Barbituric Acid (CAS: 67-52-7), Barbiturates yog derivatives ntawm barbituric acid, barbituric acid yog tsim los ntawm condensation ntawm malonic acid thiab urea, nws tus kheej tsis muaj tshuaj loog, tab sis yog hais tias nws C2 thiab C5 atoms yog hloov los ntawm txawv noob. , nws tuaj yeem tsim ntau hom kab mob barbiturate, piv txwv li, oxygen ntawm C2 yog hloov los ntawm leej faj, uas tsim cov sulfur barbiturates, xws li thiopental.Barbiturates 'txheej txheem yog qhov zoo ib yam, lawv ua rau ntau theem ntawm lub hauv paus paj hlwb, thiab muaj kev txwv tsis pub tshwj xeeb.Nws cov teebmeem sedative thiab hypnotic tej zaum yuav muaj feem xyuam rau kev xaiv inhibition ntawm thalamic reticular upstream activating system, yog li thaiv cov excite transduction mus rau cerebral cortex.Nws cov nyhuv Anticonvulsant yog ua los ntawm inhibiting synaptic kis tau tus mob nyob rau hauv lub hauv paus paj hlwb, los txhim kho cov hluav taws xob stimulation pib nyob rau hauv lub cev muaj zog cortex.Barbiturates muaj cov nyhuv kho mob ua lub luag haujlwm inhibiting hauv nruab nrab paj hlwb, xws li phenobarbital (phenobarbitone), amobarbital (amylobarbitone), thiopental, methohexital (methohexi-tone).Inhibitory barbiturates muaj sedative, hypnotic, anticonvulsant thiab tshuaj loog los, tab sis nws cov sedative-hypnotic tus neeg sawv cev tau raug tshem tawm, vim hais tias nyob rau hauv tus txheej txheem nws yog ib qho yooj yim mus tsim ib tug mob siab heev, tshuaj dependence thiab tshuaj siab enzyme induction.
