(M, 2H), 7.40 (s, 1H), 7.95 to 8.10 (m, 2H) [Action and effect] The compound of the general formula [I] and its acid addition salt of the present invention have excellent anti-cerebral ischemic action and It exhibits an antihypertensive hypoxic effect and is useful as a brain function improving agent or an antiamnestic agent, and also as a therapeutic agent for senile dementia. The compound according to the present invention may be administered alone, but may be orally or parenterally administered in various dosage forms as necessary or desired.
抗脳虚血試験 体重22〜30gのddY系雄マウスを1群6匹使用した。被検
薬を腹腔内(i.p.)に投与し、投与30分後に断頭した。
断頭後、頭部のgasping様呼吸が停止するまでの時間を
測定し、これを有意に延長する最小の投与量を求めた。Anti-Cerebral Ischemia Test A group of 6 ddY male mice weighing 22 to 30 g was used. The test drug was administered intraperitoneally (ip) and decapitated 30 minutes after the administration.
After decapitation, the time until the gasping-like breathing of the head stopped was measured, and the minimum dose that significantly prolongs this was determined.
抗低圧低酸素試験 体重23〜28gのddY系雄マウスを1群7〜10匹使用した。
被検薬を腹腔内(i.p.)に投与30分後、デシケータ内に
