Disclosed are discrete PEGylated dyes, that is, dyes, generally ones that are fluorescent, but could also include chemi-luminescent or electrochemiluminescent and related dye or dye precursors, that have discrete PEG constructs chemically attached in various configurations on the dye, and in the entire range of constructs, discrete PEG compounds (polyethylene glycol oligomers that are made synthetically according to methods disclosed in U.S. Pat. No. 7,888,536 and US Pub. No. 2013/0052130). The dyes are modified in a range of ways to control or optimize the properties of water solubility, non-specific binding (in vitro), biodistribution (in vivo), cell internalization (non-cell or cell based assays in vitro, and in vivo diagnostics and therapy), as well as aggregation.
本发明涉及离散PEG化染料,即染料,通常是荧光染料,但也可能包括化学发光或电化学发光和相关染料或染料前体,在染料上以不同的配置化学连接离散的PEG构建物,并在整个构建物范围内,使用离散的PEG化合物(根据美国专利号7,888,536和美国公开号2013/0052130中披露的方法合成的聚乙二醇寡聚体)。这些染料以各种方式进行改性,以控制或优化其水溶性、非特异性结合(体外)、生物分布(体内)、细胞内吞作用(非细胞或细胞基础的体外试验,以及体内诊断和治疗),以及聚集。
