Pyr3 是一种选择性瞬时受体电位经典通道 3 抑制剂。 Pyr3 以剂量依赖性方式抑制 TRPC3 介导的 Ca2+ 内流 (IC50 = 700 nM)。

Pyr3 is a selective transient receptor potential canonical channel 3 inhibitor. Pyr3 inhibits TRPC3-mediated Ca2+ influx in a dose-dependent manner(IC50 = 700 nM).

Pyr3 becomes apparent at 0.3 μM and is almost complete at 3 μM. Ca2+ influx is inhibited by Pyr3 in cells co-expressing TRPC3 plus TRPC6 but not in cells co-expressing TRPC1 plus TRPC5. The Ang II-induced NFAT translocation is suppressed by Pyr3 (IC50 = 0.05 μM), but weakly by Pyr2 (IC50 = 2 μM) in a concentration-dependent manner[1].
