Sample solution is provided at 25 µL, 10mM.
R 568 hydrochloride is a kind of calcimimetic agent which can changed the structural conformation of the calcium-sensing receptor (CaSR) and stereo-selectively increased its sensitivity to extracellular Ca2+ [1]. R 568 hydrochloride, as a phenylalkylamine derivative of calcimimetics, has been subjected to clinical trials and shown a dose-dependent decrease in the levels of parathyroid hormone (PTH) [2].
R 568 hydrochloride (1μM; 4h) significantly upregulated IL-8 expression in HT29CaSR-GFP cells; R 568 hydrochloride (1μM; 4h) significantly upregulated the expression of COX-2 and PGES-1 [3].
R 568 hydrochloride (20μmol/kg; 8weeks; s.c.) decreased the blood urea nitrogen (BUN) levels of Sprague-Dawley (SD) rats with uremic; R 568 hydrochloride (20μmol/kg; 8weeks; s.c.) suppressed the increase in parathyroid gland volume of SD rats with uremic [4]. R 568 hydrochloride (3, 30mg/kg; 16d; p.o.) reduced serum PTH levels of SD rats which subjected to a partial nephrectomy [5]. R 568 hydrochloride (0.5, 1.0, 2.5 and 5.0mg/kg; 30min; i.v.) decreased plasma Ca2+ concentration in Wistar rats [6].

| Cell experiment [1]: | |
Cell lines | HT29 cells |
Preparation Method | HT29 cells were lentivirally transduced to stably express the CaSR fused to GFP (HT29CaSR-GFP), and when the cells reached 80% confluency, they were treated with vehicle (H2O) or 1µM R 568 hydrochloride for 4h. |
Reaction Conditions | 1μM; 4h |
Applications | R 568 hydrochloride significantly upregulated IL-8 expression in HT29CaSR-GFP cells. |
| Animal experiment [2]: | |
Animal models | Male Sprague-Dawley rats |
Preparation Method | Rats were rendered uremic using a two-step partial ligation procedure and then received continuous subcutaneous infusion (20μmol/kg) of R 568 hydrochloride for 8weeks. |
Dosage form | 20μmol/kg; 8weeks; s.c. |
Applications | R 568 hydrochloride suppressed the increase in parathyroid gland volume of uremic rats by decreased the cell volume and cell number of gland. |
