CBFβ Inhibitor (5-Ethyl-4-(4-methoxy-phenyl)-thiazol-2-ylamine) is a cell-permeable CBFβ inhibitor and inhibits its association with Runx1.

Mefenidil (McN-2378), a selective cerebral vasodilator, was shown to increase CBF in healthy brains without stimulating O2 uptake in a dog anesthesia model.

Regadenoson (CVT-3146) is an adenosine derivative and selective A2A adenosine receptor agonist with coronary vasodilating activity. Upon administration, regadenoson selectively binds to and activates the A2A adenosine receptor, which induces coronary vasodilation. This leads to an increase in coronary blood flow and enhances myocardial perfusion. Compared to adenosine, regadenoson has a longer half-life and shows higher selectivity towards the A2A adenosine receptor. This agent is a very weak agonist for the A1 adenosine receptor and has negligible affinity for the A2B and A3 adenosine receptors.

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.

AI-10-49 is a selective inhibitor of the binding of CBFβ-SMMHC to RUNX1 with IC50 of 260 nM.

AI-10-47 (1H-Benzimidazole, 2-(2-pyridinyl)-6-(trifluoromethoxy)-AI-10-47) is a small molecule inhibitor of CBFβ-RUNX binding(IC50 : 3.2 μM).

Iodoantipyrine (Arthripur) is a commonly-used indicator and is used to evaluate in rats by measuring torcular venous efflux after systemic injection of the indicator under conditions of normal and high CBF.

HDAC-IN-38 is a potent inhibitor of HDAC. HDAC-IN-38 has similar micromolar inhibitory effects on HDAC1, 2, 3, 5, 6 and 8, and also increases histone acetylation levels (H3K14 or H4K5). HDAC-IN-38 increases cerebral blood flow (CBF), reduces cognitive impairment and improves hippocampal atrophy.
