the presence of the C-21 methyl group in Δ16-alphaxalone, not the location of the constrained C-20 carbonyl group, that prevents Δ16-alphaxalone from interacting strongly with the GABAA receptor and having anesthetic activity. Consistent with this conclusion, a Δ17(20) analogue of Δ16-alphaxalone without a C-21 methyl group was found to be very similar to the anesthetic steroid (3α,5α)-3-hydroxypregnane-11
