tp-13 tp-13 tp-13 is an anxiolytic drug with a novel chemical structure, which is used in scientific research. it has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic. it is a subtype-selective partial agonist at gabaa receptors, binding selectively to gabaa receptor complexes bearing α2 and α3 subunits. it has modest anticonvulsant activity although less than that of diazepam, and its main effect is likely to be selective anxiolytic action, as seen with other related α2/3-preferring agonists such as l-838,417. tp-13identifiers iupac name 7-cyclobutyl-6-(2-ethyl-2h-1,2,4-triazol-3-ylmethoxy)-3-phenyl-1,2,4-triazolo pyridazine cas number202930-12-9pubchem cid9799023chemspider7974788uniidkp4ygh6wnchemical and physical dataformulac19h19n7omolar mass361.409 g·mol−13d model (jsmol)interactive image smiles c5ccc5c3cc2nnc(-c4ccccc4)n2nc3occ1ncnn1c inchi inchi=1s/c19h19n7o/c1-25-17(20-12-21-25)11-27-19-15(13-8-5-9-13)10-16-22-23-18(26(16)24-19)14-6-3-2-4-7-14/h2-4,6-7,10,12-13h,5,8-9,11h2,1h3key:vacjukkurqmwhe-uhfffaoysa-n (verify)
