  • Patent number: 5945407
    Abstract: The present invention relates to the use of butyrate esters of threitol, alone or in combination with other agents, in pharmaceutical compositions and methods for increasing fetal hemoglobin and gamma globin in a patient. These methods are particularly useful in treating .beta.-hemoglobinopathies, such as sickle cell syndromes and .beta.-thalassemia syndromes. Compositions comprising butyrate esters of threitol, alone or in combination antiproliferative and differentiating agents are also useful in methods for inducing cell differentiation in malignant cells. These methods are useful in treating cancer, particularly the tetrabutyrate ester.
