新煙草鹼

化合物

新煙草鹼(英語:Anatabine)又稱去氫毒藜鹼,是一種存在於茄科植物中的微量生物鹼。商用煙草中一般含有2-4%(乾重)的生物鹼[1],其中尼古丁佔據其中90%,剩餘10%則包括新煙草鹼、降煙鹼假木賊鹼(新煙鹼)等微量生物鹼,這類生物鹼是茄科植物用於防禦害蟲而產生[2]

新煙草鹼在體內外可抑制STAT3蛋白磷酸化,並產生抗炎活性[3]。同時似乎對煙鹼型乙酰膽鹼受體有活性作用[4]

商業化

美國Star Scientific煙草公司在2014年中之前開發了兩款含有新煙草鹼的膳食補充劑,並以CigRx和Anatabloc的商品名進行銷售。隨後旗下子公司Rock Creek製藥(Rock Creek Pharmaceuticals)開始將新煙草鹼開發為藥物[5][6][7],並研究擴大新煙草鹼產量的方法,此外還額外資助了其幾種適應症的臨床前和臨床研究[5]

直到2013年,FDA警告在證明兩款膳食補充劑是安全的之前,Star Scientific涉嫌非法推廣[8][9]。受此影響,Rock Creek公司高層發生人員大幅度變更,新高層以及幾乎全新的董事會撤回了這兩款產品。同年Star Scientific公司陷入政治醜聞,有消息稱維珍尼亞州州長鮑勃·麥克唐納和其妻子被指控從Star Scientific行政總裁喬尼·威廉姆斯(Jonnie Williams)收受大額賄賂,並反過來推介公司產品作為報答,包括如安排與高層官員會面,以及給予州政府特殊恩惠等[6]。受此事件影響,威廉姆斯於2014年辭去CEO職務,Star Scientific公司於2013年底進行董事會和管理層重組並更名[5]

然而,威廉姆斯在此事件中辯護所產生的總法律費用超出了公司的財務承受能力,導致公司於2016年申請破產,新煙草鹼的研發和臨床試驗被無限期暫停[10]

醫學研究

人們已經在動物模型和細胞中研究新煙草鹼是否可能有助於治療尼古丁成癮和炎症。並且已對包括阿茲海默症[11]甲狀腺炎[12]多發性硬化症[4] 在內的炎症特徵疾病模型中進行了研究。此外,新煙草鹼發現有助於治療輕中度酒渣鼻[13]。一項基於互聯網的調查顯示,82% 的用戶報告稱補充新煙草鹼對一種或多種關節疼痛有一定改善作用[14]
