TRPC6 inhibitor

Animal experiment:

Adult male (6 months old) spontaneously hypertensive rats (SHR) are treated on two consecutive days. On day one, the animals receive 1 mL/kg vehicle by oral gavage. After 24 h, rats receive either vehicle alone or are treated with 10 mg/kg SAR7334. Telemetric measurement of BP is performed. In brief, a telemetric device (TL11M2-C50-PXT PMP) is placed between the aorta and the vena cava and the catheter tip of the transmitter is inserted into the aorta. Systolic BP, diastolic BP and heart rate are acquired continuously at a sampling rate of 500 Hz and data are stored as 5 min averages. Mean arterial pressure is calculated from systolic and diastolic pressure and low-pass filtered using the fast Fourier transform function of the vendor software for better visualization of time-dependent BP variations. For statistical analysis, raw data are averaged over a 6 h period starting 2 h after application of vehicle or SAR7334. This interval corresponds to the maximal plasma levels of SAR7334. Baseline data are sampled over the same time interval on the day before treatment.
