Preparation and antiviral properties of new acyclic, achiral nucleoside analogues: 1- or 9-[3-hydroxy-2-(hydroxymethyl)prop-1-enyl]nucleobases and 1- or 9-[2,3-dihydroxy-2-(hydroxymethyl)propyl]nucleobases

Acyclic, achiral nucleoside derivatives 1b-e of adenine, cytosine, 5-methylcytosine, and guanine, containing a 3-hydroxy-2-(hydroxymethyl)prop-1-enyl group on N-1 or N-9, have been prepared analogously to the previously described thymine derivative 1a. In contrast to the adenine and guanine derivatives, the cytosine derivative 9 was unstable, and was obtained in a low yield due to side reactions. These
类似地制备了腺嘌呤,胞嘧啶,5-甲基胞嘧啶和鸟嘌呤的无环非手性核苷衍生物1b-e,其在N-1或N-9上含有3-羟基-2-(羟甲基)丙-1-烯基。到前面描述的胸腺嘧啶衍生物1a。与腺嘌呤和鸟嘌呤衍生物相反,胞嘧啶衍生物9是不稳定的,并且由于副反应而以低收率获得。这些包括从碱基上裂解丙烯基和形成双环化合物。胸腺嘧啶衍生物尽管在中性条件下稳定,但同样在酸或碱的存在下进行可逆的环化反应(迈克尔加成反应)。5-甲基胞嘧啶衍生物在中性和碱性条件下稳定。其他4种含有2的核苷衍生物26a-d 同样已经制备了三个新的N-1或N-9上的3-二羟基-2-(羟甲基)丙基。所有化合物均被评估为抗HIV-1和HSV-1的抗病毒剂,但没有抗病毒活性。
