  Improved Peptide Prodrugs of 5-ALA for PDT: Rationalization of Cellular Accumulation and Protoporphyrin IX Production by Direct Determination of Cellular Prodrug Uptake and Prodrug Metabolization

  摘要：

  Twenty-seven dipeptide derivatives of general structure Ac-Xaa-ALA-OR were synthesized as potential prodrugs for 5-aminolaevulinic acid-based photodynamic therapy (ALA-PDT). Xaa is an (x-amino acid, chosen to provide a prodrug with appropriately tailored lipophilicity and water solubility. Although no simple correlation is observed between downstream production of protoporphyrin IX (PpIX) in PAM212 keratinocytes and HPLC-derived descriptors of compound lipophilicity, quantification of prodrug uptake reveals that most of the dipeptides are actually more efficiently accumulated than ALA in PAM212 and also A549 and Caco-2 cell lines. Subsequent ALA release is the limiting factor, which emphasizes the importance of decoupling prodrug uptake and intracellular metabolization when assessing the efficacy of ALA derivatives for PDT. In agreement with PpIX fluorescence studies, at,I concentration of 0.1 MM, L-Phe derivatives 4m and 4o, and L-Leu, L-Met, and L-Glu derivatives 4f, 4k, and 4u, exhibit significantly enhanced photoxicity in PAM212 cells compared to ALA.

To evaluate means to specifically target ALA derivatives to defined cells, we have synthesized and characterized ethylene glycol esters and amino acid pseudodipeptide derivatives of ALA as potential specific substrates for cellular esterases and aminopeptidases, respectively. The PpIX formation induced by these

  原卟啉IX（PpIX）在癌症的光动力检测和治疗（PDT）中用作光敏剂，由氨基乙酰丙酸（ALA）前体在细胞内合成。为了评估将ALA衍生物特异性靶向特定细胞的方法，我们合成并表征了ALA的乙二醇酯和氨基酸假二肽衍生物分别作为细胞酯酶和氨基肽酶的潜在特异性底物。使用人类和大鼠的癌细胞系和内皮细胞培养物研究了由这些产物诱导的PpIX形成。这些化合物在没有光照的情况下的细胞毒性也得到了控制。结果表明，乙二醇酯可以诱导高水平的PpIX，并在低于其细胞毒性阈值的浓度下有用。
