MRS2693 ammonium
MRS2693 ammonium is a selective P2Y6 receptor agonist. MRS2693 ammonium exerts biological effects by activating the Gq-coupled P2Y6 receptor, the ERK1/2 pathway, and the P2RY6-PLCB3-CAMKK2-PRKAA1-ULK1 signaling cascade. MRS2693 ammonium attenuates TNFα-induced NF-κB activation, stabilizes XIAP via AKT-mediated phosphorylation, induces autophagy, and reactivates PRKAA1. MRS2693 ammonium can be used in research on diseases including skeletal muscle ischemia/reperfusion injury, TNFα-induced skeletal muscle apoptosis, chronic myelomonocytic leukemia, colorectal cancer, and dry eye disease.

MRS2693 ammonium (10-30 μM; 4 h-4 days) restores autophagy and normal differentiation of primary CD14+CD24- monocytes from a CMML patient co-cultured with CD14-CD24+ immature granulocytes, via reactivation of PRKAA1, while 10 μM MRS2693 ammonium partially increases PRKAA1 expression[2].
MRS2693 ammonium (1.5 μM; 15 min pre-incubation; continued during 4 h TNFα/CHX treatment and subsequent 16 h incubation) protects HT-29 colon carcinoma cells from TNFα-induced apoptosis by stabilizing XIAP via AKT-mediated phosphorylation, resulting in reduced PARP cleavage[3].
MRS2693 ammonium (1.5 μM; 30 min pre-incubation; continued during 24 h 5-FU treatment) induces resistance to 5-FU cytotoxicity in mouse CRC-derived tumoroids, preserving both tumoroid viability and proliferative cell activity[3].

-
Cell Line:mouse skeletal C2C12 myoblasts/myotubes
-
Concentration:0.1-100 nM (apoptosis assay); 10 nM (PKC expression analysis; ERK1/2 activation analysis; NF-κB attenuation analysis)
-
Incubation Time:4 h (apoptosis assay, prior to medium change, total 20 h post-TNFα exposure); 20 min (PKC expression analysis); null (ERK1/2 activation analysis); null (NF-κB attenuation analysis)
-
Result:Protected C2C12 cells against TNFα-induced apoptosis in a concentration-dependent manner between 0.1 and 10 nM, with protection diminished at 100 nM.
Provided 50-60% protection against TNFα-induced cell death in 5 and 7 day old C2C12 cultures at 10 nM and 100 nM.
Increased phosphorylated ERK1/2 levels by 3.4-fold at 10 nM.
Increased PKCθ expression after 20 min at 10 nM.
Attenuated the marked increase in NF-κB expression induced by 4 h TNFα exposure at 10 nM.
Showed no effect on cell death in the absence of TNFα, and only slightly increased NF-κB levels when used alone.
Had protective effects completely blocked by pre-incubating cells with 10 μM MRS2578 for 20 min at 10 nM.
