Abstract
Vascular responses to photodynamic therapy (PDT) may influence the availability of oxygen during PDT and the extent of tumor destruction after PDT. However, for topical PDT vascular effects are largely unknown. Arteriole and venule diameters were measured before and after hexylaminolevulinate (HAL) and aminolevulinic acid (ALA) PDT and related to the protoporphyrin IX (PpIX) concentration in the vessel wall. A mouse skin fold chamber model and an intravital confocal microscope allowed direct imaging of the subcutaneous vessels underlying the treated area. In both HAL and ALA groups over 60% of arterioles constricted completely, while venules generally did not respond, except for two larger veins that constricted partially. Arteriole vasoconstriction strongly correlated with PpIX fluorescence intensity in the arteriole wall. Total PpIX fluorescence intensity was significantly higher for HAL than ALA for the whole area that was imaged but not for the arteriole walls. In conclusion, complete arteriole vasoconstriction occurs frequently in both HAL and ALA based topical PDT, especially when relatively high PpIX concentrations in arteriole walls are reached. Vasoconstriction will likely influence PDT effect and should be considered in studies on topical HAL and ALA-PDT. Also, our results may redefine the vasculature as a potential secondary target for topical PDT.

Abstract
Photodynamic therapy (PDT) is a palliative therapy and has been used to cure cholangiocarcinoma (CC), which has a poor prognosis and limited available curative therapy. PDT was shown to improve the median survival time of advanced-stage patients. Recently, 5-aminolevulinic acid (ALA) has been used as a pro-photosensitizer, which can be transferred to intercellular protoporphyrin IX (PpIX), which is a strong photosensitizer, via the heme pathway. The main limitation of using ALA in PDT is the hydrophilic properties of ALA, which results in low cellular uptake. In this study, non-ionic surfactants, pluronic F68 (PF68) and Tween 80 (TW80), were used to address this limitation. The human CC cell line, HuCC-T1, was cotreated with ALA and different concentrations of surfactants for 4h. The effect of surfactants was evaluated by monitoring the uptake of ALA, the fluorescence intensity of PpIX, and the cell survival rate after suitable light irradiation. Cotreatment with the surfactant resulted in an increased intracellular ALA level, PpIX formation, and phototoxicity.

Abstract
Six client-owned dogs with prostate carcinoma were treated with a combination of (1) partial subcapsular prostatectomy using an Nd:YAG laser, (2) intraoperative photodynamic therapy using a halogen broad band lamp after local administration of a photosensitiser, and (3) systemic treatment with meloxicam. Median survival time was 41days (range 10-68days), which compared negatively with previous reports of subtotal laser prostatectomy combined with topical interleukin-2 administration, and photodynamic therapy alone. Despite treatment, the disease progressed locally, causing signs of stranguria to recur, and in the form of distant metastases. The recurrence of clinical signs due to the primary tumour despite photodynamic therapy is probably largely explained by insufficient penetration of light into the tissue. Better results may be obtained using other light sources (e.g. laser) and alternative techniques of light delivery, such as fibres or catheters allowing interstitial diffusion of light.

Abstract
The present contribution was dedicated to the development and characterisation of a semisolid formulation of 5-aminolevulinic acid (5-ALA), appropriate for the diagnosis and treatment of actinic keratosis in photodynamic therapy. To achieve sufficiently high concentrations of the polar substance within the living epithelium after topical application, the semisolid base was enriched with penetration enhancers. A semisolid liquid crystalline system for drug delivering was the formulation of choice. It was composed of isopropyl alcohol, dimethyl isosorbide, medium chain triglycerides, water, and Pluronic F 127 as a polyoxyethylene-polyoxypropylene surface-active block copolymer. Rheometrical investigations were performed in the oscillatory mode and showed a thermo reversible gelification behaviour of the formulation, which therefore was denoted Thermogel. Permeation studies through human stratum corneum revealed higher permeation coefficients for 5-ALA from the Thermogel than from different German Pharmacopoeia creams. For example a 7.5-fold increase in comparison with Basiscreme DAC, and a 19.5-fold increase compared to water containing hydrophilic ointment. With respect to Dolgit(R) Mikrogel, the permeation coefficient from the Thermogel was 6.4-fold higher. These results were in accordance with those of differential scanning calorimetry measurements. Thermogel disclosed the strongest interactions with stratum corneum lipids.

