BU-224 is a Putative I2 antagonist; and a high affinity ligand for the imidazoline I2 binding site (Ki = 2.1 nM). BU224 reverses cognitive deficits, reduces microgliosis and enhances synaptic connectivity in a mouse model of Alzheimer's disease.

BU224 hydrochloride is a selective and high affinity imidazoline I2 receptor ligand, with a Ki of 2.1 nM. BU224 hydrochloride is sometimes used as an I2 receptor antagonist. BU224 hydrochloride exerts neuroprotective effects, with anti-inflammatory and anti-apoptotic properties. BU224 hydrochloride improves memory in 5XFAD mice, enlarging dendritic spines and reducing Aβ-induced changes in NMDARs. BU224 hydrochloride can be used for Alzheimer's disease research[1][2][3].
