  Synthesis and Fluorescent Properties of Bi- and Tricyclic 4-N-Carbamoyldeoxycytidine Derivatives

  摘要：

  [GRAPHICS]New bi- and tricyclic deoxycytidine derivatives (dC(hpd), dC(mpp), dC(tpp), dC(ppp)) were synthesized as analogues of a fluorescent nucleoside, dC(hpp), previously reported. The carbamoyl group of dC(hpd) and the 5-position of the cytosine ring are bridged via an ethylene linker so that the modified group forms a nonplanar structure with the cytosine ring. The fluorescent study of dC(hpd) indicated that the coplanar structure between the carbamoyl group and the cytosine ring is of importance. N-Methylation of the carbamoyl group (dC(mpp)) weakened the intensity of the fluorescence of dC(hpp), and the derivative (dC(tpp)), which had a thiocarbamoyl group, lost its fluorescent property. Moreover, addition of a pyrrolo-ring (dC(ppp)) to dC(hpp) enhanced the intensity of fluorescence, and an emission light was observed with a marked Stokes shift of 120 nm.
