Muramyl dipeptide (MDP) 是合成的免疫反应肽,由 N-乙酰壁酸与 L-Ala-D-isoGln 的短氨基酸链相连。它通过MAPK 途径上调 Runx2 基因表达,直接促进成骨细胞分化,通过降低 RANKL/OPG 比值间接抑制破骨细胞分化。它是通过Runx2诱导骨形成的诱导因子,也是NLRP1激动剂。

产品描述 | 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 indirectly decreases osteoclast differentiation through a decreased RANKL/OPG ratio. Muramyl dipeptide directly increases osteoblast differentiation by up-regulating Runx2 gene expression through MAPK pathways. Muramyl dipeptide is an inducer of bone formation through the induction of Runx2 . |
体外活性 | Muramyl dipeptide 以剂量依赖的方式增加 Runx2 蛋白表达 (0.1-10 μg/mL; 24小时)[1],同时也在剂量依赖的方式下提高了 Runx2 的 mRNA 水平 (0.1-10 μg/mL; 6小时)[2]。此外,Muramyl dipeptide 通过降低 RANKL/OPG 比例间接抑制了破骨细胞的分化[2]。 |
体内活性 | Muramyl dipeptide 可用于动物建模以建立败血症模型。Muramyl dipeptide (1.25 mg/kg;腹腔注射;两次)缓解由骨质疏松症引起的骨质流失[2]。 |
