Two different molecular switches, a spiropyran and a diarylethene, were attached synthetically to the 5-position of 2′-deoxyuridine. The diarylethene-modified nucleoside can be incorporated synthetically into DNA while preserving its characteristic photochromism.
在 2′-
脱氧尿苷的 5 位上合成连接了两种不同的分子开关,一种是螺
吡喃,另一种是二芳基
噻吩。经二芳基
噻吩修饰的核苷可合成到 DNA 中,同时保留其特有的光致变色性。
