Ethyl esters of alkanesulfonic acids, isethionic acid, trifluoromethanesulfonic acid, and 2, 2, 2-trifluoroethanesulfonic acid were synthesized and tested for inhibitory activity toward the growth of cultured leukemia L1210 cells. A quantitative correlation with the rate of hydrolysis and the capacity factor (partition property) was demonstrated by a multiple linear regression analysis; the more reactive and more lipophilic, the more cytotoxic they are. Interestingly, fluorine substitution on the alcoholic moiety resulted in remarkable deviations of the toxicity from those expected from the correlation found for the ethyl esters without fluorine substitution. Then, some fluorine derivatives of busulfan, a clinically used bifunctional sulfonate, were synthesized and tested. 2, 2-Difluoroethyl 2, 2, 2-trifluoroethanesulfonate was several times more cytotoxic than busulfan.
烷基磺酸乙酯、异硫羟酸、三氟甲磺酸和2,2,2-三氟乙磺酸的乙酯被合成并用于测试对培养的白血病L1210细胞生长的抑制活性。通过多元线性回归分析,证明了它们与水解速率和容量因子(分配性质)之间的量化相关性;越活泼、越亲脂性,它们的细胞毒性就越大。有趣的是,醇部分上的氟取代导致毒性显著偏离了预期,这种预期是基于不含氟取代的乙酯的相关性得出的。然后,合成了一些临床使用的双功能磺酸盐-白消安的氟化衍生物并进行了测试。2,2-二氟乙基2,2,2-三氟乙磺酸盐的细胞毒性比白消安高出数倍。
