systematic SAR study of a “caging” group showed a strong influence of the position of the donor dimethylamino group on the efficiency of photolysis of the DMAQ (2-hydroxymethylene-(N,N-dimethylamino)quinoline) caged acetate under one-photon near-UV or two-photon near-IR excitation. Photorelease of l-glutamate by the most efficient 8-DMAQ derivative strongly and efficiently activated glutamate receptors
对“笼形”基团的系统SAR研究显示,供体二甲基氨基基团的位置对DMAQ(2-羟基亚甲基-(N,N-二甲基氨基)喹啉)笼蔽乙酸酯在一个光子下的光解效率有很大影响。近紫外或双光子近红外激发。的光致升的最高效的8 DMAQ衍生物-谷氨酸强烈而有效地激活谷氨酸受体,产生大的,快速上升的响应类似于由谷氨酸从广泛使用的MNI-笼谷氨酸photoreleased引出。
