Molibresib besylate 20+ Cited Publications GSK 525762C; I-BET 762 besylate	Epigenetic Reader Domain ERK	Cancer
Molibresib besylate (GSK 525762C; I-BET 762 besylate) is an orally active pan-BET inhibitor that targets and binds to BRD2, BRD3, BRD4 and BRDT. By competitively occupying acetylated lysine binding sites, Molibresib besylate disrupts the interaction between BET proteins and chromatin, thereby effectively inhibiting MYC expression and target gene transcription. Molibresib besylate exhibits broad antiproliferative activity, which not only inhibits cancer cell growth and induces growth arrest, but also downregulates mitosis-related genes and upregulates the level of p-ERK1/2. When combined with MEK inhibitors, Molibresib besylate shows a significant synergistic effect, reduces tumor burden in mouse models of leukemia, modulates the immune microenvironment and prolongs survival. Molibresib besylate is widely applicable to research related to acute myeloid leukemia, multiple myeloma, triple-negative breast cancer, small-cell lung cancer and various advanced refractory solid tumors .

BET-IN-18	Epigenetic Reader Domain	Cancer
BET-IN-18 (Compound 3) is a pan-BET bromodomain small-molecule inhibitor, with K_i values of 0.69 μM and 0.37 μM, and K_d values of 1.6 μM and 8.4 μM against BrdT (1) and Brd4 (1) bromodomains, respectively. BET-IN-18 potently and competitively inhibits the binding of the known BET inhibitor (+)-JQ1 (HY-13030) to Brd4 (1) and BrdT (1), with IC₅₀ values of 1.0 μM and 2.3 μM, respectively. BET-IN-18 also competitively inhibits the binding of acetylated histone substrates to Brd4 (1) (IC₅₀ = 0.90 μM). BET-IN-18 can be used in the research of multiple myeloma .

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
