Muramyl dipeptide

Muramyl dipeptide (MDP) is a synthetic immunoreactive peptide, consisting of N-acetyl muramic acid attached to a short amino acid chain of L-Ala-D-isoGln. Muramyl dipeptide is an inducer of bone formation through induction of Runx2. Muramyl dipeptide directly enhances osteoblast differentiation by up-regulating Runx2 gene expression through MAPK pathways. Muramyl dipeptide indirectly attenuates osteoclast differentiation through a decreased RANKL/OPG ratio.

How to use

In Vitro:

Muramyl dipeptide (0.1-10 µg/mL; 24 hours) increases protein expression of Runx2 in a dose-dependent manner. Muramyl dipeptide (0.1-10 µg/mL; 6 hours) increases mRNA levels of Runx2 in a dose-dependent manner.

In Vivo:

Muramyl dipeptide (1.25 mg/kg; i.p.; twice) alleviates bone loss induced by osteoporosis.
