Imidazo[1,2-a]pyridine derivatives as inhibitors of TNF-alpha expression in T cells.


PMID 18035545

Abstract

Novel hexahydroimidazo[1,2-a]pyridines prepared by the addition of ethyl (1-benzylimidazolidin-2-ylidene)acetate (2) to the fungal metabolite podoscyphic acid (1a) and esters of 1a have been evaluated for their ability to inhibit the inducible TNF-alpha promoter activity in T cells. The methyl ester 3b is the most potent, inhibiting the TNF-alpha driven reporter gene expression in Jurkat T cells with an IC(50)-value of 2.0 microg/ml (3.6 microM). In addition, compound 3b inhibited the inducible TNF-alpha production in the myelomonocytic U937 cells with an IC(50)-value of 4.6 microM.
