[reaction: see text] A bicyclic 4-N-carbamoyldeoxycytidine derivative (1, dC(hpp)) geometrically locked was synthesized as a new fluorescent nucleobase. The hybridization properties of oligodeoxynucleotides containing dC(hpp) were investigated by use of T(m) analysis. It was found that dC(hpp) forms stable base pairs not only with the complementary guanine base, but also with the adenine base. Interestingly
[反应:见正文]合成了一种几何上锁定的双环4-N-氨基甲酰基脱氧胞苷衍生物(1,dC(hpp)),作为一种新的荧光核碱基。通过T(m)分析研究了含有dC(hpp)的寡聚脱氧核苷酸的杂交特性。发现dC(hpp)不仅与互补鸟嘌呤碱基而且与腺嘌呤碱基形成稳定的碱基对。有趣的是,仅当形成dC(hpp)-dG碱基对时,dC(hpp)的荧光才被抑制。
