NPS-2143 (SB-262,470A) is a calcilytic drug which acts as an antagonist at the Calcium-sensing receptor (CaSR), and consequently stimulates release of parathyroid hormone. ^[1] Calcilytic drugs have been researched as potential treatments for osteoporosis, and as the first such compound developed, NPS-2143 is still widely used in research into the CaSR receptor as well as design of newer calcilytic agents. ^{[2] [3] [4]}
