用途 编辑

烏頭鹼以前被用作解熱藥和鎮痛藥,但在草藥中的應用仍然有限。狹窄的治療指數使計算合適的劑量很困難。[4]

結構和反應性 编辑

附子屬翠雀屬植物的生物活性分離物被歸類為去甲二萜生物碱。[5]根據C18碳的存在與否進一步細分。[6]烏頭鹼是一種C19去甲二萜生物碱,因為它含有C18。烏頭鹼幾乎不溶於,但極易溶於有機溶劑,例如氯仿或乙醚。[7][8]如果酒精濃度足夠高,烏頭鹼也可溶於乙醇和水的混合物中。

像許多其他生物鹼一樣,烏頭鹼六元環的鹼性很容易形成鹽和離子,使其對極性親脂性結構過血腦屏障[9]

毒性 编辑

烏頭鹼的毒性作用已在多種動物身上進行了測試有效,包括哺乳動物(狗、貓、豚鼠、小鼠、大鼠和兔子)、鴿、青蛙。觀察到的毒性作用有:局部麻醉腹瀉抽搐心律失常、死亡。[37][38]

根據對人類附子中毒的不同報導的回顧,觀察到以下臨床特徵:[4]

  • 神經系統:感覺異常和臉、口周區域和四肢麻木、肌肉無力。
  • 心血管:低血壓心悸、胸痛、心動過緩、竇性心動過速、室性異位及其他心律失常、室性心律失常、交界性心律
  • 胃腸道:噁心、嘔吐、腹痛、腹瀉
  • 其他:頭暈、過度換氣、出汗、呼吸困難、意識模糊、頭痛、流淚

烏頭鹼中毒的最初症狀出現在口服後約20分鐘至2小時,包括感覺異常、出汗、噁心。這會導致嚴重的嘔吐、絞痛性腹瀉、劇烈疼痛,然後骨骼肌麻痺。威脅生命的心律失常,包括室性心動過速、心室顫動,會因呼吸麻痺或心臟驟停而死亡。[25]

小鼠的LD50值為口服 1 mg/kg、靜脈 0.100 mg/kg、腹膜 0.270 mg/kg 和皮下 0.270 mg/kg。小鼠的最低致死量LDLo)為口服 1 mg/kg 和腹腔 0.100 mg/kg。小鼠的最低中毒量(TDLo)為 0.0549 mg/kg 皮下注射。大鼠靜脈注射的LD50值為 0.064 mg/kg。大鼠的LDLo為靜脈注射 0.040 mg/kg和腹腔 0.250 mg/kg。大鼠的腸胃TDLo為 0.040 mg/kg。有關更多參見下表:LD50表示平均致死量;LDLo是指最低致死量;TDLo表示最低中毒量。[38]

