Disclosed are naphthyridine derivatives represented by formula (I)
wherein:
X represents hydrogen; lower alkyl; aralkyl; substituted or unsubstituted aryl; substituted or unsubstituted aromatic heterocyclic group; -NR¹R² wherein R¹ and R² independently represent hydrogen or lower alkyl;
wherein W represents N or CH, Z represents a single bond, oxygen or NR³ (wherein R³ represents hydrogen, lower alkyl or benzyl) and n1 and n2 represent an integer of 1 to 3; or substituted or unsubstituted thiazolinyl; and
Y is a single bond or alkylene
and pharmaceutically acceptable salts thereof. The compounds show potent anti-inflammatory activity and are expected to be useful in treating rheumarthritis.
