In vitro Studies of Antitumor Effect, Toxicity/Cytotoxicity and Skin Permeation/Retention of a Green Fluorescence Pyrene-based Dye for PDT Application. Photochem Photobiol 2020; 97:408-415. [PMID: 32967040 DOI: 10.1111/php.13335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 08/27/2020] [Accepted: 09/14/2020] [Indexed: 11/28/2022]
Abstract
Photosensitizers (PS) are compounds that can generate reactive oxygen species under irradiation of appropriate light and are widely used in photodynamic therapy (PDT). Currently, topical PDT is an effective treatment for several skin diseases, including bacterial infections, fungal mycoses and psoriasis. In addition, PDT is also used to treat nonmelanoma skin cancer and can be a potential tool for melanoma, associated with other treatments. In this work, we evaluated the antitumor photoactivity of a new pyrene-based PS (TPPy) by using the murine melanoma cell line (B16F10). The in vitro permeation/retention tests in porcine ear skin were also performed in order to evaluate the potential application of the PS for topical use in skin cancer. Moreover, to determine the toxicity in vivo, we used the Galleria mellonella as an alternative animal model of study. The results showed that TPPy is a promising PS for application in PDT, with potential antitumor photoactivity (IC50 6.5 μmol L-1 ), absence of toxicity in the G. mellonella model at higher concentration (70.0 mmol L-1 ) and the accumulation tendency in the epidermis plus dermis sites (165.20 ± 4.12 ng cm-2 ).

Abstract
We present a patient with virus-associated hemorrhagic cystitis who underwent kidney and allogenic hematopoietic stem cell transplantations (allo-HSCT). Six months post-allo-HSCT, adenovirus hemorrhagic cystitis occurred, which has been in remission after a single dose of intravesical cidofovir. This might cause prolonged neutropenia and nephrotoxicity, suggesting cidofovir absorption in the blood.

Abstract
Aim: The purpose of this study was to formulate carbopol hydrogels containing eugenol-loaded solid lipid nanoparticles (EG–SLNs) for epidermal targeting to treat fungal infections in skin. Materials & methods: EG–SLNs were incorporated into carbopol hydrogels and the physiochemical characteristics of EG–SLN in hydrogels were investigated by dynamic light scattering, transmission electron microscopy and atomic force microscopy. Rheological behavior and mechanical properties of hydrogels were also studied before and after incorporation of EG–SLNs. The epidermal-targeting ability of EG–SLN-enriched hydrogels was evaluated by estimation of eugenol in the epidermis of human cadaver skin. An occlusion (hydration) study was also performed to elucidate the mechanism of epidermal targeting of EG–SLN-enriched hydrogels. Results: The particle size (d90) and morphology of EG–SLNs were not significantly changed after incorporation into the hydrogel. EG–SLN of stearic acid-enriched hydrogels follow the Carreau model that describes pseudoplastic flow. The hydrogel containing EG–SLN of stearic acid and of Compritol® (Gattefose, Mumbai, India) showed significantly greater accumulation of eugenol in the epidermis (62.65 ± 4.35 and 52.86 ± 3.76 µg/cm2, respectively) than that of eugenol–hydroxypropyl-β–cyclodextrin complex in hydrogel (9.77 ± 1.16 µg/cm2) and almond oil solution of eugenol (3.45 ± 0.6 µg/cm2). The occlusion study demonstrated greater hydration of human cadaver skin treated with EG–SLN-enriched hydrogel compared with that of hydrogel and intact skin. Conclusion: Hydrogels containing EG–SLNs could be a promising formulation for epidermal targeting to treat fungal infections in skin.

Abstract
Background: A sensitive analytical method is needed for assessing penetration of topically applied peptides for in vitro skin-penetration studies. Results: A rapid hydrophilic interaction LC (HILIC)–MS/MS method for analyzing the polar peptides Ac-EEMQRR-amide and H2N-EEMQRR-amide in various skin layers and matrices has been developed and evaluated. The matrices included emulsion, receptor fluids, cotton-tipped applicators, stratum corneum tape strips, epidermis and dermis of the skin. Stable isotopically labeled analogues were used as internal standards to correct for recovery and matrix effects. A HILIC-SPE procedure was optimized to minimize significant ion suppression in the more complex matrices. Conclusion: This HILIC–MS/MS method is applicable to the determination of Ac-EEMQRR-amide and H2N-EEMQRR-amide in complex skin samples and other matrices generated during in vitro skin-penetration studies.

Abstract
A fluorometric analytical method was developed for quantification of protoporphyrin IX (PpIX) in skin samples and receptor phase solution after in vitro cutaneous penetration/permeation studies. Analytical conditions used were: excitation and emission wavelengths: 400 nm and 632 nm; bandwidth: 0.5 nm; excitation and emission slits: 10/10. PpIX was recovered from two different layers of skin, the stratum corneum (SC) and the epidermis plus dermis ([E+D]), by vortex homogenization, probe and bath sonication, using DMSO as an extraction solvent. The detection and quantification limits were 0.002 and 0.005 μg/mL, respectively. The assay was linear from 0.005 - 0.5 μg/mL. The within-day and between-day assay precision and accuracy in DMSO and receptor phase solution were each studied at the two concentration levels 0.04 and 0.2 μg/mL, and 0.01 and 0.08 μg/mL, respectively. The coefficients of variation and deviation from the theoretical values were lower than 5%. The skin recovery of PpIX from SC and [E+D] layers using two different concentrations (0.5 and 1.0 μg/mL) were all above 90.0%. The method described has potential application to in vitro penetration/permeation studies of PpIX using porcine skin as a biological membrane model.

Abstract
A simple HPLC/UV method for the determination of the transdermal permeation and dermal penetration of a broad-spectrum antiviral drug adefovir (PMEA) was developed. The separation was achieved on a C18 column with the mobile phase composed of 10 mM KH2PO4 and 2 mM Bu4NHSO4 at pH 6.0 and 7% acetonitrile. The method was validated with respect to selectivity, linearity (0.1-50 microg/ml), precision, accuracy, and stability. Transdermal permeation of 2% PMEA was studied in vitro using the Franz diffusion cell and porcine skin. The flux values were 1.8, 3.0, and 0.6 microg/cm2/h from aqueous donor samples at pH 3.4 and 7.4, and isopropyl myristate, respectively. The respective skin concentrations at 48 h were 294, 263, and 971 microg/g from these vehicles. These results will serve as a lead for further studies on transdermal and topical delivery of antivirals from the group of acyclic nucleoside phosphonates.
