The photoinduced release of several neurotransmitter amino acids (glycine, alanine, glutamic acid, β-alanine and γ-aminobutyric acid) was accomplished from ester cages based on a new photoremovable protecting group consisting of a coumarin built on the julolidine nucleus, namely a (11-oxo-2,3,5,6,7,11-hexahydro-1H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-9-yl)methyl group. Photolysis and steady-state
几种神经递质氨基酸(甘氨酸、丙氨酸、谷氨酸、β-丙氨酸和γ-氨基丁酸)的光诱导释放是基于一个新的光可去除保护基团的酯笼实现的,该保护基团由一个香豆素组成,该保护基团建立在朱洛啶核上,即11-氧代-2,3,5,6,7,11-六氢-1H-吡喃并[2,3-f]吡啶并[3,2,1-ij]喹啉-9-基)甲基。光解和稳态敏化研究表明,活性分子的释放发生在长波长的短辐照时间内,在 419 nm 处具有非常有希望的性能。鉴于对开发可被 UV A 甚至可见光辐射裂解的新型保护基团的兴趣,
