Mifamurtide TFA (MTP-PE TFA) 是穆拉基二肽 (MDP) 的类似物，一种非特异性免疫调节剂，通过刺激激活巨噬细胞和单核细胞的免疫应答而发挥作用。Mifamurtide TFA 是一种孤儿药，是 NOD2 的特异性配体，用作胰岛素增敏剂。Mifamurtide TFA 具有用于骨肉瘤研究的潜力。

Mifamurtide TFA (MTP-PE TFA), an analog of the muramyl dipeptide (MDP), is a nonspecific immunomodulator by stimulating the immune response activating macrophages and monocytes. Mifamurtide TFA, an orphan drug, is a specific ligand of NOD2 used as an insulin sensitizer. Mifamurtide TFA has the potential for osteosarcoma research.

Mifamurtide TFA (MTP-PE TFA; 100 μM) induces a reduction of MG63 cells number when co-cultured with macrophages.
Mifamurtide TFA (100 μM) increases both the M1 polarization marker iNOS and the M2 polarization marker CD206 mRNAs; both pro-inflammatory (IL-1β, IL-6) and anti-inflammatory (IL-4, IL-10) cytokines. Mifamurtide TFA increases the iron transporter DMT1 protein.
L-mifamurtide TFA (5, 5000 nM; for 48 hours) alone has no direct effect on the proliferation rate of the two osteosarcoma cell lines MOS-J and KHOS in vitro or in vivo.
Mifamurtide TFA acts as a nonspecific immunomodulator by activating macrophages and monocytes related to the upregulation of tumoricidal activity and secretion of pro-inflammatory cytokines including tumor necrosis factor (TNF)-a, interleukin (IL)-1, IL-6, IL-8, IL-12, nitric oxide (NO), prostaglandin E2 (PGE2) and PGD2.

Mifamurtide TFA (MTP-PE TFA; 1 mg/kg; i.v.; twice per week for 4 weeks) causes a trend of diminished spontaneous lung metastasis dissemination.
Mifamurtide TFA (50 μg/mouse) improves glucose tolerance during endotoxemia in mice. Mifamurtide TFA (equivalent to 20 μg MDP; 4 times per week for 5 weeks) improves glucose tolerance in HFD-fed mice without altering body mass.
has not independently confirmed the accuracy of these methods. They are for reference only.
