We evaluated the influence of near-ultraviolet light (UVA) on the cytotoxicity and genotoxicity of 7 polycyclic aromatic hydrocarbons (PAH) in larvae of the amphibian Pleurodeles waltl. Benz[a]anthracene (BA), 7,12-benz[a]anthraquinone (BAQ) and anthracene (Ac) proved to be lethal at low doses

The spectroscopy and photophysics of several hypericin and helianthrone derivatives were studied in methanol and when bound to liposomes. The singlet oxygen quantum yields (phi(delta)) were measured indirectly relative to Rose Bengal and hematoporphyrin IX, employing 9,10-dimethylanthracene as a singlet
Drug and chemical toxicology, 31(4), 459-471 (2008-10-14)
A single intratracheal instillation of 9,10-dimethyl benz(a)anthracene (DMBA) at 3 different doses of 5, 10, and 20 mg/kg body weight to Balb/c mice for 12 weeks had caused a significant incidence of pulmonary tumors along with inflammatory changes. The number

In this work we investigate the localization and photophysical properties of twelve synthetically derived chlorins in artificial membranes, with the goal of designing more effective photosensitizers for photodynamic therapy (PDT). The studied chlorins incorporate substituents of varying lipophilicity at the

Two new sensitizers are introduced for a potential use in photodynamic therapy: Zn(2+)- and MG(2+)-tetrabenzoporphyrin (ZnTBP and MgTBP). A comparative study of the quantum yields of singlet oxygen generation (phi delta) of hematoporphyrin derivative (HpD), Photofrin II (PF-II), Zn(2+)-phthalocyanine tetrahydroxyl
