Selective uptake of nucleoside analogues by herpes simplex virus infected cells may serve as the basis for a specific non-invasive diagnostic test for herpes simplex encephalitis. We have examined the effect of acyclovir on the selective uptake of [131I] 1-(2'-fluoro-2'-deoxy-beta-D-arabinofuranosyl
The reaction of [2-14C]-2 ,4-bis-O-(trimethylsilyl)uracil (2) with ~-~-acetyl-~-0-benzoyl-2-deoxy-2-fluoro-~-D-arabinofuranosyl bromide (3) yielded the 3-O-acety1-5-0-benzoyl nucleos e 4 which was hydrolyzed with methanolic ammonia to afford [ 2-feC]-T-( 2-deoxy-2fluoro-p-D-arabinofuranosy1)uracil (
The synthesis of t h e title canpound (7) is described. [2-14C] cytosine (I) is treated with an aqueous mixture of sodium bisulfite and sodium sulfate at 8OoC for 30 rnin. The resulting solid is then treated with aqueous sodiun hydroxide and passed through a cation exchange colunn, producing [ Z-14C
