AB  - An updated model of the GABA(A) benzodiazepine receptor pharmacophore of the alpha 5-BzR/GABA(A) subtype has been constructed prompted by the synthesis of subtype selective ligands in light of the recent developments in both ligand synthesis, behavioral studies, and molecular modeling studies of the binding site itself. A number of BzR/GABA(A) alpha 5 subtype selective compounds were synthesized, notably alpha 5-subtype selective inverse agonist PWZ-029 (1) which is active in enhancing cognition in both rodents and primates. In addition, a chiral positive allosteric modulator (PAM), SH-053-2'F-R-CH3 (2), has been shown to reverse the deleterious effects in the MAM-model of schizophrenia as well as alleviate constriction in airway smooth muscle. Presented here is an updated model of the pharmacophore for alpha 5 beta 2 gamma 2 Bz/GABA(A) receptors, including a rendering of PWZ-029 docked within the alpha 5-binding pocket showing specific interactions of the molecule with the receptor. Differences in the included volume as compared to alpha 1 beta 2 gamma 2, alpha 2 beta 2 gamma 2, and alpha 3 beta 2 gamma 2 will be illustrated for clarity. These new models enhance the ability to understand structural characteristics of ligands which act as agonists, antagonists, or inverse agonists at the Bz BS of GABA(A) receptors.

AB  - Inverse agonism at the benzodiazepine site of alpha(5) subunit-containing GABA(A) receptors is an attractive approach for the development of putative cognition-enhancing compounds, which are still far from clinical application. Several ligands with binding and/or functional selectivity for alpha(5) GABA(A) receptors have been synthesized and tested in a few animal models. PWZ-029 is an alpha(5) GABA(A) selective inverse agonist whose memory enhancing effects were demonstrated in the passive avoidance task in rats and in Pavlovian fear conditioning in mice. In the present study we investigated the effects of PWZ-029 administration in novel object recognition test and Morris water maze, in normal and scopolamine-treated rats. All the three doses of PWZ-029 (2,5 and 10 mg/kg) improved object recognition after the 24-h delay period, as shown by significant differences between the exploration times of the novel and old object, and the respective discrimination indices. PWZ-029 (2 mg/kg) also successfully reversed the 0.3 mg/kg scopolamine-induced deficit in recognition memory after the 1-h delay. In the Morris water maze test, PWZ-029 (5,10 and 15 mg/kg) did not significantly influence swim patterns, either during five acquisition days or during the treatment-free probe trial. PWZ-029 (2, 5 and 10 mg/kg) also proved to be ineffective in the reversal of the 1 mg/kg scopolamine-induced memory impairment in the water maze. The present mixed results encourage use of a variety of tests and experimental conditions in order to increase the predictability of preclinical testing of selective as GABA(A) inverse agonists.

AB  - Synthesis of ligands inactive or with low activity at alpha(1) GABA(A) receptors has become the key concept for development of novel, more tolerable benzodiazepine (BZ)-like drugs. WYS8, a remarkably (105 times) alpha(1)-subtype selective partial positive modulator, may serve as a pharmacological tool for refining the role of alpha(1) GABA(A) receptors in mediation of BZs' effects. Here, the effects of WYS8 on GABA-induced currents and on diazepam-induced potentiation of recombinant BZ-sensitive GABA(A) receptors were studied in more detail. In addition, the behavioral profile of WYS8 (0.2, 1, and 10 mg/kg i.p.), on its own and in combination with diazepam, was tested in the spontaneous locomotor activity, elevated plus maze, grip strength, rotarod, and pentylenetetrazole tests. WYS8, applied at an in vivo attainable concentration of 100 nM, reduced the stimulation of GABA currents by 1 mu M diazepam by 57 % at alpha(1)beta(3)gamma(2), but not at alpha(2)beta(3)gamma(2), alpha(3)beta(3)gamma(2), or alpha(5)beta(3)gamma(2) GABA(A) receptors. The administration of WYS8 alone induced negligible behavioral consequences. When combined with diazepam, WYS8 caused a reduction in sedation, muscle relaxation, and anticonvulsant activity, as compared with this BZ alone, whereas ataxia was preserved, and the anxiolytic effect of 2 mg/kg diazepam was unmasked. Hence, a partial instead of full activation at alpha(1) GABA(A) receptors did not necessarily result in the attenuation of the effects assumed to be mediated by activation of these receptors, or in the full preservation of the effects mediated by activation of other GABA(A) receptors. Thus, the role of alpha(1) GABA(A) receptors appears more complex than that proposed by genetic studies.

