The synthesis of maleimide containing derivatives capable of serving as linkers for the conjugation of proteins is described. These compounds differ from previously reported linkers by having multiple sites available for drug attachment. Compounds 3a, 3b, and 3d were synthesized from the corresponding amino alcohols by the addition of two equivalents of t-butyl bromoacetate to a series of amino alcohols
描述了含有马来酰亚胺的衍生物的合成,该衍生物能够用作蛋白质缀合的连接体。这些化合物与先前报道的接头不同,其具有多个可用于药物附着的位点。通过将两当量的溴乙酸叔丁酯添加到一系列氨基醇中,然后在Mitsunobu反应条件下引入马来酰亚胺并进行酯水解,由相应的氨基醇合成化合物3a,3b和3d。
