MMH1
Based on 1 Customer Validation
MMH1 is a novel BRD4 molecular glue degrader. MMH1 functions by recruiting the CUL4 DCAF16 ligase to the second bromodomain of BRD4 (BRD4 BD2). MMH1 binds to the JQ1-binding site of BRD4 BD2, acts as a template to covalently modify Cys58 of DCAF16, stabilizes the BRD4-DCAF16 ternary complex, and thereby promotes BRD4 degradation via the CRL4DCAF16 ubiquitin ligase pathway. Using BRD4 BD2 as a structural template, MMH1 covalently modifies Cys87 of GAK and induces the GAK-BRD4 BD2 interaction. Through its covalent mechanism, MMH1 exhibits sustained BRD4 degradation activity, and shows selective degradation activity for BRD4 BD2 over BRD4 BD1.

In Vitro
MMH1 (0.001-100 μM) potently promotes formation of the DDB1-DCAF16-BRD4BD2 ternary complex in a recombinant TR-FRET assay, with peak activity at 1 μM, while its non-reactive analog MMH1-NR (HY-157591) does not[1].
MMH1 (1-100 nM; 6 h, 0.1-10 μM; 16 h, 0.1 μM; 4 h pre-treatment followed by 20 h washout) potently degrades BRD4 in K562 cells, with a half-maximal degradation concentration (DC50,16h) of ~1 nM and maximal degradation (D_max,16h) of ~95%, while its non-reactive analog MMH1-NR does not induce BRD4 degradation[1].
MMH1 (1 μM; 4 h) induces a covalent-dependent interaction between GAK14-351 and BRD4_BD2 in 293T cells[1].

Result:Induced visible BRD4 degradation at 10 nM and 100 nM after 6 h, with degradation comparable to heterobifunctional degraders dBET6 and MZ1.
Induced robust BRD4 degradation across 0.1-10 μM after 16 h.
Exhibited sustained BRD4 degradation after washout, maintaining reduced BRD4 levels 20 h after a 4 h pre-treatment with 0.1 μM MMH1.
Achieved a half-maximal degradation concentration (DC50,16h) of 1 nM and maximal degradation (D_max,16h) of 95%.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
