| Description: | The H3 binding assay was/can be used to evaluate the ability of at least one compound in accordance with formula I, Ia, Ib, and/or Ic to inhibit [3H]-N-α-methylhistamine binding to CHO-K1 membranes expressing human histamine H3 receptors (full-length H3, the most prevalent brain isoform 445). In 200 μl 96-well SPA format, human H3 membranes (12.5 μg protein/well) and 1.4 nM [3H]-N-α-methylhistamine were/can be incubated with at least one compound in accordance with formula I, Ia, Ib, and/or Ic for 1.5 hrs to determine percent effect with respect to total (1% DMSO) and non-specific binding (10 μM imetit). Reproducibility of the assay is such that IC50 curves can be generated in singlicate. |
