Esters and amino acid derivatives of 5-aminolevulinic acid (ALA) are efficient prodrugs for the production of protoporphyrin IX (PpIX), which has been used in photodynamic cancer therapy (PDT). The synthesis of novel bioconjugates combining ALA with adenosine and thymidine is reported. The novel bioconjugates have been made using a robust methodology. The new class of prodrugs contains one, two, or three ALA per molecule. Preliminary cell tests in human cancer cell lines indicate that the thymidine conjugate of ALA is an efficient prodrug for PDT.
5- 氨基乙酰丙酸(ALA)的酯类和氨基酸衍生物是生产原卟啉 IX(PpIX)的有效原药,PpIX 已被用于光动力癌症疗法(PDT)。本研究报道了 ALA 与腺苷和胸苷结合的新型生物共轭物的合成。这种新型生物缀合物是采用一种稳健的方法制成的。新型原药的每个分子含有一个、两个或三个 ALA。在人类癌细胞系中进行的初步细胞测试表明,ALA 的胸腺嘧啶共轭物是一种有效的光动力疗法原药。
