ar2 is an optionally substituted aryl, etc.; W2 and Ar1 mean the following (1) and (2):
(1) W1 is an optionally substituted C1-C4 alkylene, etc.; Ar1 is an optionally substituted bicyclic heteroaryl having 1 to 4 nitrogen atoms as ring-forming atoms:
(2) W1 is an optionally substituted C2-C5 alkylene, an optionally substituted C2-C5 alkenylene, etc.; and Ar1 is an aryl or monocyclic heteroaryl, which are substituted by carboxyl, an alkoxycarbonyl, etc. at the ortho- or meta-position thereof with respect to the binding position of W1,
or a pharmaceutically acceptable salt thereof
