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
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
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
Administration of quercetin, a common polyphenolic component of many vascular and edible plants including vegetables, fruits and tea significantly reduced the tumor volume in rats induced for mammary carcinoma using dimethyl benz (a) anthracene (DMBA). Dose response was assessed, by