AB  - Objective : The impairing effects of diazepam in Morris water maze
(MWM) could be partially antagonized with co-administration of an
a5 subunit selective antagonist XLi093 (Savic ́ et al., 2009). In order
to further assess the role of the a5GABAA receptors population
in mediating amnesic effects in rats, the present study examined
effects of an a5GABAA selective agonist XLi356 on the MWM
performance.
Methods : Male Wistar rats were given vehicle or 5, 10 and 20 mg/
kg of XLI356 intraperitoneally 20 minutes before the testing. A single-
day water maze task had three swimming blocks, each consisting of
4 trials, lasting a maximum time of 60 s each. Afterwards, a probe trial
was given and a number of standard parameters was calculated.
Additionally, rats were tested in spontaneous locomotor activity
(SLA) and elevated plus maze (EPM) tests, where the sedative and
anxiolytic effects were assessed.
Results : Results were analyzed using one-way ANOVA with post
hoc Student-Newman-Keuls test where applicable. XLi356 signifi-
cantly increased latency to platform (F(3,444)=3.1287, p=0.026) ; post
hoc test revealed that the dose of 20 mg/kg was significantly different
from vehicle. The same dose of XLi356 significantly increased cumu-
lative distance from the platform zone (p=0.028) and the time spent
in the periphery ring (p=0.009), while the path efficiency was on the
control level. On the other hand, XLi356 did not show behavioral
activity in SLA and EPM tests at either of three doses tested.
Conclusion : The present results suggest that ligands with ap-
preciable agonist activity at GABAA receptors containing a5 subunits
may impair memory acquisition in Morris water maze task, without
discernible effects on general behavior. Thus the activity of the ben-
zodiazepine type drugs at a5GABAA receptors should be decreased if
the amnesic effects are to avoid.

AB  - Objective : It is well known that benzodiazepine binding site ligands
influence learning and memory and that the a5 subunit is significantly
involved in cognition enhancement mediated by the negative modu-
lation of GABAA receptor function. PWZ-029, a moderately selective
a5GABA A receptor inverse agonist, improved learning in passive but
not in active avoidance test, without effects on anxiety or muscle tone.
The aim of this study was to investigate effects of PWZ-029 and
DMCM, a non-selective inverse agonist, on learning ability and short-
term memory in Morris water-maze (MWM) test.
Methods : MWM test was conducted 20 minutes after in-
traperitoneal administration of treatments (solvent, 5, 15 or 30 mg/kg
PWZ-029 or 2 mg/kg DMCM) to male Wistar rats. The single-day
MWM task consisted of 3 consecutive blocks of 4 trials lasting maxi-
mally 60 s each and a probe trial. During spatial learning the platform
was hidden in the middle of the NE quadrant.
Results : Two-way ANOVA with one repeated measure (block) and
animals nested in treatment has shown that latency to find the plat-
form, path efficiency and total distance travelled were on the control
level for DMCM and all doses of PWZ-029. Factors block and treat-
ment were significant only for latency to first entry to the NE quadrant
[block effect : F(2,386)=10.50, p<0.001, treatment effect : F(4,31)=3.10,
p<0.05]. Tukey’s post-hoc test revealed that animals treated with
DMCM and 5 mg/kg of PWZ-029 had longer latency to first entry
to the target quadrant than those treated with solvent (p=0.001,
p<0.001, respectively). Probe trial performance did not differ signifi-
cantly between treatments.
Conclusion : These results suggest that neither non-selective nor b5
subunit-selective negative modulation of GABA A receptors is suf-
ficient to enhance learning and short-term memory in the single-day
MWM spatial task.

