New photoaffinity ligand candidates were synthesized based on 5-t-butyl-2-(4-(substituted-ethynyl)phenyl)-1, 3-dithiane for the noncompetitive blocker site on the gamma-aminobutyric acid-gated chloride channel. Their half-maximal inhibition concentrations ranged from 4 to 32 nmol/L as measured by 4'-ethynyl-4-n-[2,3-³H₂]-propylbicycloorthobenzoate (³H EBOB) assay.
