项目摘要
Abstract. The objective of this research is to identify carbohydrate-compatible photolabile protecting groups
and light sources to facilitate the parallel on-surface synthesis of high-density glycan microarrays—e.g. glycan
chips—in a manner similar to the synthesis of gene chips. Instead of using monochromatic light and a single
photolabile protecting group to spatially control the extension of a linear polymer (DNA) on the microchip, as in
gene chip manufacture, irradiation with different wavelengths of light combined with wavelength-selective tem-
porary protecting groups will allow for constructing complex, branched glycans on a microchip surface. I aim to:
(1) identify carbohydrate-compatible photolabile protecting groups and optimal light sources to pair with each;
and (2) identify a pair of wavelength-selective (`chromatically orthogonal') protecting groups and demonstrate
their use in branched glycan synthesis, paving the way towards the parallel on-chip synthesis of high-density
glycan microarrays. Wavelength-selective photochemistry will be achieved by separating the absorptions of pho-
tolabile protecting groups to allow for selective excitation. Such high-density combinatorially-synthesized glycan
chips are expected to permit rapid epitope mapping and screening of the selectivity of glycan binding partners.
For example, exposing a dye-labeled lectin, antibody, or virus/bacteria/pathogen binding protein to the chip will
allow its binding specificity for numerous glycan structures to be determined from a single experiment. The ability
to synthesize high-density combinatorial libraries of carbohydrates will aid in resolving the structure-function
relationships of carbohydrates, help to understand the target epitopes of glycan binding partners, and accelerate
efforts to uncover the structure and function of the glycome.
抽象的。本研究的目的是确定碳水化合物相容的光不稳定保护基团
和光源以促进高密度聚糖微阵列(例如聚糖微阵列)的平行表面合成
芯片-以类似于基因芯片合成的方式。而不是使用单色光和一个单一的
光不稳定的保护基团,以在空间上控制线性聚合物(DNA)在微芯片上的延伸,如在
基因芯片的制作,用不同波长的光照射,结合波长选择性TEM,
多孔的保护基将允许在微芯片表面上构建复杂的支链聚糖。我的目标是:
(1)鉴定与碳水化合物相容的光不稳定保护基团和最佳光源以与每一个配对;
和(2)鉴定一对波长选择性(“色正交”)保护基,并证明
它们在支链聚糖合成中的应用,为高密度的并行芯片合成铺平了道路。
聚糖微阵列波长选择性光化学将通过分离光敏剂的吸收来实现。
不稳定的保护基团,以允许选择性激发。这种高密度组合合成的聚糖
预期芯片允许聚糖结合配偶体的选择性的快速表位作图和筛选。
例如,将染料标记的凝集素、抗体或病毒/细菌/病原体结合蛋白暴露于芯片,
允许其对许多聚糖结构的结合特异性从单个实验确定。的能力
合成高密度的碳水化合物组合库将有助于解析结构-功能
碳水化合物的关系,有助于了解聚糖结合伴侣的靶表位,并加速
努力揭示糖组的结构和功能。
