A high affinity 5-HT6 Receptor antagonist (pKi = 9.0). Good solubility (to 100mM in water or DMSO), oral availability, and penetrant to blood brain barrier. Over 200-fold selective for 5-HT6 receptors vs all receptors, ion channels and enzymes tested in Hirst et al. 2006 publication. Shows nootropic, antidepressant and axiolytic effects comparable to well-described drugs such as diazepam, and therefore has been proposed as novel treatment for schizoprenia and Alzheimer’s disease.Solubility:DMSO or H2OPrimary Target:5-HT6Primary Target Ki:1nMStorage and Stability:May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
