5‐Aminolevulinic Acid Derivatives in Photomedicine: Characteristics, Application and Perspectives

Abstract: The introduction of lipophilic derivatives of the naturally occurring heme precursor 5-aminolevulinic acid (5-ALA) into photomedicine has led to a true revival of this research area. 5-ALA-mediated photodynamic therapy (PDT) and fluorescence photodetection (FD) of neoplastic disease is probably one of the most selective cancer treatments currently known in oncology. To date, this method has been assessed experimentally for the treatment of various medical indications. However, the limited local bioavailability… Show more

“…[16][17][18][19] Albeit improved in the terms of lipophilicity, ALA-Hex remains toxic with a poor systemic pharmacokinetic profile thus still not providing an optimal solution for the systemic administration. 20 In order to circumvent the problem of poor drug-like properties of 5-ALA and its esters, we recently reported new 5-ALA prodrugs where the amino group of ALA-Hex was modified with a phosphatase-sensitive linker.…”

“…One issue with the use of 5-ALA is that it does not transverse cell membranes and other biological barriers efficiently, and to counter this several more lipophilic derivatives have been developed to improve bioavailability [23]. Fotinos et al pneumoniae with 10 M MB.…”
