Description: Aminolevulinic acid, also known as ALA, is a topically administered metabolic precursor of protoporphyrin IX. After topical administration, aminolevulinic acid (ALA) is converted to protoporphyrin IX (PpIX) which is a photosensitizer. When the proper wavelength of light activates protoporphyrin IX, singlet oxygen is produced, resulting in a local cytotoxic effect. In 1999, FDA approved this drug for for actinic keratosis.

Biological target: | 5-Aminolevulinic Acid HCl is an intermediate in the porphyrin synthesis pathway, used as a photosensitizing agent and a antineoplastic agent. |
In vitro activity: | Expression of GPX4 and HMOX1 in pathologic specimens of 97 ESCC (esophageal squamous cell carcinoma) patients was examined and real-time polymerase chain reaction (RT-PCR), RNA microarray, and Western blotting analyses were used to evaluate the role of 5-ALA in ferroptosis in vitro. The results showed that upregulation of GPX4 and downregulation of HMOX1 were poor prognostic factors in ESCC. In an RNA microarray analysis of KYSE30, ferroptosis was one of the most frequently induced pathways, with GPX4 suppressed and HMOX1 overexpressed by 5-ALA treatment. Furthermore, 5-ALA led to an increase in lipid peroxidation and exerted an antitumor effect in various cancer cell lines.

In vivo activity: | The role of 5-ALA in ferroptosis was evaulated by its effect on an ESCC (esophageal squamous cell carcinoma) subcutaneous xenograft mouse model. In vivo, 5-ALA suppressed GPX4 and overexpressed HMOX1 in tumor tissues and led to a reduction in tumor size.
