TIC10 induces the expression of TNF-related apoptosis-inducing ligand (TRAIL) at 1-5 μM in a p53-independent manner. It is orally active, stable, and crosses the blood-brain barrier. The induction of TRAIL results from dual inhibition of Akt and ERK1/2 combined with nuclear translocation of the transcription factor FOXO3a. TIC10 suppresses the growth of orthotopic human glioblastoma multiforme tumors in mice.
7-Benzyl-4-(2-methylbenzyl)-1,2,6,7,8,9-hexahydroimidazo[1,2-a]pyrido[3,4-e]pyrimidin-5(4H)-one is used in biological studies for structure confirmation and pharmacophore reassignment for induction of immunosurveillance cytokine TRAIL in macrophages. The structure of this compound was misassigned for many years as H291055. The resolution of this issue was recently highlighted in Chemical and Engeneering News 92(23) 32 (2014).
