Biochem/physiol Actions

2-Acetyl-4-tetrahydroxybutyl imidazole (THI) is known to induce peripheral blood lymphopenia in rats. Studies in rats have also reported that THI can affect lymphocyte migration and degradation.
THI is an inhibitor of sphingosine-1-phosphate lyase and acts as an immunosuppressant.
THI is an inhibitor of sphingosine-1-phosphate lyase and acts as an immunosuppressant. Sphingosine-1-phosphate (S1P) lyase catalyzes the irreversible decomposition of S1P to hexadecanaldehyde and phosphoethanolamine. Reducing S1P lyase activity results in therapeutic levels of immunosuppression without the non-lymphoid lesions that result from synthetic S1P receptor agonists.

Preparation Note

THI is soluble in DMSO at a concentration that is greater than 5 mg/ml.

The human foot is highly derived relative to that of other hominoids and therefore a topic of intense research in paleoanthropology. While trabecular bone is thought to be highly plastic in response to habitual behavior, knowledge of how trabecular structure

Systemic neonicotinoids are commonly used in forest pest management programs. Senescent leaves containing neonicotinoids may, however, fall from treated trees into nearby streams. There, leaf-shredding invertebrates are particularly exposed due to their diet (feeding on neonicotinoid-contaminated leaves) or collaterally via
