制备方法与用途

化学性质

纯白色针状结晶,一般无光泽,可制成明亮且具有弹性的物质。暴露在光中会变暗棕色。无特殊气味,但有持久而强烈的苦味。饱和溶液的石蕊试液呈中性或微碱性。熔点为205℃,加热至100℃时失去结晶。旋光度[α]₂₅℃为-240°~-248°(在200mg溶于0.1mol/L盐酸10ml中测定)。它可溶解于热(比例约为1:35)和乙醇(比例约为1:125),但在氯仿乙醚中的溶解度较低,却能在1:2(体积比)的氯仿-乙醇混合液中大量溶解。

用途

主要用作香料,并常用于配制苦味饮料香精。其化学结构与作用机制类似于奎宁,但效果较弱且不良反应较多,临床中多以氯喹替代使用。目前主要用于治疗耐氯喹疟原虫株感染。

生产方法

奎宁主要是从苯草植物树皮中提取的生物碱。主要品种包括奎宁奎尼丁辛可宁辛可尼丁,其中奎宁的抗疟作用最强。树皮主要分布在印尼、印度等地,我国台湾、海南岛及云南等地区也有产出。生产过程包括将干燥的鸡纳树皮粉碎后用消石和烧碱溶液湿润,再以乙醇浸泡提取。随后调整乙醇提取液pH值至6-6.5并减压浓缩,同时回收乙醇。浓缩液经硫酸烧碱处理及活性炭脱色后结晶得到粗品,再经过精制得到成品。按鸡纳树皮干重计,总收率为2%。

奎宁也可通过化学合成获得,通常是从鸡纳属树(如chinchona succirubra)的树皮提取物硫酸化而成。

    摘要:
    Aiming to deepen the structure-activity relationships of the two P-glycoprotein (P-gp) modulators elacridar and tariquidar, a new series of amide and ester derivatives carrying a 6,7-dimethoxy-2-phenethyl-1,2,3,4-tetrahydroisoquinoline scaffold linked to different methoxy-substituted aryl moieties were synthesised. The obtained compounds were evaluated for their P-gp interaction profile and selectivity towards the two other ABC transporters, multidrug-resistance-associated protein-1 and breast cancer resistance protein, showing to be very active and selective versus P-gp. Two amide derivatives, displaying the best P-gp activity, were tested in co-administration with the antineoplastic drug doxorubicin in different cancer cell lines, showing a significant sensitising activity towards doxorubicin. The investigation on the chemical stability of the derivatives towards spontaneous or enzymatic hydrolysis, showed that amides are stable in both models while some ester compounds were hydrolysed in human plasma. This study allowed us to identify two chemosensitizers that behave as non-transported substrates and are characterised by different selectivity profiles.[GRAPHICS].
