24, 25, 28, 29, 31, and 34 were determined using EPR and/or UV methods. A predictive design pattern was observed, with the most active drug (34) possessing some hydrophobic property (log P = 1.24), followed by 13 (log P = 1.87) and 14 (log P = 1.81) as the more active drugs with higher hydrophobicity than 34. The clinical drugs streptozotocin (18) and chlorozotocin (31) were distinctly hydrophilic and
自旋标记的葡萄糖亚硝基脲13-16,链脲佐菌素(18),氯唑菌素(31),半乳糖基24和甘露糖基28的链脲佐菌素类似物及其四-O-乙酰基衍生物25和29,MCNU(Cymerin,34)和葡萄糖胺(21)已合成并在体内评估了其对鼠淋巴细胞性白血病P388的抗癌活性。化合物13-16、18、24、28、31和34的活性增长寿命(%ILS)在33%至603%之间,而21、25和29种化合物则无活性(%ILS = 9至10)。在30天后,所有用活性最高的化合物(13、14和34)以20 mg / kg治疗的CD2F1雄性小鼠均存活,而所有经临床链脲佐菌素(18)和经临床测试的氯佐霉素(31)治疗的小鼠均被淘汰。化合物13-16、18、31,进一步评估了34和34的抗淋巴白血病L1210的抗肿瘤活性。与CCNU(1)和自旋标记SLCNU(3)相比,化合物13和34在第60天的%ILS值分别为557
