General description
2-Acetyl-5-tetrahydroxybutyl imidazole (THI) is an inhibitor of sphingosine-1-phosphate lyase (S1P lyase).
Sphingosine-1-phosphate (S1P) lyase catalyzes the irreversible decomposition of S1P to hexadecanaldehyde and phosphoethanolamine. 2-Acetyl-5-tetrahydroxybutyl imidazole (THI) is an inhibitor of S1P lyase. Because S1P lyase is primarily expressed in lymphatic tissue, treatment of mice with THI (50 μg/ml in drinking water) increases lymphoid tissue S1P concentrations 100-fold, reducing lymphocyte egress from thymus and peripheral lymphoid organs. The resulting lymphopenia is reversible following cessation of THI treatment. Reducing S1P lyase activity results in therapeutic levels of immunosuppression without the non-lymphoid lesions that result from synthetic S1P receptor agonists.
Biochem/physiol Actions
2-Acetyl-5-tetrahydroxybutyl imidazole (THI) can block S1P lyase in vivo and up-regulates circulatory and tissue S1P levels. It has the ability to repress dystrophic muscle degeneration.
