摘要:
Benzofuran derivatives represented by formula (I) or salts thereof: (wherein R1 represents a phenyl group or a hydrogen atom; k is 0 or 1; each of m, n, o, p, and q is an integer of 0 to 5; and each of R2 and R3 represents a hydrogen atom or a hydroxyl group, or R2 and R3 together represent an oxygen atom, with proviso that k, q, and m, or n, o, and p are not simultaneously 0). The compounds inhibit phosphorylation of STAT 6 and are useful in the treatment or prevention of allergic diseases.
