Three new fluorescent probes were synthesized for improving the method of studying donor-donor energy migration (DDEM). Each probe has two identical fluorescent 7-diethylaminocoumarin-3-carbonyl groups attached to a rigid bisteroid dodecacyclic spacer through additional inserts. In two probes, the inserts are β-Ala and L-Ser residues, which provide for a different nearest environment of the fluorophores. The third probe has identical β-Ala inserts.
合成了三种新的荧光探针,以改善供体-供体能量迁移(DDEM)研究的方法。每个探针都有两个相同的荧光7-二乙氨基香豆素-3-羧酰基,通过附加插入物连接到一个刚性双甾体十二环间隔上。在两个探针中,插入物为β-丙氨酸和L-丝氨酸残基,提供了不同的荧光团最近环境。而第三个探针则具有相同的β-丙氨酸插入物。
