loreclezole loreclezole loreclezole is a sedative and an anticonvulsant which acts as a gabaa receptor positive allosteric modulator. the binding site of loreclezole has been shown experimentally to be shared by valerenic acid, an extract of the root of the valerian plant. structurally, loreclezole is a triazole derivative. in animal seizure models, loreclezole is protective against pentylenetetrazol seizures but is less active in the maximal electroshock test. in addition, at low, nontoxic doses, the drug has anti-absence activity in a genetic model of generalized absence epilepsy. consequently, loreclezole has a profile of activity similar to that of benzodiazepines. a potential benzodiazepine-like interaction with gaba receptors is suggested by the observation that the anticonvulsant effects of loreclezole can be reversed by benzodiazepine receptor inverse agonists. the benzodiazepine antagonist flumazenil, however, fails to alter the anticonvulsant activity of loreclezole, indicating that loreclezole is not a benzodiazepine receptor agonist. using native rat and cloned human gaba-a receptors, loreclezole strongly potentiated gaba-activated chloride current. however, activity of the drug did not require the presence of the γ-subunit and was not blocked by flumazenil, confirming that loreclezole does not interact with the benzodiazepine recognition site. loreclezoleclinical dataatc codenoneidentifiers iupac name 1--1h-1,2,4-triazole cas number117857-45-1 ypubchem cid3034012iuphar/bps5466chemspider2298566 yunii6dj32stz5wkeggd04780 ycomptox dashboard (epa)dtxsid6048252 chemical and physical dataformulac10h6cl3n3molar mass274.53 g·mol−1 inchi inchi=1s/c10h6cl3n3/c11-7-1-2-8(9(12)3-7)10(13)4-16-6-14-5-15-16/h1-6h/b10-4- ykey:xglhztbduxxhom-wmzjfqqlsa-n y (verify)
