5-Aminolevulinic Acid——Clinical Significance
Sep 30, 2017

δ-Aminolevulinic acid (also dALA, δ-ALA, 5ala or 5-aminolevulinic acid) is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals and chlorophyll in plants.

In plants, production of δ-ALA is the step on which the speed of synthesis of chlorophyll is regulated. Plants that are fed by external δ-ALA accumulate toxic amounts of chlorophyll precursor, protochlorophyllide, indicating that the synthesis of this intermediate is not suppressed anywhere downwards in the chain of reaction. Protochlorophyllide is a strong photosensitizer in plants.

 

Being a precursor of photosensitizer, 5-aminolevulinic acid uses are also used as an agent for photodynamic therapy.


Cancer diagnosis

Photodynamic detection is the use of photosensitive drugs with a light source of the right wavelength for the detection of cancer, using fluorescence of the drug. 5-Aminolevulinic acid, or derivatives thereof, can be used to visualize bladder cancer by fluorescence imaging.


Cancer treatment with PDT

Photodynamic therapy (PDT) treatment possibilities include those for cancer of the prostate, breast, giant BCC (skin), cervix, recurrent bladder, vulvar, brain (human glioblastoma cells), HPV, lung, stomach, head and neck, penis, and colon, as well as those for leukemia, Barrett's esophagus, squamous cell carcinoma(SCC), Bowen's disease, and other types of cancer.

 

Fluorescence-guided surgery (e.g. for cancer)

It elicits synthesis and accumulation of fluorescent porphyrins (protoporphyrin IX) in epithelia and neoplastic tissues, among them malignant gliomas. It is used to visualise tumorous tissue in neurosurgical procedures. Studies since 2006 have shown that the intraoperative use of this guiding method may reduce the tumour residual volume and prolong progression-free survival in patients suffering from this disease. The US FDA approved aminolevulinic acid hydrochloride (ALA HCL) for this use in 2017.
