Consistent with previous work on 122 GABAA receptors, we found in Xenopus oocytes that 5 MAC cyclopropane enhanced the effect of GABA on 122 GABAA receptors by only 76%, and by a nearly identical enhancement in 132, and 632 receptors.
与先前在α1β2γ2 γ-氨基丁酸 A 受体所得到的相符,我们发现在爪蟾卵上,5倍的环丙烷最低肺泡有效浓度增加了γ-氨基丁酸在α1β2γ2 γ-氨基丁酸 A 受体上的作用仅76%,在α1β3γ2 γ-氨基丁酸 A 受体及α6β3γ2 γ-氨基丁酸 A 受体上的加强作用也几乎一致。

Chiral ligands mentioned above and their complexes with acetate copper were used as enantio-selective catalysts in asymmetric cyclopropanation reactions of diazoacetate and 1,1-diphenyl ethylene. Investigations indicate that all of them reveal certain optical-selective capability, but chiral C2-symmetric 2,6-bispyridine ligands show better catalytic capability than chiral asymmetric schifF-base ligands.
选择了2个手性2,6-吡啶双噁唑啉配体和6个手性不对称席夫碱配体与醋酸铜形成的配合物作为催化剂,对重氮乙酸乙酯与1,1-二苯乙烯不对称环加成进行催化反应,发现这8个催化剂对1,1-二苯乙烯的不对称环丙烷化反应都表现出了一定的光学活性诱导能力,手性2,6-吡啶双噁唑啉-铜类具有比手性Schiff碱-铜类更好的催化性能。
