Progressive Cationic Functionalization of Chlorin Derivatives for Antimicrobial Photodynamic Inactivation and Related Vancomycin Conjugate

10.1039/C7PP00389G

2018-04-12

It is known that multiple cationic charges are required to produce broad-spectrum antimicrobial photosensitizers (PS) for photodynamic inactivation (aPDI) or photodynamic therapy of bacteria and fungi. In the present study we describe the synthesis and aPDI t...

Photo-induced anticancer activity and singlet oxygen production of prodigiosenes

10.1039/C8PP00060C

2018-04-12

The photo-induced cytotoxicity of prodigiosenes is reported. One prodigiosene represents a synthetic analogue of the natural product prodigiosin, and two are conjugated to molecules that target the estrogen receptor (ER). A comparison of incubation and irradi...

The excited states interaction of safranine-O with low generation carboxyl terminated PAMAM dendrimers in aqueous medium.

10.1039/C8PP00039E

2018-04-11

The interaction of the singlet and triplet excited states of the synthetic dye safranine-O with carboxyl-terminated poly(amidoamine) (PAMAM) dendrimers was investigated in buffer solution at pH 8. Low half-generation PAMAM dendrimers (G -0.5; G +0.5: G 1.5) w...

Plasmonic Photocatalysis: Complete Degradation of Bisphenol A by Gold Nanoparticle-Reduced Graphene Oxide Composite under Visible Light

10.1039/C8PP00012C

2018-04-10

Bisphenol A is a well known endocrine disruptor that comes from plastic/epoxy resin-based consumer products, pollutes our environment and responsible for various human diseases. Thus its removal from water/food/environment is becoming a challenging issue. Her...

Effect of Solvent Relaxation Time Constants on Free Energy Gap Law for Ultrafast Charge Recombination Ensuing Photoinduced Charge Separation

10.1039/C7PP00464H

2018-04-04

To elucidate the regularities inherent in the kinetics of ultrafast charge recombination ensuing photoinduced charge separation in donor-acceptor dyads in solutions, the simulations of the kinetics have been performed within the stochastic multichannel point-...

Effect of solar ultraviolet radiation exposure on serum 25(OH)D concentration: a pilot randomised controlled trial

10.1039/C7PP00378A

2018-03-29

Sunlight generates vitamin D, but there are scant human data from randomised trials on which to base health policy advice about how much sun exposure is necessary to change 25(OH)D concentrations. The purpose of the study was to evaluate the feasibility of us...

Sunlight-charged heterojunction TiO2 and WO3 particle-embedded inorganic membranes for night-time environmental applications

10.1039/C7PP00451F

2018-03-29

A metal oxide-heterojunction photocatalyst is developed to harvest sunlight, store the energy in electrons, and apply the stored energy in water treatment. Light-absorbing nanoparticular and nanotubular TiO2 are hybridized with electron-storing WO3 at differe...

Photodynamic effect of zinc porphyrin on the promastigote and amastigote forms of Leishmania braziliensis

10.1039/C7PP00458C

2018-03-27

Leishmaniasis is a neglected disease present in more than 88 countries. The currently adopted chemotherapy faces challenges related to side effects and the development of resistance. Photodynamic therapy (PDT) is emerging as a therapeutic modality for cutaneo...

Sequence dependence on DNA photochemistry: a computational study of photodimerization pathways in TpdC and dCpT dinucleotides

10.1039/C8PP00040A

2018-03-23

The excited states involved in the main photodimerization paths in TpdC and dCpT are mapped by PCM/TD-M052X calculations, considering different dinucleotide conformers. As for TT steps, a cyclobutane pyrimidine dimer (CPD) is formed on the PES of the lowest e...

Photochromism and the fluorescence properties of bisbenzothienylethene and S,S,S′,S′-tetraoxide derivatives with dual conjugated fluorescent groups on their side chains

10.1039/C8PP00050F

2018-03-23

Two photochromic bisbenzothienylethenes with two fluorescent (4-((2,5-bis(dodecyloxy)-4-(phenylethynyl)phenyl)ethynyl)phenyl) units and their disulfone derivatives were synthesized, and their photochromic and fluorescence properties were examined. Bisbenzothi...
