Biological Activity for AC 1903

AC 1903 is a selective TRPC5 blocker (IC50 = 13.6 μM). Also displays weak inhibition at TRPC4 (IC50 >100 μM) but not TRPC6. Exhibits no effect against a standard panel of profiling kinases. Blocks TRPC5 channel activity in glomeruli of proteinuric rats. Suppresses severe proteinuria and prevents podocyte loss in a transgenic rat model of focal segmental glomerulosclerosis (FSGS).
