drop-by-drop addition of Br2 water to dCyd (500 mg) at
0 ꢀC until the solution changed to a persistently light yel-
low color. To convert corresponding bromohydrin to 5-
OH-dCyd, 10% (v/v) 2,4,6-collidine was added and the
solution was stirred at room temperature for 2 days. The
product was purified by HPLC using the ODS column
with 5% methanol in water as the mobile phase, and dried
on a vacuum pump. For 5-Br-dCyd, bromination of dCyd
was carried out by the drop-by-drop addition of Br2 water
to dCyd (200 mg) at 0 ꢀC until the solution changed to a
persistently light yellow color. The solution was stirred
at room temperature for 1 day. The product was purified
by HPLC using the ODS column with 10% methanol in
water as the mobile phase, and dried on a vacuum pump.

The concentrations of the products were evaluated from
integrated peak areas on HPLC chromatograms detected
at 260 nm and the molecular extinction coefficients at
260 nm. The e260nm of 7400 Mꢀ1 cmꢀ1 was used for dCyd.
The e260nm values for 5-OH-dCyd and 5-Br-dCyd were
estimated to be 2970 and 3960 Mꢀ1 cmꢀ1, respectively,
from the integration of H10 proton signal and the HPLC
peak area detected at 260 nm relative to those of dCyd.
