  A series of 5-alkylpyrazole derivatives was synthesized and evaluated for potent hypolipidemic activity in rats. Many pyrazole derivatives with an alkyl group at the 5 position of the pyrazole ring were found to possess high hypolipidemic activity. Homologation of the alkyl chain led to marked increase in activity, but introduction of other substituents at other sites on the pyrazole ring failed to

  合成了一系列的5-烷基吡唑衍生物，并对其在大鼠中的有效降血脂活性进行了评估。发现许多在吡唑环的5位具有烷基的吡唑衍生物具有高降血脂活性。烷基链的同源性导致活性显着增加，但是在吡唑环上其他位点引入其他取代基未能增强活性。另外，用异恶唑环取代吡唑环导致活性显着降低。在测试的化合物中，5-n-十三烷基吡唑-3-羧酸（5k）表现出最有利的活性谱，并且与氯贝特一样有效。该化合物5k在急性试验（LD50 = 10.0g / kg）中显示出相当低的毒性，因此目前正在接受进一步的药理评估。

  A protected template molecule and a new one-dimensional UniChemo Protection (UCP) organic synthetic method for preparing polyfunctional organic molecules is described. The synthetic method can be used with many kinds of chemical reactions and provides selective access to many functional groups in a template molecule. The method utilizes protection groups that are each composed of building block units that can be removed one by one affording a new protection group one unit shorter or exposing a functional group on the template molecule. The exposed functional group on the template molecule can react with a target group. Different target groups can be introduced into the template molecule by using protection groups containing different numbers of building block units.

  描述了一种受保护的模板分子和一种新的一维UniChemo Protection（UCP）有机合成方法，用于制备多功能有机分子。这种合成方法可以与许多种化学反应一起使用，并为模板分子中的许多官能团提供选择性访问。该方法利用由建筑单元组成的保护基团，可以逐个移除这些基团，从而获得一个单位较短的新保护基团或者暴露模板分子上的一个官能团。在模板分子上暴露的官能团可以与目标基团发生反应。通过使用包含不同数量建筑单元的保护基团，可以将不同的目标基团引入模板分子中。
