Abstract
本发明公开了一种不对称硅基取代罗丹明衍生物及制备方法和应用,其衍生物结构式如式I所示,其中R为甲基、(S)‑2‑氨基‑4‑甲基戊基或(S)‑3‑氨基‑3‑羧基正丙基。本发明合成的不对称硅基取代罗丹明衍生物有近红外的荧光信号(650‑800nm),较宽的pH适用范围——酸碱耐受性好(pH=4.0‑11)。该系列不对称硅基取代罗丹明通过酰胺键的断裂及连接来控制内酯螺环的打开及关闭,从而实现染料分子的荧光调控。在酰胺键的一端连接不同的取代基R,能够与对应的目标蛋白酶特异识别结合,目标蛋白酶特异性地水解肽键使螺环打开,并释放近红外荧光,从而实现实时原位、灵敏快速地检测复杂体系中的蛋白酶。
Description
技术领域
本发明涉及有机分子荧光染料及其作为检测平台的蛋白酶识别检测领域。具体涉及一类不对称硅基取代罗丹明衍生物及合成和利用该类荧光分子实现生物体中亮氨酸氨基肽酶、γ-谷氨酰转肽酶的检测。
背景技术
罗丹明是一种氧杂蒽环结构的有机小分子化合物,水溶性好,荧光量子产率高,摩尔吸光系数高。传统罗丹明分子的荧光光谱多位于可见光区,在用于生物组织非侵入式荧光成像时容易受到生物样品的背景荧光干扰。硅取代罗丹明可调控分子荧光发射峰红移至近红外区域,因而具有荧光信号背景干扰低、组织穿透性强、光毒性小,是一个性质优良的生物荧光体系。
在荧光检测分析中,通过待测物与荧光分子的相互作用使荧光分子荧光信号改变可实现待测物的定性检测和定量分析。罗丹明内酯螺环结构中,螺环开关的状态对应罗丹明分子荧光信号开关的特性,已经作为一种快速高效的荧光开关调控机制被广泛运用于探针分子设计中。在生物系统中,蛋白与蛋白酶之间存在高灵敏、高特异性反应。将这类反应机制引入到荧光信号调控中具有较大意义。相关文献报道报道(J.Am.Chem.Soc.2013,135,409-414)Nagano等基于亮氨酸氨肽酶和亮氨酸肽具有特异结合快速水解的机制,设计构建了罗丹明荧光探针体系hydroxymethyl rhodamine(HMR)。该体系具有荧光背景低,信号灵敏度高的优势,但其分子骨架对酸性环境的耐受性差,限制了它的应用。
