Abstract: Previously, we have described 5-((4-methoxy-phenyl)-trans-vinyl)-2'-deoxy-uridine, 6, as a fluorescent uridine analogue exhibiting a 3000-fold higher quantum yield (Φ 0.12) and maximum emission (478 nm) which is 170 nm red-shifted as compared to uridine. Here, we utilized 6 for preparation of labeled oligodeoxynucleotide (ODN) probes based on MS2 and cyclin D1 (a known breast cancer mRNA marker) sequences. Cyclin D1-derived labeled-ssODN showed a 9.5-fold decrease of quantum yield upon duplex formation. On the…
