SB-423557

SB-423557 is an orally active calcium-sensing receptor (CaR) antagonist (IC₅₀=520 nM), precursor of SB-423562 (IC₅₀=73 nM). SB-423557 is well tolerated in human and increases plasma concentrations of exogenous parathyroid hormone (PTH) and stimulates bone formation.

Biological Activity

Description

IC₅₀ & Target

IC50: 520 nM (Calcium-sensing receptor)^[1]

In Vivo

SB-423557 (oral administration; 10, 30 or 100 μM/kg; once daily; 12 weeks) elicits transient increases in plasma concentrations of PTH, resulting in increased bone mass and strength in both vertebrae and long bones compared to that of OVX controls^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
