THI (94944-70-4) was identified as a biologically active impurity in caramel food coloring.1 It is a potent inhibitor of sphingosine-1-phosphate (S1P) lyase.2 It disrupts lymphocyte egress from lymphoid tissue by interfering with S1P gradients.3,4 The novel immunomodulatory activity of THI and its biochemical mechanism may represent a new target for the development of new generation of immunosuppressants.5
