制备方法与用途

简介

6-氨基-5-溴喹喔啉是喹喔啉衍生物的一种重要中间体。其衍生物对原生生物表现出明显的生物活性。类似结构的化合物已被发现是一种选择性α2-肾上腺素能受体兴奋剂。

用途

6-氨基-5-溴喹喔啉作为一种有机中间体,主要用于制备酒石酸溴莫尼定(Brimonidine L-tartrate)。该化合物化学名为5-溴-N-(4,5-二氢-1H-咪唑-2-基)-6-喹喔啉胺-L-酒石酸盐。它是由美国Allergan公司研发的一种新型高度选择性α2-肾上腺素能受体激动剂,于1996年首次在美国上市,商品名为Alphagan。该药物对α2-受体的选择性比可乐定高7~12倍,比阿普拉可乐定高23~32倍。其降眼压效果与可乐定相似,强于阿普拉可乐定,在临床上主要用于治疗开角型青光眼。

制备

将14.52克(0.10摩尔)6-氨基喹喔啉、2.23克(0.01摩尔)CuBr2加入到0.8摩尔/升的氢溴酸水溶液中(总体积150毫升)。然后鼓入氧气维持常压,并将温度控制在90~95℃反应4小时。反应完成后,降至室温,用20%的NaOH溶液调节pH值至9。随后,二氯甲烷(90毫升)进行萃取,纯化水(两次,每次50毫升)洗涤,无水硫酸钠干燥。过滤后,在40℃下真空浓缩并干燥得到6-氨基-5-溴喹喔啉。收率为97.8%,CHPLC纯度为99.94%。

    摘要:
    1.研究了大鼠,兔,狗,猴和人肝脏中14C-溴莫尼定的体外代谢作用,以评估任何物种差异。还研究了兔肝醛氧化酶和人肝切片的体外代谢以及大鼠体内的代谢。通过液相色谱和质谱法表征肝和尿代谢产物。2.在大鼠肝S9级分,人肝S9级分,人肝切片和大鼠尿液中分别检测到多达7、6、11和14种代谢物。兔肝醛氧化酶催化溴莫尼定代谢为2-氧代布罗尼定和3-氧代布罗尼定,并进一步氧化为2,3-二氧代布罗尼定。甲萘醌抑制肝脏醛氧化酶介导的氧化。3.溴莫尼定的肝氧化为2-氧代布罗尼定,3-氧代布罗尼定和2 3-dioxobrimonidine是所有研究物种的主要途径,除了狗的主要代谢产物是4',5'-脱氢溴莫尼定和5-bromo-6-胍基喹喔啉。4.这些结果表明溴莫尼定具有广泛的肝代谢作用,并为醛氧化酶参与溴莫尼定代谢提供了证据。肝溴莫尼定代谢中的物种差异可能与狗肝醛氧化酶的低活性有关。溴莫尼定的主要代谢途径是α(N)-氧化为2

    Transition metal catalysis that utilizes N-heterocyclic carbenes as noninnocent ligands in promoting transformations has not been well studied. We report here a cyclic (alkyl)(amino)carbene (CAAC) ligand-promoted nitro deoxygenative hydroboration with cost-effective chromium catalysis. Using 1 mol % of CAAC-Cr precatalyst, the addition of HBpin to nitro scaffolds leads to deoxygenation, allowing for
