描述 | Calcium-sensing receptor (CaSR), which belongs to the G protein-coupled receptor superfamily, is responsible for the regulation of systemic Ca2+ metabolism. Cinacalcet hydrochloride is a calcimimetic that allosterically increases the sensitivity and responsiveness of CaSR to Ca2+. It activates the wild-type CaSR signaling in cellular proliferation and PI hydrolysis assays with pEC50 values of 7.6 and 7.3, respectively[1]. When primary cultured human parathyroid cells were incubated with 0.5 mM extracellular Ca2+, cinacalcet hydrochloride from 0 – 1000 nM additionally suppressed the secretion of parathyroid hormone at a dose-dependent manner[2]. Cinacalcet hydrochloride at 30 – 1000 nM had no effect on osteoclastic formation or resorption in osteoclastic cells cultured in calcium-containing medium with the concentration of 1.6 or 6.1 mM[3]. Oral administration of primary hyperparathyroidism mice with 1 mg/g cinacalcet hydrochloride for 10 days led to significantly reduced levels of parathyroid and Ca in serum. The uptake of 5-Bromo-2’-deoxyuridine was also significantly decreased in mice following the administration of cinacalcet hydrochloride compared to the untreated ones[4]. | ||
作用机制 | Cinacalcet hydrochloride cooperates with Ca2+ to activate CaSR via interacting with its transmembrane domain[1]. |
