As a contribution to the problem of the intercalation and photobinding of psoralens to DNA, model compounds were prepared in which the psoralen ring is linked to thymine by a polymethylene bridge. The ring-ring intramolecular interaction in the models was assessed by hypochromism measurement in the UV.
The surface of a polymer may be modified by contacting the polymer with a two or three membered heterocyclic compound I under electromagnetic irradiation. The heterocyclic compound may be substituted and may comprise linking units and/or probes so as to render the combination of polymer and compound I able to bind biomolecules and/or to be identified. Compounds I are preferably substituted psoralens, and the modified polymers can be used in e.g. ELISA methods, bioreactors, chromatography, solid phase chemical synthesis or bio-sensors.
在电磁辐照下,可将聚合物与二元或三元杂环化合物 I 接触,对聚合物表面进行改性。杂环化合物可以是取代的,也可以包括连接单元和/或探针,从而使聚合物与化合物 I 的组合能够结合生物分子和/或进行识别。化合物 I 最好是取代的补骨脂素,改性聚合物可用于 ELISA 方法、生物反应器、色谱法、固相化学合成或生物传感器等。
