Tracazolate reveals a novel type of allosteric interaction with recombinant gamma-aminobutyric acid(A) receptors.[Pubmed:11901225]

Mol Pharmacol. 2002 Apr;61(4):861-9.

Tracazolate, a pyrazolopyridine, is an anxiolytic known to interact with gamma-aminobutyric acid (GABA)(A) receptors, adenosine receptors, and phosphodiesterases. Its anxiolytic effect is thought to be via its interaction with GABA(A) receptors. We now report the first detailed pharmacological study examining the effects of tracazolate on a range of recombinant GABA(A) receptors expressed in Xenopus laevis oocytes. Replacement of the gamma2s subunit within the alpha1beta3gamma2s receptor with the epsilon subunit caused a dramatic change in the functional response to tracazolate from potentiation to inhibition. The gamma2s subunit was not critical for potentiation because alpha1beta3 receptors were also potentiated by tracazolate. gamma2/epsilon chimeras revealed a critical N-terminal domain between amino acids 206 and 230 of gamma2, governing the nature of this response. Replacement of the beta3 subunit with the beta1 subunit within alpha1beta3gamma2s and alpha1beta3epsilon receptors also revealed selectivity of tracazolate for beta3-containing receptors, determined by asparagine at position 265 within transmembrane 2. Replacement of gamma2s with gamma1 or gamma3 revealed a profile intermediate to that of alpha1beta1epsilon and alpha1beta1gamma2s. alpha1beta1delta receptors were also potentiated by tracazolate; however, the maximum potentiation of the EC(20) was much greater than on alpha1beta1gamma2. Concentration-response curves to GABA in the presence of tracazolate for alpha1beta1epsilon and alpha1beta1gamma2s revealed a concentration-related decrease in maximum current amplitude, but a leftward shift in the EC(50) only on alpha1beta1gamma2. Like alpha1beta1gamma2s, GABA concentration-response curves on alpha1beta1delta receptors were shifted to the left with increased maximum responses. Tracazolate has a unique pharmacological profile on recombinant GABA(A) receptors: its potency (EC(50)) is influenced by the nature of the beta subunit; but more importantly, its intrinsic efficacy, potentiation, or inhibition is determined by the nature of the third subunit (gamma1-3, delta, or epsilon) within the receptor complex.

Enhancement of benzodiazepine and GABA binding by the novel anxiolytic, tracazolate.[Pubmed:6121710]

Eur J Pharmacol. 1982 Mar 12;78(3):315-22.

Tracazolate (ICI 136,753) 4-butylamine-1-ethyl-6-methyl-1H-pyrazolo[3,4]pyridine-5-carboxylic acid ethyl ester is a non-benzodiazepine with anxiolytic-like activity in animal models. In contrast to the benzodiazepines, it enhances [3H]flunitrazepam binding in rat synaptic membrane fragments. The enhancement is potential by chloride ion and is due to an increase in affinity of the receptor. The enhancement of benzodiazepine binding by gamma-aminobutyric acid (GABA) is additive with that of tracazolate; however, the GABA antagonist bicuculline blocks the enhancement by both compounds. Tracazolate enhances [3H]GABA binding to frozen and thawed Triton X-100-treated membrane fragments. The enhancement is due to an increase in the number of sites and potentiated by chloride. Benzodiazepines also enhanced GABA binding but the effect was due to an apparent change in affinity and not potentiated by chloride. The rank order to chlorodiazepoxide, diazepam and flunitrazepam for enhancement of GABA binding and displacement of [3H]flunitrazepam binding were the same. The enhancement of [3H]GABA binding by flunitrazepam and tracazolate were additive. Possible interactions between these various receptors are discussed.

Pharmacological properties of tracazolate: a new non-benzodiazepine anxiolytic agent.[Pubmed:6121711]

Eur J Pharmacol. 1982 Mar 12;78(3):323-33.

Tracazolate (ICI 136,753, 4-butylamino-1-ethyl-6-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylic acid ethyl ester) demonstrated dose-related anticonflict activity in rats and mice. The potency of tracazolate appears to be one-quarter to one-half that of chlordiazepoxide. No tolerance to the anticonflict activity of either tracazolate or chlordiazepoxide was evident following 12 consecutive days of treatment. Tracazolate exhibits a much greater separation between sedative and therapeutic doses than does chlordiazepoxide. Furthermore, based on rodent studies, tracazolate should be much less likely than the benzodiazepines to potentiate the actions of barbiturates and ethanol in man. Tracazolate potentiated both the anticonvulsant and anxiolytic effects of chlordiazepoxide in rodents. Unlike benzodiazepines, tracazolate enhances the binding of benzodiazepines to its receptor site. These results suggest that tracazolate is a novel agent with potential clinical utility as an anxiolytic drug.
