Description of MRC37

MRC37 is a high-affinity TRIM21 ligand with a K d of 0.4 µM. MRC37 targets the IgG Fc-binding pocket in the PRYSPRY domain of TRIM21, mimics the "HHNY" epitope, and inhibits substrate-induced aggregation and activation of TRIM21 via competitive blockade of antibody binding. MRC37 effectively blocks TRIM21 -mediated antiviral immunity (such as adenovirus neutralization) and Trim-Away targeted protein degradation without cytotoxicity. MRC37 antagonizes TRIMTAC activity, and its multiple modification sites do not affect target binding, making it suitable as a degrader warhead for research on viral immunity and neurodegenerative diseases such as tauopathies [1].

In Vitro, MRC37 (0.4 μM; 48 h) binds to purified TRIM21 PRYSPRY domain with high affinity (0.4 μM) and exhibits no TRIM21-dependent cytotoxicity in wild-type RPE-1 cells at concentrations up to 20 μM for 48 h[1]. MRC37 (1 μM) monovalent ligand does not drive ternary complex formation between TRIM21 and H2B-mEGFP-Halo in RPE-1 cells, nor does it affect TRIM21 PRYSPRY binding when modified to generate TRIMTAC derivatives[1]. MRC37 (0.01-100 μM; 48 h) does not induce degradation of monomeric mEGFP-Halo, oligomeric CAV1-mEGFP-Halo, or oligomeric Cavin1-mEGFP-Halo in RPE-1 cells at concentrations up to 100 μM for 48 h[1]. MRC37 (50-100 μM; 15 h) inhibits TRIM21-mediated antiviral activity in HEK293T cells and TRIM21-dependent protein degradation in RPE-1 cells in a dose-dependent manner[1]. MRC37 (5 μM) does not degrade oligomeric Myd88 Myddosomes in stimulated cells, but can compete with TRIMTAC MRC414 to partially reverse inhibition of seeded tau aggregation in HEK293 reporter cells[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
