Comparative experimental study of 5-ALA and 5-ALA hexyl ester specific activity

open access: yesBiomedical Photonics, 2018
A comparative experimental study of the specific activity of drugs based on 5-aminolevulinic acid (5-ALA) and its hexyl ester (5-ALA HE) was carried out. Their ability to induce the synthesis of photoactive protoporphyrin IX in the healthy tissues of the

Systematic Review and Meta-Analysis of In Vitro Anti-Human Cancer Experiments Investigating the Use of 5-Aminolevulinic Acid (5-ALA) for Photodynamic Therapy

open access: yesPharmaceuticals, 2021
5-Aminolevulinic acid (5-ALA) is an amino acid derivative and a precursor of protoporphyrin IX (PpIX). The photophysical feature of PpIX is clinically used in photodynamic diagnosis (PDD) and photodynamic therapy (PDT).

Cancer stem cell populations are resistant to 5-aminolevulinic acid-photodynamic therapy (5-ALA-PDT) [PDF]

open access: yesScientific Reports
Photodynamic therapy (PDT) is a minimally invasive treatment approved for many types of cancers. PDT involves the administration of photoactive substances called photosensitizers (PS) that selectively accumulate in cancer cells and are subsequently ...

5-ALA fluorescence in indeterminate grade gliomas [PDF]

open access: yesNeurosurgical Focus: Video, 2022
5-Aminolevulinic acid (5-ALA) is a useful and well-established adjunct for glioblastoma surgery. A growing body of evidence has revealed the potential utility of 5-ALA in grade II and grade III glioma patients as well. However, reliable means of identifying in whom fluorescence will occur have not been established.
