Chlorin derivatives sterically-prevented from self-aggregation with high antitumor activity for photodynamic therapy

In this study two new chlorin derivatives sterically prevented from aggregation were synthesised by the Diels-Alder reaction between protoporphyrin IX dimethyl ester and 1-(2-hydroxyethyl)maleimide. The compounds were fully characterised by 1H NMR, 13C NMR, UV-Vis and high-resolution mass spectroscopy (HRMS) and their photochemical properties such as singlet oxygen quantum yield (?0), fluorescence quantum yield (?f) and photodegradation were also evaluated. Furthermore, the partition coefficient (log P) revealed that these compounds present amphiphilic properties. Studies of the photodynamic action in tumour cells (HEp-2 and HeLa) and non-tumour cells (Vero) were also performed in order to confirm the photodynamic therapy (PDT) activity that was indicated by the preliminary photophysical studies. Those phototoxicity results were 55?77% higher than the results obtained with the commercial photosensitiser verteporfin. Finally, cytotoxic assays were performed with the new photosensitiser candidates and cell death was determined using fluorescence microscopy, which provided information about the mechanisms of cell death. In general, we have obtained improved and accessible compounds for PDT studies, as highlighted by the research presented here.

One pot stimuli-responsive linear waterborne polyurethanes via Diels-Alder reaction

Different strategies were used to obtain waterborne polyurethanes containing Diels-Alder moieties. In the first one (two pot), furan and maleimide end capped waterborne polyurethane dispersions were synthesized with the aim of obtaining a stimuli-responsive material after drying a mixture of both dispersions. However, the maleimide hydrolysis that took place at basic pH prevented the use of this strategy. The only way to introduce maleimide groups in the furan capped dispersions was after water removal, which limits the application. In the second strategy (one pot), a Diels-Alder adduct was introduced in the polyurethane chain. Using this strategy, stable waterborne polyurethane dispersions were successfully synthesized. Both strategies allowed the obtaining of films that according to FTIR, DSC and NMR experiments showed cyclic temperature responsive behaviour, as at high and low temperature the Diels-Alder adduct was opened and regenerated respectively. As a consequence of this reaction, the temperature increase provoked chain scission reducing both the polymer molecular weight and the viscosity. Using the one pot strategy, a Diels-Alder adduct containing polyurethane film was obtained for the first time from waterborne systems. This can be of great interest in order to obtain functional self-healing coatings with reduced volatile organic compounds (VOC).