abstract = "Objective : It is well known that benzodiazepine binding site ligands
influence learning and memory and that the a5 subunit is significantly
involved in cognition enhancement mediated by the negative modu-
lation of GABAA receptor function. PWZ-029, a moderately selective
a5GABA A receptor inverse agonist, improved learning in passive but
not in active avoidance test, without effects on anxiety or muscle tone.
The aim of this study was to investigate effects of PWZ-029 and
DMCM, a non-selective inverse agonist, on learning ability and short-
term memory in Morris water-maze (MWM) test.
Methods : MWM test was conducted 20 minutes after in-
traperitoneal administration of treatments (solvent, 5, 15 or 30 mg/kg
PWZ-029 or 2 mg/kg DMCM) to male Wistar rats. The single-day
MWM task consisted of 3 consecutive blocks of 4 trials lasting maxi-
mally 60 s each and a probe trial. During spatial learning the platform
was hidden in the middle of the NE quadrant.
Results : Two-way ANOVA with one repeated measure (block) and
animals nested in treatment has shown that latency to find the plat-
form, path efficiency and total distance travelled were on the control
level for DMCM and all doses of PWZ-029. Factors block and treat-
ment were significant only for latency to first entry to the NE quadrant
[block effect : F(2,386)=10.50, p<0.001, treatment effect : F(4,31)=3.10,

AB  - Benzodiazepines negatively affect motor coordination and balance and produce myorelaxation. The aim of the present study was to examine the extent to which populations of gamma-aminobutyric acid A (GABA(A)) receptors containing alpha(1) and alpha(5) subunits contribute to these motor-impairing effects in rats. We used the nonselective agonist diazepam and the alpha(1)-selective agonist zolpidem, as well as nonselective, alpha(1)-subunit and alpha(5)-subunit-selective antagonists flumazenil, beta CCt, and XLi093, respectively. Ataxia and muscle relaxation were assessed by rotarod and grip strength tests performed 20 min after intraperitoneal treatment. Diazepam (2 mg/kg) induced significant ataxia and muscle relaxation, which were completely prevented by pretreatment with flumazenil (10mg/kg) and beta CCt (20 mg/kg). XLi093 antagonized the myorelaxant, but not the ataxic actions of diazepam. All three doses of zolpidem (1, 2, and 5 mg/kg) produced ataxia, but only the highest dose (5 mg/kg) significantly decreased the grip strength. These effects of zolpidem were reversed by beta CCt at doses of 5 and 10 mg/kg, respectively. The present study demonstrates that alpha(1) GABA(A) receptors mediate ataxia and indirectly contribute to myorelaxation in rats, whereas alpha(5) GABA(A) receptors contribute significantly, although not dominantly, to muscle relaxation but not ataxia.

AB  - The clinical use of benzodiazepines (BZs) is hampered by sedation and cognitive deterioration. Although genetic and pharmacological studies suggest that alpha(1)- and alpha(5)-containing GABA(A) receptors mediate and/or modulate these effects, their molecular substrate is not fully elucidated. By the use of two selective ligands: the alpha(1)-subunit affinity-selective antagonist beta-CCt, and the alpha(5)-subunit affinity- and efficacy-selective antagonist XLi093, we examined the mechanisms of behavioural effects of diazepam in the tests of spontaneous locomotor activity and water-maze acquisition and recall, the two paradigms indicative of sedative- and cognition-impairing effects of BZs, respectively. The locomotor-activity decreasing propensity of diazepam (significant at 1.5 and 5 mg/kg) was antagonized by beta-CCt (5 and 15 mg/kg), while it tended to be potentiated by XLi093 in doses of 10 mg/kg, and especially 20 mg/kg. Diazepam decreased acquisition and recall in the water maze, with a minimum effective dose of 1.5 mg/kg. Both antagonists reversed the thigmotaxis induced by 2 mg/kg diazepam throughout the test, suggesting that both GABA(A) receptor subtypes participate in BZ effects on the procedural component of the task. Diazepam-induced impairment in the declarative component of the task, as assessed by path efficiency, the latency and distance before finding the platform across acquisition trials, and also by the spatial parameters in the probe trial, was partially prevented by both, 15 mg/kg beta-CCt and 10 mg/kg XLi093. Combining a BZ with beta-CCt results in the near to control level of performance of a cognitive task, without sedation, and may be worth testing on human subjects.
