The reaction of 1H-pyrazolo[3,4-d]pyrimidin-4,6-dithione 11 with compounds 12a-c produces ethyl alpha-[6-(1'-carboethoxyalkylthio)-1 H-pyrazolo[3,4-d]pyrimidin-4-yl]thioalkylates 13a-c, respectively. These heterocycles were alkylated, separately, with alkylating agents 14, 15, and 16 to afford, predominately, the N(1)-acyclic nucleosides (17-19)a-c, which were deprotected to give the desired products

Abstract The chemical synthesis and biological evaluation of some acyclic α-[6-(1′-carbamoylalkylthio)-1H-pyrazolo[3,4-d]pyrimidin-4-yl]thioalkylamide nucleosides are described.
Several N 1 -(2-hydroxyethoxy)methyl, (4-hydroxybutyl) and (2,3-dihydroxy-1-propoxy)methyl-C 4 ,C 6 -disubstituted-1H-pyrozolo[3,4-d]pyrimidines were synthesized. Some of them were evaluated against herpes simplex virus 1 and 2 replications in E 6 SM cells.
几种 N 1 -(2-羟基乙氧基)甲基、(4-羟基丁基)和(2,3-二羟基-1-丙氧基)甲基-C 4 ,C 6 -二取代-1H-吡唑并[3,4-d]嘧啶是合成的。其中一些针对 E 6 SM 细胞中的单纯疱疹病毒 1 和 2 复制进行了评估。

A useful route to obtain trisubstituted pyrazolo[3,4-d]pyrimidines 14–17 is described. Those later were coupled with the alkylating agents 18–20 as in ACV, HBG, and iso-DHPG to give, after deprotection, the desired acylonucleosides 33–44. Almost all of the new compounds were evaluated for their inhibitory effects against the replication of various DNA viruses in culture.