Abstract
PURPOSE Porphyrins synthesised from 5-aminolevulinic acid (ALA) have been successfully used for the photodiagnosis and photodynamic treatment of cancer. To find a more efficient pro-photosensitiser, we synthesised two ALA esters: R,S-ALA-2-(hydroxymethyl)tetrahydropyranyl ester (THP-ALA) and ALA-Undecanoyl ester (Und-ALA). METHODS In mice bearing a subcutaneous mammary adenocarcinoma, we studied the distribution of the porphyrins formed from these esters in tissues after systemic administration, to establish if these esters are retained in any specific tissue, which could potentially be targeted for photodynamic treatment with ALA derivatives. We also investigated the topical use of these esters. RESULTS After systemic administration, tumour and skin overlying tumour porphyrin levels were lower from the ALA esters than from ALA. Other tissues such as liver, colon, kidney, skin and spleen also accumulated less porphyrins from the esters, showing that there is no specific retention of the esters in these tissues. However, the brain was the only organ that synthesised more porphyrins from THP-ALA than from ALA. The kinetics of porphyrin synthesis from ALA esters is comparable to those from ALA in almost all tissues, showing that esterases activities are not limiting the availability of the hydrolysed ALA. Both THP-ALA and Und-ALA, applied topically on the skin over the tumour, exhibited higher selectivity than ALA for the site of application, whereas the amount of tumour porphyrin was the same from ALA and THP-ALA but lower from Und-ALA. CONCLUSIONS THP-ALA may be useful for the treatment of brain tumours after systemic administration, whereas THP-ALA and Und-ALA may be used more suitable for the treatment of superficial tumours due to their higher selectivity.

Abstract
Photodynamic therapy (PDT) is a tool for the treatment of certain cancerous and pre-cancerous conditions. The natural precursor of porphyrins 5-aminolevulinic acid (ALA) has been extensively used as a pro-photosensitiser in PDT. ALA's poor permeability has been enhanced by chemical esterification with aliphatic alcohols. Some of the ALA esters proved to be more efficient than ALA for porphyrin synthesis. In the present work we studied the nature of porphyrin synthesis regulation from the ALA esters Hexyl-ALA (He-ALA) and R,S-ALA-2-(hydroxymethyl)tetrahydropyranyl ester (THP-ALA) in an adenocarcinoma cell line. We found that He-ALA is incorporated into the cells at a higher rate, followed by THP-ALA and ALA, whereas ALA and ALA esters efflux at the same rate mediated by passive diffusion. Although ALA entrance to the cell might be regulatory at low concentrations, ALA derivative uptake is not a limiting factor. At high concentrations, the regulation of ALA conversion into porphyrins is driven by the enzyme porphobilinogenase, whereas ALA esters hydrolysis is regulated by esterases. The key conclusion of this contribution is that the use of ALA esters has to be limited to low concentrations where no regulation on porphyrin synthesis takes place.

Abstract
Photodynamic therapy is a treatment for malignant and certain non-malignant lesions that involves administration of a photosensitising drug. The use of 5-aminolaevulinic acid-induced porphyrins has become one of the most active fields of photodynamic therapy research. Since the efficacy of the treatment is somewhat limited by the hydrophilic nature of 5-aminolaevulinic acid, chemical modifications such as esterification with aliphatic alcohols have been made to induce higher porphyrin production. In an attempt to improve delivery of 5-aminolaevulinic acid to tissue, we have investigated the use of dendritic derivatives capable of bearing several drug molecules. The aim of this work was to evaluate in vivo and in vitro the efficacy of the first generation dendron, aminomethane tris-methyl 5-aminolaevulinic acid (containing three 5-aminolaevulinic acid residues) in terms of porphyrin synthesis. In LM3 cells, the dendron induced similar porphyrin levels compared to equimolar concentrations of 5-aminolaevulinic acid. Although the dendron is taken up with comparable efficiency to 5-aminolaevulinic acid, we found that there is only partial intracellular liberation of 5-aminolaevulinic acid residues. Both systemic and topical administration of the dendron to tumour-bearing mice induced higher porphyrin levels than the widely investigated hexyl ester derivative in most tissues studied, although it was not possible to surpass the levels induced by 5-aminolaevulinic acid. In conclusion, aminomethane tris-methyl 5-aminolaevulinic acid is capable of being taken up by cells efficiently, and liberating the active residues, although in vivo it was not possible to improve upon the efficacy of 5-aminolevulinic acid. Studies of accessibility and regulation of the esterases are needed to improve the design of these dendritic derivatives.

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 of 5-ALA has widely prevented its use in daily clinical practice. Although researchers were already aware of this drawback early during the development of 5-ALA-mediated PDT, only recently have well-established concepts in pharmaceutical science been adapted to investigate ways to overcome this drawback. Recently, two derivatives of 5-ALA, methylaminolevulinate (MAL) and hexylaminolevulinate (HAL), gained marketing authorization from the regulatory offices in Europe and Australia. MAL is marketed under the trade name Metvix for the treatment of actinic keratosis and difficult-to-treat basal cell carcinoma. HAL has recently been launched under the trade name Hexvix to improve the detection of superficial bladder cancer in Europe. This review will first present the fundamental concepts underlying the use of 5-ALA derivatives in PDT and FD from a chemical, biochemical and pharmaceutical point of view. Experimental evidences from preclinical data on the improvements and limits observed with 5-ALA derivatives will then be introduced. The state-of-the-art from clinical studies with 5-ALA esters will be discussed, with special emphasis placed on the process that led to the development of MAL in dermatology and to HAL in urology. Finally, we will discuss promising medical fields in which use of 5-ALA derivatives might potentially lead to further use of this methodology in photomedicine.
