Disclosed are thienopyridine derivatives of formula (I):
wherein one of A and B represents -S- and the other represents -CH=; X represents -O- or -NH-; R² represents hydrogen or lower alkyl; R¹ represents lower alkyl; and n represents 0 or 1; and their pharmaceutically acceptable salts thereof useful as anti-emetics and as migraine suppressants.
A thienoimidazopyridone derivative represented by general formula (I), a pharmacologically acceptable salt thereof, and a pharmaceutical composition comprising the same. In formula (I), A and B are different from each other, one representing -S- while the other representing -CH = ; X-Y-Z represents -NR²-CH = N- or -N = CH-NR²- wherein R² represents hydrogen, lower alkyl or -CHR³-(CH₂)n-R⁴ wherein R⁴ represents phenyl, n represents 0 or 1, and R³ represents hydrogen or lower alkyl; and R¹ represents lower alkyl. The invention compounds are excellent in bronchodilatory and immunomodulatory activities.