dependent sodium ion channels which are proteins in the cell membranes of excitable tissues such as cardiac and skeletal muscles and neurons These proteins are highly selective for sodium ions They open very quickly to depolarize the cell membrane potential causing the upstroke of an action potential Normally the sodium channels close very rapidly but the depolarization of the membrane potential causes the opening activation of potassium channels and potassium efflux which results in repolarization of the membrane potential Aconitine binds to the channel at the neurotoxin binding site 2 on the alpha subunit 13 This binding results in a sodium ion channel that stays open longer Aconitine suppresses the conformational change in the sodium ion channel from the active state to the inactive state The membrane stays depolarized due to the constant sodium influx which is 10 1000 fold greater than the potassium efflux As a result the membrane cannot be repolarized The binding of aconitine to the channel also leads to the channel to change conformation from the inactive state to the active state at a more negative voltage 14 In neurons aconitine increases the permeability of the membrane for sodium ions resulting in a huge sodium influx in the axon terminal As a result the membrane depolarizes rapidly Due to the strong depolarization the permeability of the membrane for potassium ions increases rapidly resulting in a potassium reflux to release the positive charge out of the cell Not only the permeability for potassium ions but also the permeability for calcium ions increases as a result of the depolarization of the membrane A calcium influx takes place The increase of the calcium concentration in the cell stimulates the release of the neurotransmitter acetylcholine into the synaptic cleft Acetylcholine binds to acetylcholine receptors at the postsynaptic membrane to open the sodium channels there generating a new action potential Research with mouse nerve hemidiaphragm muscle preparation indicate that at low concentrations lt 0 1 mM aconitine increases the electrically evoked acetylcholine release causing an induced muscle tension 15 Action potentials are generated more often at this concentration At higher concentration 0 3 3 mM aconitine decreases the electrically evoked acetylcholine release resulting in a decrease in muscle tension At high concentration 0 3 3 mM the sodium ion channels are constantly activated transmission of action potentials is suppressed leading to non excitable target cells or paralysis 合成 编辑 已隱藏部分未翻譯内容 歡迎參與翻譯 Aconitine is biosynthesized by the monkshood plant via the terpenoid biosynthesis pathway MEP chloroplast pathway 16 Approximately 700 naturally occurring C19 diterpenoid alkaloids have been isolated and identified but the biosynthesis of only a few of these alkaloids are well understood 17 Likewise only a few alkaloids of the aconitine family have been synthesized in the laboratory In particular despite over one hundred years having elapsed since its isolation the prototypical member of its family of norditerpenoid alkaloids aconitine itself represents a rare example of a well known natural product that has yet to succumb to efforts towards its total synthesis The challenge that aconitine poses to synthetic organic chemists is due to both the intricate interlocking hexacyclic ring system that make up its core and the elaborate collection of oxygenated functional groups at its periphery A handful of simpler members of the aconitine alkaloids however have been prepared synthetically In 1971 the Weisner group discovered the total synthesis of talatisamine a C19 norditerpenoid 18 In the subsequent years they also discovered the total syntheses of other C19 norditerpenoids such as chasmanine 19 and 13 deoxydelphonine 20 nbsp Schematic for the syntheses of Napelline Deoxydelphonine and Talatisamine Wiesner Syntheses of Napelline Deoxydelphonine and TalatisamineThe total synthesis of napelline Scheme a begins with aldehyde 100 18 In a 7 step process the A ring of napelline is formed 104 It takes another 10 steps to form the lactone ring in the pentacyclic structure of napelline 106 An additional 9 steps creates the enone aldehyde 107 Heating in methanol with potassium hydroxide causes an aldol condensation to close the sixth and final ring in napelline 14 Oxidation then gives rise to diketone 108 which was converted to napelline 14 in 10 steps A similar process is demonstrated in Wiesner s synthesis of 13 desoxydelphinone Scheme c 19 The first step of this synthesis is the generation of a conjugated dienone 112 from 111 in 4 steps This is followed by the addition of a benzyl vinyl ether to produce 113 In 11 steps this compound is converted to ketal 114 The addition of heat DMSO and o xylene rearranges this ketol 115 and after 5 more steps 13 desoxydelphinone 15 is formed Lastly talatisamine Scheme d is synthesized from diene 116 and nitrile 117 20 The first step is to form tricycle 118 in 16 steps After another 6 steps this compound is converted to enone 120 Subsequently this allene is added to produce photoadduct 121 This adduct