摘要
癌症是现代世界的主要社会问题之一。今天,前列腺癌是男性癌症死亡的第二大原因。靶向药物递送广泛用于治疗和诊断前列腺癌。基于尿素配体的选择性结合前列腺特异性膜抗原的偶联物正在积极开发,以对抗这种疾病。连接子对这种偶联物的生物活性有显著影响。连接子执行大量功能,其修饰是创建最佳药理学特征的关键方法之一。本文旨在探讨和分析该类偶联物导联物引入和合成方法的主要方法,而不描述生物活性分子的影响,并建立对构效关系具有重要作用的关键修饰方法。为此,对当前的科学文献进行了回顾,包括正在开发的偶联物和已经进行临床试验的偶联物。发现最佳结构是含有载体分子(n(CH2)= 3-6)附近的脂肪族片段的连接子,然后是由2至4个氨基酸残基组成的多肽链。Phe-Phe二肽链的存在或带负电荷的基团的引入也具有积极作用。该领域正在进行的研究有助于建立每个连接子片段的准确效果,并且固相合成方法的发展使得实现这一目标变得更加容易。
关键词: 前列腺癌,靶向药物递送,接头,PSMA,接头结构,偶联物合成,间隔物。
