5-Aminolevulinic acid hydrochloride Chemical Properties, Uses, Production
Description
5-Aminolevulinic acid hydrochloride (5-ALA) is a naturally occurring amino acid that is an intermediate in the biosynthesis of chlorophyll and haemoglobin. It has anti-inflammatory, antioxidant and antitumour activities, and 5-Aminolevulinic acid hydrochloride-mediated sonodynamic therapy (SDT) has antitumour effects on pancreatic cancer cells. In addition, it is a visualising agent that causes high-grade gliomas to fluoresce under blue light, which can help guide surgeons in removing tumours and is considered a useful imaging tool for brain tumour resection.
Chemical Properties
white to pale yellow crystals or
Originator
Levulan Kerastick,DUSA Pharmaceuticals Inc.
Uses
Naturally occurring amino acid; precursor of tetrapyrroles in the biosynthesis of chlorophyll and heme. Antineoplastic (photosensitizer).
Uses
5-Aminolevulinic acid hydrochloride has been used as a supplement for culturing Escherichia coli cells for heme biosynthesis.
Uses
5-Aminolevulinic acid hydrochloride finds an important role as a precursor in the synthesis of tetrapyrroles such as chlorophyll and heme. It is widely utilized in photodynamic therapy of diseases namely, Pagets disease and human papillomavirus (HPV) infection-associated cervical condylomata acuminata.
Application
5-Aminolevulinic acid hydrochloride has been used to activate or inhibit heme biosynthesis in HeLa and K562 cell lines. It has also been used in photodynamic therapy in mice with A431 tumours. Clinical oral administration of 5-Aminolevulinic acid hydrochloride potentiates the antihypertensive effects associated with anaesthetics and is used in the treatment of hypertensive patients, particularly in elderly hypertensive patients receiving antihypertensive medications[1-2].
Definition
ChEBI: 5-aminolevulinic acid hydrochloride is a hydrochloride that is the monohydrochloride of 5-aminolevulinic acid. It is metabolised to protoporphyrin IX, a photoactive compound which accumulates in the skin. Used in combination with blue light illumination for the treatment of minimally to moderately thick actinic keratosis of the face or scalp. It has a role as an antineoplastic agent, a photosensitizing agent, a dermatologic drug and a prodrug. It contains a 5-ammoniolevulinic acid.
Manufacturing Process
1) Oxidation Step
2.27 g (10.0 mmol) of N-furfurylphthalimide was charged into a three-necked
glass flask equipped with an oxygen feed tube, a thermometer, and a reflux
condenser, and dissolved in 100 ml of anhydrous pyridine. After the addition
of 7.0 mg of Rose Bengal, oxygen gas was fed at a rate of 20 ml/min at 10°-
20°C under irradiation by light. A 27 W white fluorescent lamp was used as a
light source and the radiation was performed from the outside of the flask.
After 7 hours, the irradiation was terminated and the pyridine was evaporated
under reduced pressure to obtain 2.47 g of a light brown, semi-crystalline
product.
2) Reduction Step (Hydrogenation)
2.00 g of the semi-crystalline solid obtained in (1) was dissolved in 40 ml of
methanol and stirred at 50°C in a hydrogen atmosphere under atmospheric
pressure in the presence of 200 mg of 5% palladium-on-carbon catalyst.
After five hours, the reaction was terminated and the mixture was allowed to
cool to room temperature. The catalyst was removed by filtration and
methanol was evaporated to obtain 2.11 g of white crystals.
The crystals were identified to be 5-phthalimidolevulinic acid by NMR analysis.
The yield was 97%.
3) Hydrolysis Step
100 ml of 6 N hydrochloric acid was added to 2.11 g of the white crystals (2),
and the mixture was heated under reflux for 5 hours.
After evaporating the hydrochloric acid under reduced pressure, a brown solid
product was obtained and dissolved in ethanol. Acetone was added to the
solution and the crystals produced were collected by filtration to obtain 0.689
g of 5-aminolevulinic acid hydrochloride. The yield based on Nfurfurylphthalimide
was 51%.

Therapeutic Function
Photosensitizer
Biochem/physiol Actions
5-Aminolevulinic acid (5-ALA) is an intermediate in heme biosynthesis and is useful in cancer treatment. It is a non-protein amino acid. 5-ALA also has applications in the field of agriculture. It is being studied as an inducing reagent for protoporphyrin IX (PPIX) dependent fluorescence diagnosis of metastatic lymph nodes. 5-ALA is used for photodynamic therapy of diseases, such as Paget′s disease and HPV infection-associated cervical condylomata acuminata.
Purification Methods
Dry ALA-HCl in a vacuum desiccator over P2O5 overnight, then crystallise it by dissolving it in cold EtOH and adding dry Et2O. Also crystallis
