A PTHrP analog that builds bone through selective PTH1 receptor signaling.
Also known as: Tymlos
Part of the Foundational & therapeutic peptides cluster
Overview
Abaloparatide is a synthetic 34-amino-acid analog sharing about 76% homology with parathyroid hormone-related protein (1-34). It selectively activates the PTH1 receptor to stimulate bone formation and is an approved anabolic therapeutic for osteoporosis at high fracture risk. This page is educational and not medical advice.
Source & context
Biological / chemical source: Synthetic 34-amino-acid analog of PTHrP(1-34)
Primary research or clinical context: Approved for osteoporosis at high fracture risk
Anabolic bone action
Like teriparatide, abaloparatide uses intermittent PTH-receptor stimulation to favor bone building over resorption. Its PTHrP-based sequence is thought to bias signaling toward a transient receptor conformation, a design intended to maximize the anabolic window.
Relationship to teriparatide
Abaloparatide is closely related to the PTH(1-34) fragment teriparatide but differs in sequence and receptor kinetics. Comparing the two is a common way to illustrate how small sequence changes tune the balance of bone formation and resorption.
