activities were investigated. Alkylation of cytosine with (E)-1,4-dichloro-2-butene gave chloro derivative 2f, which was hydrolyzed to alcohol 2h. Cytosine, adenine, 2-amino-6-chloropurine, thymine, and (Z)-1,4-chloro-2-butene gave compounds 4c-f, which, after hydrolysis, afforded alcohols 4a, 4b, 4g, and 4h. Alkenes 4d and 4e were cyclized to heterocycles 12 and 13. Alkylation of 2,6-diaminopurine with
制备了一系列核苷的不饱和类似物,并研究了它们的细胞毒性,抗肿瘤和抗病毒活性。用(E)-1,4-二氯-2-丁烯烷基化胞嘧啶,得到氯衍生物2f,将其水解成醇2h。胞嘧啶,腺嘌呤,2-氨基-6-氯嘌呤,胸腺嘧啶和(Z)-1,4-氯-2-丁烯得到化合物4c-f,水解后得到醇4a,4b,4g和4h。烯烃4d和4e环化成杂环12和13。2,6-二氨基嘌呤与1,4-二氯-2-丁炔的烷基化产生氯代衍生物6a,后者被水解成醇6b。6b的烯丙基异构化得到化合物5c。氯衍生物2e-g,4c-f,5d和6c-e以及嘧啶氧杂环戊烯9c和9d是IC50 10-100 microM的鼠白血病L1210的缓效抑制剂。最活跃的是类似物4c,4d,4e,和6e(IC50 10-20 microM)。相应的羟基衍生物的活性较小。用化合物4c,4d,6e,9c和9d抑制大分子合成的顺序如下:DNA大于RNA大于或等于蛋白质。四种
