Synonyms: compound 33 [PMID: 29470065] | VUF 14862 | VUF-14862
Compound class: Synthetic organic
Comment: VUF14862 is a bidirectional photo-switchable histamine H3 receptor antagonist based on the structure of compound 3a [PMID: 18606542] [1]. The chemical structure shown here is the photo-activated isomer that binds the H3 receptor under UV illumination. VUF14862 binding is 'switched-off' by UV light. VUF14862 swiftly and reversibly photoisomerizes (via trans/cis conversion) and is suitable for spatiotemporal studies of H3 receptor signaling. See also VUF14738, which operates in the opposite direction.
