Abstract
Hypocrellins (HYPs) are natural perylene quinone derivatives from Ascomycota fungi. Based on the excellent photosensitization properties of HYPs, this work proposed a photocatalytic advanced oxidation process (PAOP) that uses HYPs to degrade rhodamine B (RhB) as a model organic pollutant. A synergistic activity of HYPs and H2O2 (0.18 mM of HYPs, 0.33% w/v of H2O2) was suggested, resulting in a yield of 82.4% for RhB degradation after 60 min under visible light irradiation at 470−475 nm. The principle of pseudo-first-order kinetics was used to describe the decomposition reaction with a calculated constant (k) of 0.02899 min−1 (R2 = 0.983). Light-induced self-degradation of HYPs could be activated under alkaline (pH > 7) conditions, promising HYPs as an advanced property to alleviate the current dilemma of secondary pollution by synthetic photocatalysts in the remediation of emerging organic pollutants.

Abstract
Photodynamic therapy (PDT) has been successfully implemented as a treatment for wet age-related macular degeneration (AMD), but very few photosensitizers have been developed for clinical use. Herein, we describe a novel formulation of liposomal hypocrellin B (LHB) that was prepared by high-pressure homogenization. The encapsulation efficiency and PDT efficacy in vitro of this new preparation were found to remain nearly constant over 1 year. Moreover, LHB is rapidly cleared from the blood, with a half-life of 2.319 ± 0.462 h and a very low serum concentration at 24 h after injection. Testing in a rat model of choroidal neovascularization (CNV) showed that leakage of blood vessels in CNV lesions was significantly reduced when LHB PDT was given at a dose of 1 mg kg(-1) along with yellow laser irradiation; the damage to the collateral retina and the retinal pigment epithelium was minimal. Skin phototoxicity assays showed that only two of the 200 mice given a 4 mg per kg dose of LHB experienced an inflammatory reaction in the auricle irradiated at 24 h after dosing. These data collectively indicate that LHB may be a safe and effective photosensitizer for vascular-targeted PDT of AMD.

Abstract
Five new dinuclear Cu(II) complexes were designed and synthesized, using hypocrellin B, a naturally occurring photosensitizer that has received extensive studies as promising photodynamic therapy (PDT) agent, as bridging ligand, and five kinds of diimine ligands, including 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), 3,4,7,8-tetramethyl-1,10-phenanthroline (tmp), dipyrido[3,2-d:2',3'-f]quinoxaline (dpq), and dipyrido[3,2-a:2',3'-c]phenazene (dppz), as terminal ligands, respectively. The Cu(2+)-HB complexes exhibit improved water solubility, enhanced absorptivity in the phototherapeutic window of 600-900 nm, and increased binding affinity toward dsDNA than their parent HB. The biologically accessible redox potential of Cu(II)/Cu(I) couple renders the five Cu(2+)-HB complexes chemical nuclease activities in the presence of reducing agent such as ascorbic acid. Moreover, the readily available redox potential of Cu(II)/Cu(I) couple switches the photodynamic activity from type II mechanism (singlet oxygen mechanism) for HB to type I mechanism (radical mechanism) for the Cu(2+)-HB complexes. Of the five Cu(2+)-HB complexes, complex 3-5 with terminal diimine ligands of tmp, dpq, and dppz, respectively, can photocleave supercoiled pBR322 DNA more efficiently than HB. These findings open a new avenue for the development of the HB derivatives with higher photodynamic activity and better clinical applicability.

Abstract
We compared the ability of pure lycopene (Lyco) versus lycopene phytocomplex (LycoC) to induce apoptosis in vitro. We found that LycoC, but not Lyco, was able to trigger apoptosis in HL60 cells, as documented by subdiploid DNA content and phosphatidylserine exposure. LycoC-induced apoptosis was associated with reactive oxygen species (ROS) generation and loss of mitochondrial transmembrane potential, suggesting that LycoC triggered apoptosis via a mitochondrial pathway. We also verified the redox state of cells by measuring glutathione (GSH) content, but only a small percentage of cells showed GSH depletion, suggesting that the loss of GSH may be a secondary consequence of ROS generation. Moreover, LycoC pretreatment effectively increased apoptosis induced by photodynamic therapy (PDT), a mode of cancer treatment using a photosensitizer and visible light. LycoC pretreatment was even more potent in improving PDT than pretreatment with ascorbic acid or alpha-tocopherol (or the two combined). Our results demonstrate that LycoC has a stronger cytotoxic effect than Lyco and is a better source of agents able to trigger apoptosis in HL60 cells and improve the efficacy of PDT in vitro.
