Biological target:
Pyr6 blocks SOCE in thapsigargin treated, calcium depleted BRL-2H3 cells (IC50 = 0.49 μM), but has poor activity against carbachol-induced, TRPC3-mediated calcium entry in TRPC3-transfected HEK293 cells (IC50 = 18.46 μM).
In vitro activity:
Pyr6 exhibited a 37-fold higher potency to inhibit Orai1-mediated Ca(2+) entry as compared with TRPC3-mediated Ca(2+) entry and potently suppressed mast cell activation. Pyr6 is able to distinguish between TRPC and Orai-mediated Ca(2+) entry and may serve as useful tools for the analysis of cellular functions of the underlying Ca(2+) channels.
