title: Preparation and biological activity of some aminoacyl and peptidyl derivatives of 2'-amino-2'-deoxyuridine.
abstract: Several aminoacyl and peptidyl derivatives of 2'-amino-2'-deoxyuridine have been synthesized. 2'-Amino-2'-deoxyuridine (I) and 2'-N-glycyl-2'-amino-2'-deoxyuridine (IIIa) were condensed with N-Cbz blocked p-nitrophenyl esters of the appropriate amino acids to afford the protected aminoacyl and peptidyl nucleosides. Removal of the protecting groups gave the title compounds in good yields. The biological effects of these derivatives are discussed.
