The trans isomer of 2-(4-bromophenyl)-5-tert-butyl-2-thiono-1,3,2-dioxaphosphorinane competitively inhibited the specific binding of 35S-tert-butylbicycIophosphorothionate to rat brain membranes with an IC50 value of 0.52μm, and showed insecticidal activity against houseflies with an LD50 value of 2.4μg/fly. This compound and its analogues acted as noncompetitive GABAA receptor antagonists (NGRAs), and phosphorus-containing cyclohexane skeletons may prove useful for the design of novel NGRAs.
