cultures. Here, we synthesized 10 analogs bearing a 2-cyanoethyl group and administered them to mice to evaluate their anticonvulsant activity in maximal electroshock (MES)- and pentylenetetrazol (PTZ)-induced seizure tests, and their effects on motor coordination in a rotarod test. 3-(4-Oxo-4H-pyrido[3,2-e][1,3]thiazin-2-yl)[4-(trifluoromethoxy)phenyl]amino}propanenitrile (25) and 3-[(2,2-difluoro-2H-1
在我们寻找新型口服活性α-氨基-3-羟基-5-甲基-4-异恶唑丙酸(AMPA)受体拮抗剂的过程中,我们发现前导化合物2- [烯丙基(4-甲基苯基)中烯丙基的转化2-氰基乙基的氨基] -4H-吡啶并[3,2-e] [1,3]噻嗪-4-酮(4)显着提高了对大鼠海马培养物中AMPA受体介导的海藻酸盐诱导的毒性的抑制活性。在这里,我们合成了10个带有2个氰基乙基的类似物,并将其施用于小鼠以评估其在最大电击(MES)和戊四氮(PTZ)诱发的癫痫发作试验中的抗惊厥活性,以及它们在旋转试验中对运动协调的影响。3-(4-Oxo-4H-pyrido [3,2-e] [1,3]噻嗪-2-基)[4-(三氟甲氧基)苯基]氨基}丙腈(25)和3-[(2, 2-二氟-2H-1,3-苯并二恶唑-5-基)(4-氧代-4H-吡啶基[3,2-e] [1,3]噻嗪-2-基)氨基]丙腈(27)在癫痫发作试验中均表现出强的抗
