The actions of the polychlorocycloalkane insecticide heptachlor, and its epoxide metabolite, were examined on GABA receptors in insects and vertebrates.

Br J Pharmacol. 1997 Aug;121(7):1496-505.

A variety of gamma-aminobutyric acid (GABA) receptor convulsants, including the insecticides heptachlor (IC50, 35 +/- 3 nM) and dieldrin (IC50, 93 +/- 7 nM), displaced [3H]-BIDN from rootworm membranes.

Lindane and the cyclodienes dieldrin, endrin, heptachlor-epoxide, and isobenzan suppressed the GABA-activated chloride current.
It seems that general anesthetics have a specific affinity for the GABA receptor-channel complex.

The actions of different insecticides known to affect binding of ligands to gamma-aminobutyric acid (GABA) receptors were studied on the function of GABAA receptors in rat brain as assayed by GABA-induced 36Cl- influx into membrane microsacs.
The GABA-induced 36Cl- flux was inhibited by several cyclodienes and gamma-hexachlorocyclohexane (gamma-BHC) with the following order of decreasing potency: endosulfan I greater than endrin greater than endosulfan II greater than dieldrin greater than heptachlor epoxide greater than gamma-BHC greater than heptachlor.
