Compound of formula:
wherein R¹, R², and R³ are hydrogen, alkyl, cycloalkyl, or phenyl or R¹ and R² taken together may form polymethylene, which may be intervened by one or more of oxygen, sulfur, and/or nitrogen and may have 1 or 2 lower alkyls as substituent; R⁴ is hydrogen or alkyl; R⁵ and R⁶ are hydrogen, alkyl, alkyloxy, or halogen, or taken together may form methylenedioxy.
The compounds show agonist, antagonist, or inverse agonist activities depending on the difference of their structure, whereby these are thought to be effective for antianxiety, antagonist against anesthetic, and antiencephalopathy.
该化合物的结构如下:其中 R¹、R² 和 R³ 可为氢、烷基、环烷基或苯基,或者 R¹ 和 R² 可以结合形成聚亚甲基,其中可以通过氧、硫和/或氮进行干预,并且可能具有1或2个较低烷基作为取代基;R⁴ 为氢或烷基;R⁵ 和 R⁶ 为氢、烷基、烷氧基或卤素,或者结合形成亚甲二氧基。这些化合物根据它们结构的差异显示激动剂、拮抗剂或逆拮抗活性,因此被认为对抗焦虑、对抗麻醉和对抗脑病有效。
