Menin-MLL Inhibitor 24 (compound A) oxalate, a menin-mixed-lineage leukemia 1 (menin-MLL) inhibitor, is utilized in cancer research [1].

BRD4 Inhibitor-28 (Compound 18), an orally active molecule, selectively inhibits the bromodomains of BRD4 (BRD4-BD1 and BRD4-BD2) with IC50 values of 15 and 55 nM, respectively. It also demonstrates inhibition of BRD2-BD1, BRD3-BD1, and BRDT-BD1 with IC50 values of 19, 25, and 68 nM, respectively. Furthermore, this compound exhibits anti-melanoma activity [1].

TCIP 1 is a small molecule in the category of transcriptional/epigenetic covalent inhibitor probes (TCIPs) that forms covalent bonds with molecules targeting BCL6 and BRD4. This compound facilitates cell death gene expression by directing endogenous cancer drivers or transcription factors to the promoters of these genes. Additionally, TCIP 1 exhibits a gain-of-function mechanism, displaying both cell and tissue specificity, and it establishes a ternary complex with BCL6 and BRD4. It counteracts BCL6's inhibitory effect on apoptosis gene expression, leading to the activation of apoptosis. Furthermore, TCIP 1 markedly suppresses MYC oncogene expression and curtails the proliferation of diffuse large B-cell lymphoma (DLBCL) [1].

BAZ2-ICR is an epigenetic chemical probe and it also is a potent, selective, cell active and orally active BAZ2A/B bromodomains inhibitor with IC50s of 130 nM and 180 nM, and Kds of 109 nM and 170 nM, respectively. BAZ2-ICR shows 10-15-fold selectivity for binding BAZ2A/B over CECR2 and >100-fold selectivity over all other bromodomains.

VTP50469 is a highly selective and orally active inhibitor of Menin-MLL interaction( Ki: 104 pM) and has potently anti-leukemia activity.
