Biological Activity
SAR7334 hydrochloride is a potent and specific TRPC6 inhibitor, inhibiting TRPC6 currents with IC50 of 7.9 nM.
In Vitro
SAR7334 inhibits TRPC6, TRPC3 and TRPC7-mediated Ca2+ influx into cells with IC50s of 9.5, 282 and 226 nM[1][2][3], whereas TRPC4 and TRPC5-mediated Ca2+ entry is not affected. SAR7334 (1 μM) results in a major block of the Ang II-evoked calcium influx in the podocytes[1]. SAR7334 (1 μM) has negligible effect on SOCE[2]. SAR7334 dose-dependently reduces TRPC6 currents with an IC50 of 7.9 nM. SAR7334 (100 nM) substantially reduces TRPC6 currents[3].
In Vivo
SAR7334 (10 mg/kg, p.o.) suppresses TRPC6-dependent acute HPV in isolated perfused lungs from mice. SAR7334 demonstrates that it is suitable for chronic oral administration. In an initial short-term study, SAR7334 does not change mean arterial pressure in spontaneously hypertensive rats (SHR)[3].
