Description

General description

A cell-permeable, benzyl amine compound that can cross the blood-brain barrier and act as a selective antagonist of Sigma-2/progesterone receptor membrane component 1 (PGRMC1) receptor. Shown to competitively displace selective radioligand (3H-DTG) from homogenates of human B cell lines (K_i = 48 nM). Effectively blocks the effects of Abeta on membrane trafficking (EC₅₀ = 8.7 µM) and displaces Abeta binding on cultured neurons (EC₅₀ = 3.9 µM). It can also reverse Abeta oligomer-mediated trafficking deficits (EC₅₀ = 7.3 µM) and restore normal synaptic function and cognitive abilities in a murine model of Alzheimer′s disease (10 - 30 mg/kg. p.o. over a period of 5.5 months). Shown to be effective when added either 1 hour prior to or 1 hour after Abeta oligomer preparations.

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
