Based on 5 publication(s) in Google Scholar
MT-802 is a BTK PROTAC degrader. MT-802 degrades wild-type BTK (DC50 = 14.6 nM) and BTK mutants including E41K, C481S (DC50 = 14.9 nM), C481R, C481Y, C481T, C481F, L528W, and inhibits their Y223 phosphorylation. BI-4732 can be used for the study of Ibrutinib (HY-10997)-resistant chronic lymphocytic leukemia (CLL).

MT-802 shows binding affinity to BTK with an IC50 of 18.11 nM and to CRBN with an IC50 of 1.258 μM in TR-FRET-based binding assays[1].
MT-802 (0.1-10 μM, 24 h) degrades wild-type BTK and BTK mutants including E41K, C481S, C481R, C481Y, C481T, C481F, L528W, and inhibits their Y223 phosphorylation, but fails to degrade T474I mutant BTK in HEK293 cells with transient expression of BTK variants[1].
MT-802 (0.25-250 nM, 24 h) induces degradation of BTK in NAMALWA cells and induces equivalent degradation of WT BTK (DC50 = 14.6 nM) and C481S mutant BTK (DC50 = 14.9 nM) in WT BTK XLAs cells and C481S BTK XLAs cells, respectively[2].
MT-802 (0.01-10 μM, 24 h) degrades BTK and does not induce degradation of IKZF1 and IKZF3 transcription factors in primary cells from CLL samples[2].
MT-802 (1 μM, 0.0042-4 h) degrades WT BTK and C481S mutant BTK, and reduces the level of phosphorylated BTK (pBTK, Y223) in WT BTK XLAs cells and C481S BTK XLAs cells, respectively[2].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.17 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.17 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
