The photophysical properties of 11 substituted 5‐(benzothiazol‐2‐yl)‐2′‐deoxyuridine derivatives and oligodeoxyribonucleotides (ODNs) containing dbtU are described. The fluorescence properties of the ODNs containing 16 combinations of 5′‐XbtU‐3′ and 5′‐btUY‐3′ were compared, and dbtU was found to be a very promising new fluorescent analogue while showing low sensitivity to its microenvironment in DNA
描述了11个含d bt U的5–(苯并噻唑-2-基)-2 -'-脱氧尿苷衍生物和寡脱氧核糖核苷酸(ODN)的光物理性质。比较了包含5'-X bt U-3'和5'- bt UY-3'的16种组合的ODN的荧光特性,发现d bt U是一种非常有前途的新荧光类似物,但对Dbt U的敏感性较低。它在DNA中的微环境。
