New dibenzofuranone-oxime derivatives were designed based on active structures of oxime esters. Compounds of the proposed group were synthesized using 3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1(2H)-one oxime and aromatic acid chlorides. The anticonvulsant activity of the new compounds was studied. The structure— activity relationship was analyzed. Compound 1a [3,4,6,7,8,9-hexahydrodibenzo[b,d]furan-1(2H)-one O-(3,4-dichlorobenzoyl)oxime] was the most active compound after i.p. injection to mice in the maximal electroshock test over a wide dose range of 20 – 100 mg/kg. Compound 1a at doses of 10 and 30 mg/kg exhibited antihypoxic activity in a hypoxia test with hypercapnia in a hermetic chamber and anti-ischemic activity at a dose of 10 mg/kg in a rat ischemic stroke model.
基于肟酯的活性结构设计了新型二苯并呋喃酮肟衍生物。使用3,4,6,7,8,9-六氢二苯并[b,d]呋喃-1(2H)-酮肟和芳香酰氯合成了该组化合物。研究了新化合物的抗惊厥活性。分析了结构-活性关系。化合物1a[3,4,6,7,8,9-六氢二苯并[b,d]呋喃-1(2H)-酮O-(3,4-二氯苯甲酰基)肟]是腹腔注射后最有活性的化合物。在最大电击试验中向小鼠注射 20 – 100 mg/kg 的宽剂量范围。 10和30mg/kg剂量的化合物1a在密闭室中高碳酸血症的缺氧试验中表现出抗缺氧活性,并且在大鼠缺血性中风模型中以10mg/kg剂量表现出抗缺血活性。
