    • This invention relates to novel methods of increasing the level of fetal hemoglobin (HbF) in a subject and methods of treating, preventing or ameliorating beta -globin or other HbF-related disorders by increasing the level of HbF in a subject in need of such treatment comprising administering one or more compounds of the formulae: (I) XCH2-CHX-CHX-C(=O)-O-Z, (II) CH3-CO-CH2-C(=O)-O-Z or (III) CH3-CH2-CO-C(=O)-O-Z, wherein X is H, or one of X only may be OH; Z is -CHR-O-C(=O)R', -CHR-O-C(=O)-O-R', or (IV); R is H, alkyl, aryl, arylalkyl; and R' is alkyl, aminoalkyl, aralkyl, aryl, alkoxy, aralkoxy and aryloxy, in which aryl by itself, and aryl in aralkyl, aralkoxy and aryloxy are each selected from the group consisting of phenyl, naphthyl, furyl, or thienyl, each of which is unsubstituted or substituted by at least one substituent selected from the group consisting of alkyl, alkoxy, or halogen; and pharmaceutically acceptable salts and prodrugs thereof.
    • 本发明涉及增加受试者胎儿血红蛋白(HbF)水平的新方法以及通过增加需要这种治疗的受试者中HbF水平来治疗,预防或改善β-珠蛋白或其他HbF相关疾病的方法 包括施用一种或多种下式的化合物:(I)XCH2-CHX-CHX-C(= O)-OZ,(II)CH3-CO-CH2-C(= O)-OZ或(III)CH3-CH2 -CO-C(= O)-OZ,其中X是H,或者X中的一个可以是OH; Z是-CHR-O-C(= O)R',-CHR-O-C(= O)-O-R'或(IV); R是H,烷基,芳基,芳基烷基; 和R'是烷基,氨基烷基,芳烷基,芳基,烷氧基,芳烷氧基和芳氧基,其中芳基本身和芳烷基,芳烷氧基和芳氧基中的芳基各自选自苯基,萘基,呋喃基或噻吩基,各自 其中未取代或被至少一个选自烷基,烷氧基或卤素的取代基取代; 及其药学上可接受的盐和前药。
