Mifamurtide TFA  (Synonyms: MTP-PE TFA; L-MTP-PE TFA; CGP 19835 TFA)

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 is a specific ligand for NOD2 and acts as an insulin sensitizer. Mifamurtide TFA has potential for use in rare disease and osteosarcoma research^[1][2][3].

Mifamurtide TFA (MTP-PE TFA; 100 µM) induces a reduction of MG63 cells number when co-cultured with macrophages^[3].
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^[3].
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^[1].
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^[3].

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^[1].
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^[2].
