High-throughput screening for human galactokinase inhibitors.

ABSTRACT: Inherited deficiency of galactose-1-phosphate uridyltransferase (GALT) can result in a potentially lethal disorder called classic galactosemia. Although the neonatal lethality associated with this disease can be prevented through early diagnosis and a galactose-restricted diet, the lack of effective therapy continues to have consequences: developmental delay, neurological disorders, and premature ovarian failure are common sequelae in childhood and adulthood. Several lines of evidence indicate that an elevated level of galactose-1-phosphate (gal-1-p), the product of galactokinase (GALK), is a major, if not sole, pathogenic mechanism in patients with classic galactosemia. The authors hypothesize that elimination of gal-1-p production by inhibiting GALK will relieve GALT-deficient cells from
