Seventy eight N(3)-substituted derivatives of uridine (1), thymidine (2), 2'-deoxyuridine (3), 6-azauridine (4), 2',3'-O-isopropylideneuridine (5), and arabinofuranosyluracil (6) were synthesized and their antinociceptive effects were evaluated. N(3)-(2',4'-Dimethoxyphenacyl)uridine (1l), N(3)-(2',4'-dimethoxyphenacyl)2'-deoxyuridine (3l), and N(3)-(2',5'-dimethoxyphenacyl)arabinofuranosyluracil (6m) possessed 93, 86, and 82% of the

N3-Substituted derivatives of 2',3'-O-isopropylideneuridine (1) were synthesized and their pharmacological effects on the central nervous system (CNS) examined using mice. Methyl (2), ethyl (3), propyl (4), butyl (5), allyl (6), benzyl (7), o-, m-, p-xylyls (8, 9, 10), and alpha-phenylethyl
New nucleoside-phospholipid conjugates were synthesized based on 1,2-disubstituted glycerides and nucleosides. These contain rac-1-hexadecyl-2-palmitoyl(or 2-methylcarbamoyl)-sn-glycero-3-phosphate as the phospholipid component and 2',3'-didehydro-3'-deoxythymidine, 1-(Z-5-hydroxypentene-2-yl)thymine, or 2',3'-isopropylideneuridine as a nucleoside component. The conjugates were synthesized by three different ways: from rac-1-hexadecyl-2-acyl-sn-glycero-3-phospodichlorides, -3-phosphatidic acids
An improved procedure for the synthesis of N-benzoyl-2',3'-O-isopropylidene uridine via one-step selective N-benzoylation of 2',3' -O-isopropylidene uridine has been developed. An efficient synthetic route to N-benzoyl thymidine via initial tribenzoylation, followed by selective hydrolysis of the benzoates is also described.

The effect of pH on base release in the gamma-radiolysis of N2O-saturated solutions of a number of nucleosides (including uridine, 3-methyluridine, 2',3'-O-isopropylidene-uridine, and adenosine) has been investigated. For all these nucleotides, independent of the base or sugar moiety, base release