group is cleaved and rearrangement gives rise to the compound 122 In 7 steps this compound forms 123 which is then rearranged in a similar manner to compound 114 to form the aconitine like skeleton in 124 A racemic relay synthesis is completed to produce talatisamine 13 More recently the laboratory of the late David Y Gin completed the total syntheses of the aconitine alkaloids nominine 21 and neofinaconitine 22 代謝 编辑 已隱藏部分未翻譯内容 歡迎參與翻譯 nbsp Aconine an amorphous bitter non poisonous alkaloid derived from the decomposition of aconitineAconitine is metabolized by cytochrome P450 isozymes CYPs There has been research in 2011 in China to investigate in depth the CYPs involved in aconitine metabolism in human liver microsomes 23 It has been estimated that more than 90 percent of currently available human drug metabolism can be attributed to eight main enzymes CYP 1A2 2C9 2C8 2C19 2D6 2E1 3A4 3A5 24 The researchers used recombinants of these eight different CYPs and incubated it with aconitine To initiate the metabolism pathway the presence of NADPH was needed Six CYP mediated metabolites M1 M6 were found by liquid chromatography these six metabolites were characterized by mass spectrometry The six metabolites and the involved enzymes are summarized in the following table Metabolite Name Involved CYPsM1 O Demethyl aconitine CYP3A4 CYP3A5 CYP2D6 CYP2C8M2 16 O Demethyl aconitine CYP3A4 CYP3A5 CYP2D6 CYP2C9M3 N deethyl aconitine CYP3A4 CYP3A5 CYP2D6 CYP2C9M4 O didemethyl aconitine CYP3A5 CYP2D6M5 3 Dehydrogen aconitine CYP3A4 CYP3A5M6 Hydroxyl aconitine CYP3A5 CYP2D6Selective inhibitors were used to determine the involved CYPs in the aconitine metabolism The results indicate that aconitine was mainly metabolized by CYP3A4 3A5 and 2D6 CYP2C8 and 2C9 had a minor role to the aconitine metabolism whereas CYP1A2 2E1 and 2C19 did not produce any aconitine metabolites at all The proposed metabolic pathways of aconitine in human liver microsomes and the CYPs involved to it are summarized in the table above 診斷和治療 编辑 已隱藏部分未翻譯内容 歡迎參與翻譯 For the analysis of the Aconitum alkaloids in biological specimens such as blood serum and urine several GC MS methods have been described These employ a variety of extraction procedures followed by derivatisation to their trimethylsilyl derivatives New sensitive HPLC MS methods have been developed as well usually preceded by SPE purification of the sample 25 The antiarrhythmic drug lidocaine has been reported to be an effective treatment of aconitine poisoning of a patient Considering the fact that aconitine acts as an agonist of the sodium channel receptor antiarrhythmic agents which block the sodium channel Vaughan Williams classification I might be the first choice for the therapy of aconitine induced arrhythmias 26 Animal experiments have shown that the mortality of aconitine is lowered by tetrodotoxin The toxic effects of aconitine were attenuated by tetrodotoxin probably due to their mutual antagonistic effect on excitable membranes 27 Also paeoniflorin seems to have a detoxifying effect on the acute toxicity of aconitine in test animals This may result from alternations of pharmacokinetic behavior of aconitine in the animals due to the pharmacokinetic interaction between aconitine and paeoniflorin 28 In addition in emergencies one can wash the stomach using either tannic acid or powdered charcoal Heart stimulants such as strong coffee or caffeine may also help until professional help is available 29 著名中毒事件 编辑 已隱藏部分未翻譯内容 歡迎參與翻譯 During the Indian Rebellion of 1857 a British detachment was the target of attempted poisoning with aconitine by the Indian regimental cooks The plot was thwarted by John Nicholson who having detected the plot interrupted the British officers just as they were about to consume the poisoned meal The chefs refused to taste their own preparation whereupon it was force fed to a monkey who expired on the spot The cooks were hanged Aconitine was the poison used by George Henry Lamson in 1881 to murder his brother in law in order to secure an inheritance Lamson had learned about aconitine as a medical student from professor Robert Christison who had taught that it was undetectable but forensic science had improved since Lamson s student days 30 31 32 Rufus T Bush American industrialist and yachtsman died on September 15 1890 after accidentally taking a fatal dose of aconite In 1953 aconitine was used by a Soviet biochemist and poison developer Grigory Mairanovsky in experiments with prisoners in the secret NKVD laboratory in Moscow He admitted killing around 10 people using the poison 33 In 2004 Canadian actor Andre Noble died from aconitine poisoning He accidentally ate some monkshood while he was on a hike with his aunt in Newfoundland In 2009 Lakhvir Singh of Feltham west London used aconitine to poison the food of her ex lover Lakhvinder Cheema who died as a result of the poisoning and his current fiancee Aunkar Singh Singh received a life sentence with a 23 year minimum for the murder on February 10 2010 34 流行文化 编辑 已隱藏部分未翻譯内容 歡迎參與翻譯 烏頭鹼是古代世界最受歡迎的毒藥 普布利烏斯 奧維修斯 納索提到了眾所周知的繼母不喜歡繼子的問題 他寫道 Lurida terribiles miscent
