Compounds of the general structural formula: ##STR1## wherein X, Y and Z may each be CH.sub.2, NH, or O, R.sub.2-6 are either hydrogen, halogen, or a substituted or unsubstituted C.sub.1, C.sub.2, or C.sub.3 alkyl group and these moieties maybe the same or different, or alkyl moieties of aliphatic or aromatic rings incorporating two of the R.sub.2-6 sites, R.sub.7-8 are hydrogen, methyl, or ethyl groups and these moieties may be the same or different, or alkyl moieties as part of an aliphatic ring connecting R.sub.7 and R.sub.8, and R.sub.9 is a hydrogen, loweralkyl such as methyl, ethyl or propyl, or a salt cation such as sodium, potassium, or ammonium are useful for right-shifting hemoglobin towards a low oxygen affinity state. The compounds are capable of acting on hemoglobin in whole blood. In addition, the compounds can maintain the oxygen affinity in blood during storage and can restore the oxygen affinity of outdated blood.
通用结构式为:## STR1 ##
其中X、Y和Z可以分别是CH.sub.2、NH或O,R.sub.2-6是氢、卤素或取代的或未取代的C.sub.1、C.sub.2或C.sub.3烷基,这些基团可以相同或不同,或者是包含R.sub.2-6位点中的两个烷基的脂肪族或芳香族环的烷基基团,R.sub.7-8是氢、甲基或乙基基团,这些基团可以相同或不同,或者是作为连接R.sub.7和R.sub.8的脂肪环的烷基基团,R.sub.9是氢、较低的烷基,例如甲基、乙基或丙基,或盐基阳离子,例如钠、钾或铵,对于将血红蛋白向低氧亲和力状态右移很有用。这些化合物能够作用于全血中的血红蛋白。此外,这些化合物可以在贮存期间维持血液中的氧亲和力,并可以恢复过时血液的氧亲和力。
