The electronic structure of crystalline perylene has been investigated within the framework of density functional theory including van der Waals interactions. The computations of the lattice parameters and cohesive energy have good agreement with experimental values. We have also calculated

Hypericin (Hyp) is a promising photosensitizer for photodiagnostic and photodynamic therapy of cancer. However, Hyp has a large conjugated system and in aqueous solutions forms insoluble aggregates which do not possess biological activity. This makes intravenous injection of Hyp problematic

Insertion of a programmed temperature vaporizing (PTV) injector under conditions of concurrent solvent recondensation (CSR) into the on-line HPLC-GC interface for on-column transfer (such as the retention gap technique with partially concurrent eluent evaporation) enables filtering off high boiling or

We sought to reduce the radioactive intestinal waste after intravenous injection of necrosis avid iodine-131-labeled hypericin in dual-targeting anticancer radiotherapy and to study its pharmacokinetics in rats using a newly designed catheter. Iodine-123-labeled hypericin was prepared with iodogen as oxidant
Reply to the 'Comment on "The structure and formation of hydrogen-bonded molecular networks on Au(111) surfaces revealed by scanning tunnelling and torsional-tapping atomic force microscopy"' by I. Cebula, M. T. Räisänen, R. Madueno, B. Karamzadeh and M. Buck, Phys. Chem. Chem. Phys., 2013, 15, DOI: 10.1039/c3cp50754h.

Cancer cells evade replicative senescence by re-expressing telomerase, which maintains telomere length and hence chromosomal integrity. Telomerase inhibition would lead cancer cells to senesce and therefore prevent cancer cells from growing indefinitely. G-quadruplex ligands can attenuate telomerase activity by inducing

Different generations of perylenediimide-cored dendrimers with peripheral amine groups were synthesized. All these water-soluble dendrimers could rapidly internalize into live cells with high efficacy of gene transfection and low cytotoxicity. Increasing dendrimer generation increased their ability for gene transfection.

Cercospora leaf spot disease, caused by the fungus Cercospora beticola, is the most destructive foliar disease of sugar beets (Beta vulgaris) worldwide. Cercosporin, a light-inducible toxin, is essential for necrosis of the leaf tissue and development of the typical leaf

A reactive template method was used to fabricate alginate-based hydrogel microcapsules. The uniform and well-dispersed hydrogel capsules have a high drug loading capacity. After they are coated by a folate-linked lipid mixture on the surface, the capsules possess higher cell

Osteoclast-induced bone resorption and wear-particle-induced osteolysis leads to prosthetic loosening, one of the most common causes of joint implant failure, resulting in revision surgery. Thus, inhibition of osteoclastic bone resorption, which further prevents wear particle-induced osteolysis, is a potential treatment

Herein, we describe the first report on a new class of disk-shaped and quite monodisperse water-soluble nanomaterials that we named glyconanosomes (GNS). GNSs were obtained by sliding out the cylindrical structures formed upon self-organization and photopolymerization of glycolipid 1 on

We performed fluorescence (FL) and fluorescence excitation (FLE) spectroscopy on the model molecule perylene-3,4,9,10-tetracarboxyl acid dianhydride (PTCDA) for very low coverages (below 1% of a monolayer) on thin (100) oriented KCl films. Two different states of PTCDA molecules can be

The complex of Hypocrellin A with Al(3+) is prepared in water solution by a facile method. The water-solubility and stability of complexes are improved. Irradiation of Al(3+)-HA complex results in higher efficient generation of singlet oxygen ((1)O2) and photocleavage ability

Based on the soil-to-seeds principle, we explored the small-molecular sequential dual-targeting theranostic strategy (SMSDTTS) for prolonged survival and imaging detectability in a xenograft tumor model. Thirty severe combined immunodeficiency (SCID) mice bearing bilateral radiation-induced fibrosarcoma-1 (RIF-1) subcutaneously were divided into

The self-assembly behavior of an achiral perylene bisimide (PBI) organogelator that bears two 3,4,5-tridodecyloxybenzoylaminoethyl substituents at the imide positions has been investigated in chiral solvents (R)- and (S)-limonene in great detail by circular dichroism (CD) spectroscopy and atomic force microscopy

From cultures of Cercospora piaropi, a phytopathogenic fungus isolated from symptomatic leaves of water hyacinth was obtained a red compound, which, according to the spectroscopic data, was epi-cercosporin. It showed in vitro antiproliferative activity against the panel of human solid

PVP-Hypericin (PVP: polyvinylpyrrolidone) is a potent anti-cancer photosensitizer for photodynamic diagnosis (PDD) and therapy (PDT). However, cellular targets and mechanisms involved in the cancer-selectivity of the photosensitizer are not yet fully understood. This paper gives new insights into the differential
