生物活性:
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 is a NLRP1 agonist.

体内研究:
Muramyl dipeptide (1.25 mg/kg;腹腔注射;两次) 减轻骨质疏松症引起的骨质流失。Animal Model:RANKL-induced osteoporosis model (Five-week-old C57BL/6 mice)
Dosage:1.25 mg/kg
Administration: i.p.; twice (RANKL-induced osteoporosis for 3 weeks and euthanized at 4 weeks)
Result:Significantly enhanced the trabecular bone volume (BV/TV) and trabecular number (Tb.N).

体外研究:
Muramyl dipeptide (0.1-10 μg/mL;24 hours) 以剂量依赖性方式增加 Runx2 的蛋白表达。Muramyl dipeptide (0.1-10 μg/mL;6 小时) 以剂量依赖性方式增加 Runx2 的 mRNA 水平。Muramyl dipeptide 通过降低 RANKL/OPG 比率间接减弱破骨细胞分化。
