制备方法与用途

用途:利尿酸的中间体。

生产方法:在碱性条件下,使用2,3-二氯苯酚和硫酸二甲酯进行甲基化(羟基保护),生成2,3-二氯苯甲醚。随后,在无水三氯化铝的作用下与丁酰氯缩合,并通过水解脱除甲基,最终制得目标产物。

    摘要:
    摘要 合成了乙烯酰基酸及其一系列类化合物,并随后评估了它们对豌豆尿素酶的抑制作用。乙烯酰基酸即使在低浓度下也显示出对该酶非常强的抑制活性。对于乙烯酰基酸,抑制潜力随着乙烯酰基酸和酶的预孵育时间的增加而增强,然而对于其他一些化合物,较长的预孵育时间会显著降低其活性。我们证明了我们化合物中的α,β-不饱和羰基单元对抑制该酶是必不可少的,可能是由于它能够与豌豆尿素酶活性位点中的半胱氨酸残基结合。

    A series of etacrynic acid derivatives was synthesized and screened for their in vitro activity against Plasmodium falciparum, as well as their activity against recombinantly expressed falcipain-2 and -3. The two most active compounds of the series displayed IC50 values of 9.0 and 18.8 μM against Plasmodia.

    In search of a drug to treat sickle cell anemia, several analogues of the diuretic ethacrynic acid (ECA) have been synthesized and found equivalent in antigelling potency to ECA, but they have moderate or little diuretic activity. Structure-activity studies revealed that most of the highly active derivatives contain an acryloyl moiety. The latter functionality reacts covalently with protein sulfhydryl
    为了寻找治疗镰状细胞性贫血的药物,已经合成了几种利尿剂乙炔酸(ECA)的类似物,并发现其抗胶凝作用与ECA相当,但是它们具有中等或几乎没有利尿作用。结构活性研究表明,大多数高活性衍生物都含有丙烯酰基部分。后者的功能性通过迈克尔加成反应与蛋白质巯基共价反应。缺少丙烯酰基部分的其他衍生物显示出明显较低的抗胶凝活性。由于抗凝胶化试验是在厌氧条件下进行的,因此活性暗示了脱氧血红蛋白S聚合的立体化学抑制作用。从[HbS药物] / [HbS对照]几种化合物(表I)获得的溶解度比值接近具有临床潜力(1.06-1。
