Background

NPS-2143 is a novel and selective antagonist of CaSR (Ca2+-sensing receptor) with the EC50 value of 4.27mM for [Ca2+]o [1].

Calcilytics NPS-2143 has been reported to diminish the sensitivity of the CaSR for [Ca2+]o, resulting in an attenuated signal transduction in vitro and increased secretion of PTH in vivo. In addition, The EC50 values of NPS-2143 are 4.27, 1.56, 1.61, 2.46, 2.07 and 3.15mM for the wild-type CaSR, mutant CaSR (T151R, P221L, E767Q, G830S, and A844T), respectively. Apart from these, in HEK 293T cells expressing CaSR, NPS-2143 has been revealed to inhibit the [Ca2+]o-induced cytosolic calcium signal in a concentration-dependent manner [1].
