several (methylsulfonyl)methanesulfonates that possess alkylating groups other than the 2-haloethyl groups. 2-Hydroxyethyl (methylsulfonyl)methanesulfonate was active against P388 leukemia (increases in lifespan, 66 and 94%), but was less effective than clomesone, which effects cures. The 3-chloropropyl and the propyl derivatives caused modest increases in lifespan. Therefore, several 2-chloroethyl α-substituted
2-氯乙基(甲基磺酰基)甲磺酸盐(氯米松)对某些实验性肿瘤非常有效,目前正在初步临床试验中。准备了两组类似物以进一步探索此类磺酸盐的抗癌活性。在磺酸盐基团上具有吸电子基团α的几种2-氯乙基磺酸盐;其中,在针对小鼠的P388白血病试验中,α-氯乙烷磺酸盐和(三氟甲基)-甲磺酸盐分别导致寿命增加45%和72%。第二组由具有除2-卤代乙基之外的烷基化基团的几种(甲基磺酰基)甲磺酸盐组成。2-羟乙基(甲基磺酰基)甲磺酸盐对P388白血病有活性(寿命分别增加66%和94%),但效果不如克罗美松,后者可治愈。3-氯丙基和丙基衍生物引起寿命的适度增加。因此,几种2-氯乙基α-取代的甲磺酸盐对P388白血病的疗效不如α-(甲基磺酰基)衍生物(氯美松),并且几种取代烷基(甲基磺酰基)甲磺酸的功效也较2-氯乙基衍生物(氯美松)低。 )。由甲磺酰氯简化了克罗美松的合成至一个操作步骤。以及几种取代的(甲基磺酰
