involved in DNA, RNA and protein syntheses, and in de novo and salvage pyrimidine and purine syntheses. Investigations were performed in vitro on human cervix carcinoma cells (HeLa). BMsU displayed inhibitory effects on DNA and RNA syntheses in HeLa cells after 24 h of treatment. De nova biosynthesis of pyrimidine and purine was also affected. Antitumor activity of BMsU is closely associated with its inhibitory
5-bromo-1-mesyluracil (BMsU) 4 的大规模制备得到了优化。BMsU 是通过甲硅烷基化 5-溴尿嘧啶和 MsCl 在乙腈中缩合或通过 5-溴尿嘧啶与 MsCl 在吡啶中反应合成的。通过 1-甲磺酰尿嘧啶的溴化得到相同的产物。本研究的目的是阐明 BMsU 对参与 DNA、RNA 和蛋白质合成以及从头和挽救嘧啶和嘌呤合成的肿瘤细胞酶的生物合成活性的影响。对人子宫颈癌细胞 (HeLa) 进行了体外研究。BMsU 在处理 24 小时后对 HeLa 细胞中的 DNA 和 RNA 合成显示出抑制作用。嘧啶和嘌呤的 De nova 生物合成也受到影响。BMsU 的抗肿瘤活性与其对在肿瘤细胞代谢中起重要作用的酶的抑制活性密切相关。还研究了 BMsU 的体内抗肿瘤活性。研究中使用的模型是移植到 CBA 小鼠右腿大腿的小鼠间变性乳腺癌。以 50 mg/kg 的剂量给药 BmsU 实现了肿瘤生长时间的显着缩短。

Conformational chirality and chiral crystallization of N-sulfonylpyrimidine derivatives
1-(1-naphthylsulfonyl)thymine (6) were prepared by the condensation reaction of silylated pyrimidine derivatives with selected sulfonyl chlorides in acetonitrile. Some members of the series showed unexpected crystal properties as a consequence of their conformational chirality in the solid state. Compounds 1 and 5 exhibited chiral crystallization, which was, in the case of 1, accompanied by the formation of racemically
