RUNX1/ETO tetramerization-IN-1 is a small-molecule inhibitor that specifically targets NHR2 of RUNX1/ETO, effectively inhibiting the tetramerization process. With an EC50 value of 0.25 μM, this compound successfully restores gene expression that has been down-regulated by RUNX1/ETO. Furthermore, RUNX1/ETO tetramerization-IN-1 demonstrates promising anti-leukemic activity by inhibiting the proliferation of SKNO-1 cells dependent on RUNX1/ETO and significantly reducing RUNX1/ETO-associated tumor growth in a mouse model [1] [2] [3].

Ro5-3335 (CBFβ-Runx1 inhibitor II) is core binding factor (CBF) inhibitor; preferentially kills human leukemia cell lines with CBF fusion proteins (IC50 = 1.1 μM). Ro5-3335 represses RUNX1/CBFβ-dependent transactivation in reporter assays and inhibits transcriptional regulation by RUNX1 and CBFβ. Ro5-3335 also reduces the leukemia burden in a mouse model. Attenuates RUNX1-dependent hematopoiesis in zebrafish embryos. It also is a Tat antagonist and inhibits HIV-1 replication in vitro.

RUNX-IN-1, also known as Compound Conjugate 1, covalently attaches to RUNX-binding sequences, thereby preventing RUNX proteins from associating with their specific targets. This compound triggers p53-dependent apoptosis and suppresses the proliferation of cancer cells. Furthermore, RUNX-IN-1 has demonstrated efficacy in impeding tumor progression in PANC-1 xenograft mice [1].

Ro24-7429 is an effective and orally active antagonist of HIV-1 transactivator protein Tat and an inhibitor of a runt-related transcription factor 1. Ro24-7429 has anti-HIV, antifibrotic, and anti-inflammatory effects.

WUN40378 is compound first reported in PCT Int. Appl. (2019), WO 201909959, in which it was described as CBFβ-RUNX1 inhibitor. WUN40378 is very similar to Ro 5-3335 but with an F instead of Cl. WUN40378 is also analog of Ro 24-7429. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).

AI-4-57 Hydrochloride is a ligand to the CBFß. AI-4-57 Hydrochloride is a modest potency inhibitor of the binding of wildtype CBFß to the RUNX1 Runt domain.
