series of 5'-sulfamoylated carbocyclic purinyl nucleosides was synthesized and tested for antitumor and antibacterial activities. The target compounds were formed by reacting the 2',3'-acetonide-protected carbocyclic nucleosides with sulfamoyl chloride, followed by deprotection. The agents were tested for cytotoxic activity against P388 mouse leukemia cells. Two compounds, 5'-sulfamoyl carbocyclic adenosine
合成了第一批5'-磺酰化碳环嘌呤核苷,并测试了其抗肿瘤和抗菌活性。通过使2',3'-丙酮化物保护的碳环核苷与氨磺酰氯反应,然后脱保护,形成目标化合物。测试了这些药剂对P388小鼠白血病细胞的细胞毒活性。5'-氨磺酰基碳环腺苷(2)和5-氨磺酰基-8-氮杂碳环腺苷(6)这两种化合物的IC50值分别低至62和15 nM。这些类似物抑制了P388细胞的蛋白质生物合成,并减慢了DNA和RNA的生物合成。没有一种靶标分子对大肠埃希氏菌具有如此强的抗肿瘤细胞效用。另外,在无细胞系统中 试剂2和6在兔网织红细胞裂解物中比在大肠杆菌中是更有效的蛋白质合成抑制剂。这些新的碳环衍生物在影响翻译中似乎比真核细胞对真核细胞具有一定的选择性。
