included 4-[[(aryloyl)amino]methyl]phenoxy, 4-(arylacetamido)phenoxy, and 4-[[(arylamino)carbonyl]methyl]phenoxy. A total of 20 compounds were synthesized and tested. Structure-activity relationships are presented. Several of the new compounds were found to be strong allosteric effectors of hemoglobin. The two most active compounds are 2-[4-[[(3,5-dichloroanilino)carbonyl]-methyl]phenoxy]- 2-methylpropionic
制备了2-(芳氧基)-2-甲基丙酸的三个异构体系列,并研究了它们降低人血红蛋白A的氧亲和力的能力。异构体芳氧基包括4-[[[(芳基)氨基]甲基]苯氧基,4 -(芳基乙酰氨基)苯氧基和4-[[[(芳基氨基)羰基]甲基]苯氧基。总共合成和测试了20种化合物。提出了构效关系。发现几种新化合物是血红蛋白的强变构效应物。两种最具活性的化合物是2- [4-[[((3,5-二氯苯胺基)羰基]-甲基]苯氧基] -2-甲基丙酸和相应的3,5-二甲基衍生物。后两种化合物已在同一试验中与其他已知的强变构效应子进行了比较,并显示出更高的活性。与全血一起孵育时,这两种化合物的氧平衡曲线也都向右移动。新化合物可能在需要或受益于氧气供应逆转的临床或生物学领域(例如,缺血,中风,肿瘤放疗,储血,血液替代品等)中可能引起关注。它们在结构上还与几种市售的抗血脂药有关。
