  摘要：

  描述了包含9-（2,3,4-三羟基丁基）腺嘌呤，A（C2）和A（C3）的寡核苷酸（ON）的合成和性质。含A（C2）的ON涉及链中的3'-> 4'和3-> 5'磷酸二酯键，而含A（C3）的ON具有3'-> 4'和2'- > 5'磷酸二酯键。发现将类似物A（C2）或A（C3）掺入ON中会显着降低ON / DNA双链体的热稳定性和热力学稳定性，但不会大大降低ON / RNA的热稳定性和热力学稳定性与ON / DNA双链体的情况相比。揭示了在ON / RNA双链体中，A（C2）的碱基识别能力大于A（C3）的碱基识别能力。

  Synthesis of 2′,5′-oligoadenylate analogs containing an adenine acyclonucleoside and their ability to activate human RNase L

  摘要：

  This paper described synthesis of 2',5'-oligoadenylate (2-5A) analogs containing the purine acyclonucleoside, 9[(2'S,3'R)-2',3',4'-trihydroxybutyl]adenine (2). The ability of the analogs to activate recombinant human RNase L was evaluated using 5'-(32) P-r(C11U2C7)(-3)' as a substrate. The EC50 value (the concentration of the 2-5A required to cleave half of the RNA) of the parent 2-5A tetramer 13 was 1.0nM, whereas those of the analog 14 incorporating 2 at the second position from the 5'-end and the analog 15 incorporating 2 at the third position from the 5'-end were 9.0 and 1.7nM, respectively. The analogs 14 and 15 were only 9- and 1.7-fold less potent than the parent 2-5A 13 itself, in RNase L activation ability. Furthermore, the oligodeoxynucleotide containing 2 was more resistant to nucleolytic hydrolysis by snake venom phosphodiesterase (a 3'-exonuclease) than the unmodified oligodeoxynucleotide. Thus, incorporation of an acyclonucleoside into 2-5A may be useful for developing an antiviral agent based on the 2-5A system. (C) 2004 Elsevier Ltd. All rights reserved.
