其他信息

Sigma Aldrich:59-92-7(sigmaaldrich)
系非蛋白氨基酸。L构型，自水中得无色针状结晶。易溶于稀盐酸与甲酸，溶于水，不溶于乙醇、苯、氯仿与乙酸乙酯。在动物体内，多巴经多巴脱羧酶的作用转化为多巴胺。
上游原料:均三甲苯 --> L-酪氨酸 --> 强酸性苯乙烯系阳离子交换树脂 --> 黑色素 --> 多巴

MSDS 信息:Levodopa(59-92-7).msds

用途二:多巴与多巴胺为重要的神经介质。为酪氨酸酶(tyrosinase)、芳香族L-氨基酸脱羧酶（decarboxylase）和乳过氧化物酶(lactoperoxidase)的底物。
用途一:左旋多巴是目前治疗震颤麻痹的有效药物之一，为体内合成去甲肾上腺素、多巴胺等的前体之一，属儿茶酚胺。左旋多巴能通过血脑屏障进入脑中，经多马脱羧酶脱羧转化成多巴胺而发挥作用。但显效较慢，副作用较大。大鼠口服LD50>4000mg/kg。
比旋光度:-11.7 ° (c=5.3, 1N HCl)
方法一:多巴含于一些豆科植物中，在氧化酶作用下能氧化聚合，生成黑素（melanin）。一些豆科植物的荚在成熟时变黑。人及动物的毛、乌贼的墨法、西瓜的种皮等黑色素也属于这类黑素。从藜（Mucuna sempervirens Hemsl）种子中可提取出氨基酸类——左旋多巴。提取方法如下：将藜豆粉碎，用30%乙醇与0.1%乙酸的混合液常温提取3次，每次24h。过滤，得提取液。将提取液减压（21.3kPa）浓缩，析出结晶，在0-10℃静置过夜，过滤，和左旋多巴粗品。粗品用1N盐酸溶解，加活性炭过滤，滤液加少量维生素C用2N氨水中和至pH3.5，析出大量结晶。0-10℃静置4h，过滤。滤饼用含少量维生素C的蒸馏水洗2次，丙酮淋洗脱水1次。60-70℃干燥得左旋多巴。以豆粉计，收率约为2%。左旋多巴也可由L-酪氨酸氧化得到。将酪氨酸溶于甲酸磷酸中，升温至40℃保温12h，用20倍的蒸馏水稀释。稀释液通过强酸性苯乙烯系阳离子交换树脂吸附未反应的酪氨酸，再经后片理操作即得成品。
