Resumen:
Chemical study of H. lycioides allowed the isolation of seven anthraquinones, three of them reported as novel for this family of compounds [1]. It was demonstrated that five of them: soranjidiol (Sor), 5-chlorosoranjidiol (5-ClSor), bisoranjidiol (Bisor), lycionine (Lyc) and 7-chlorobisoranjidiol (7-ClBisor) (Fig. 1) are potencial photosensitizers compounds to be applied in Photodynamic Therapy (PDT) [1,2]. Nevertheless, photoinduced color changes (either by degradation or molecular rearrangements) of photosensitizer solutions is one of the critical requirements necessary for efficent PDT. Hence, in this report we compare the UV-Vis spectral changes of the following natural monomeric and dimeric dihydroxyanthraquinones compounts DHAQs:
