A selective α7 nAChR-positive allosteric modulator (PAM) from a library of GABAA receptor PAMs is generated, which corrects sensory-gating deficits and improves working memory, effects consistent with cognitive enhancement in rodent models.
Characterization of the anticonvulsant properties of Ganaxolone (CCD 1042; 3α-hydroxy-3β-methyl-5α-pregnan-20-one), a selective, high-affinity, steroid modulator of the γ-aminobutyric acid(A) receptor
Data indicate that ganaxolone is a high-affinity, stereoselective, positive allosteric modulator of the GABAA receptor complex that exhibits potent anticonvulsant activity across a range of animal procedures.

The conformationally restricted, cyclic, disulfide-containing, enkephalin analogs and the bis-Pen-containing analogs provide an order of magnitude increase in delta receptor selectivity.

In vitro studies of steroids active at the gamma-aminobutyric acidA (GABAA) receptor regulated Cl- channel labeled by [35S]-t-butylbicyclophosphorothionate reveal additional structural requirements necessary for activity, providing additional support for the hypothesis that some of these steroids may be involved in the homeostatic regulation of brain excitability via the GABAA-BZ receptor complex.
Anticonvulsant steroids and the GABA/benzodiazepine receptor-chloride ionophore complex
Anxiolytic activity of the progesterone metabolite 5α-pregnan-3α-ol-20-one
CCD-3693: an orally bioavailable analog of the endogenous neuroactive steroid, pregnanolone, demonstrates potent sedative hypnotic actions in the rat.
In vitro binding studies and in vivo pharmacological data confirmed that CCD-3693 was orally active in standard tests of anxiety, anticonvulsant, loss-of-righting and passive avoidance, and appeared more intrinsically efficacious in promoting NREM sleep than the benzodiazepine ligands.

The estrus cycle, sensitivity to convulsants and the anticonvulsant effect of a neuroactive steroid.
In vivo studies evaluated estrus cycle-related differences in sensitivity to convulsants and the anticonvulsant effect of 3 alpha, 5 alpha-P to find that females in estrus were more sensitive than females in diestrus 1 or males to (+)-bicuculline and methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3- carboxylate.
A putative receptor for neurosteroids on the GABAA receptor complex: the pharmacological properties and therapeutic potential of epalons.
Based upon some of the unique characteristics of the epalons relative to barbiturates and the BZs, it is plausible that the epAlons can be developed into a novel class of therapeutic agents for the treatment of anxiety, epilepsy, and insomnia.
