Abstract
As a development of our research on biocompatible glycoconjugate probes and specifically multi-chromophoric systems, herein, we report the synthesis and early bactericidal tests of two luminescent glycoconjugates whose basic structure is characterized by two boron dipyrromethene difluoride (BODIPY) moieties and three galactoside rings mounted on an oligophenylene ethynylene (OPE) skeleton. BODIPY fluorophores have found widespread application in many branches of biology in the last few decades. In particular, molecular platforms showing two different BODIPY groups have unique photophysical behavior useful in fluorescence imaging. Construction of the complex architecture of the new probes is accomplished through a convergent route that exploits a series of copper-free Heck-Cassar-Sonogashira cross-couplings. The great emergency due to the proliferation of bacterial infections, in conjunction with growing antibiotic resistance, requires the production of new multifunctional drugs and efficient methods for their targeted delivery to control bacteria-associated diseases. Preliminary studies of the glycoconjugate properties as antibacterial agents against representatives of Gram-negative (P. aeruginosa) and Gram-positive (S. aureus) pathogens, which are associated with chronic infections, indicated significant bactericidal activity ascribable to their structural features.

Abstract
Fluorescent nucleobase and nucleic acid analogs are important tools in chemical and molecular biology as fluorescent labelling of nucleobases has applications in cellular imaging and anti-tumor activity. Boron-dipyrromethene (BODIPY) dyes exhibiting high brightness and good photostability are extensively used as fluorescent labelling agents and as type II photosensitizers for photodynamic therapy. Thus, the combination of nucleobases and BODIPY to obtain new compounds with both anti-tumor activity and fluorescent imaging functions is the focus of our research. We synthesized two new nucleobase analogs 1 and 2 by fusing the BODIPY core directly with uracil which resulted in favorable photophysical properties and high emission quantum efficiencies particularly in organic solvents. Further, we explored the newly synthesized derivatives, which possessed good singlet oxygen generation efficiencies and bio-compatibility, as potential PDT agents and our results show that they exhibit in vitro anti-tumor activities.

Abstract
The synthesis and reactivity of 3,8-dibromo-dodecafluoro-benzo-fused BOPHY 2 are reported, via SN Ar with O-, N- S- and C-nucleophiles, and in Pd(0)-catalyzed cross-coupling reactions (Suzuki and Stille). The resulting perfluoro-BOPHY derivatives were investigated for their reactivity in the presence of various nucleophiles. BOPHY 3 displays reversible color change and fluorescence quenching in the presence of bases (Et3 N, DBU), whereas BOPHY 7 reacts preferentially at the α-pyrrolic positions, and BOPHY 8 undergoes regioselective fluorine substitution in the presence of thiols. The structural and electronic features of the fluorinated BOPHYs were studied by TD-DFT computations. In addition, their spectroscopic and cellular properties were investigated; BOPHY 10 shows the most red-shifted absorption/emission (λmax 659/699 nm) and 7 the highest fluorescence (Φf =0.95), while all compounds studied showed low cytotoxicity toward human HEp2 cells and were efficiently internalized.

Abstract
BACKGROUND Photodynamic therapy (PDT) has been recognized as an alternative treatment of Candida albicans (C. albicans) infections. The aim of this study was to investigate the antifungal effect of PDT mediated by a new photosensitizer (PS) derived from BODIPY (BDP-4L) on C. albicans biofilms. METHODS C. albicans biofilms were incubated with BDP-4L of different concentrations and then irradiated at the light doses of 1.8, 3.6, 5.4, 7.2 and 9.0 J/cm2. XTT reduction assay was conducted to determine the PS concentration and PDT parameters. Confocal light scanning microscopy (CLSM) and scanning electron microscope (SEM) were used to visualize and quantify the effect of BDP-4L on C. albicans biofilms after PDT. RESULTS C. albicans biofilms were inactivated in light dose-dependent and PS concentration-dependent manners using BDP-4L as PS. Without irradiation, no inactivation effect was observed when PS concentrations varied from 5 μM to 80 μM. 40 μM PS with 3.6 J/cm2 irradiation resulted in a significant reduction of 83.8% in biofilm metabolic activities. CLSM assay demonstrated that cell viability was obviously inhibited by 82.6%. SEM images revealed ruptured and rough cell surface, indicating increased cell membrane permeability after PDT. CONCLUSIONS Our results suggested that BDP-4L mediated PDT exhibited a favorable antifungal effect on C. albicans biofilms.

Abstract
Antimicrobial photodynamic therapy (aPDT) has emerged as a novel and promising approach for the treatment of pathogenic microorganism infections. The efficacy of aPDT depends greatly on the behavior of the photosensitizer. Herein, we report the design, preparation, antimicrobial photodynamic activities, as well as structure-activity relationships of a series of photosensitizers modified at the meso position of a 1,3,5,7-tetramethyl BODIPY scaffold with various pyridinyl and pyridinium moieties. The photodynamic antimicrobial activities of all photosensitizers have been tested against Staphylococcus aureus, Escherichia coli, Candida albicans, and Methicillin-resistant S. aureus (MRSA). The methyl meso-(meta-pyridinium) BODIPY photosensitizer (3c) possessed the highest phototoxicity against these pathogens at minimal inhibitory concentrations (MIC) ranging from 0.63 to 1.25 μM with a light dose of 81 J/cm2. Furthermore, 3c exhibited an impressive antimicrobial efficacy in S. aureus-infected mice wounds. Taken together, these findings suggest that 3c is a promising candidate as the antimicrobial photosensitizer for combating pathogenic microorganism infections.

Abstract
Oxidative C-H/C-H coupling reactions of dipyrromethanes with azines in the presence of a heterophase oxidative photocatalytic system (O2/TiO2/visible light irradiation) were carried out. As a result of cyclization of obtained compounds with boron trifluoride etherate, new hetaryl-containing derivatives of 4,4-difluoro-4-boron-3a,4a-diaza-s-indacene were synthesized. For the obtained compounds, absorption and luminescence spectra, quantum yields of luminescence as well as cyclic volt-amperograms were measured.

We report the synthesis and photophysical properties of a neutral BODIPY photosensitizing copolymer (poly-8-(4-hydroxymethylphenyl)-4,4-difluoro-2,6-diethynyl-4-bora-3a,4a-diaza-s-indacene) containing ethynylbenzene links between the BODIPY units. The copolymer absorbs further towards the red in the UV-vis spectrum compared to the BODIPY precursor. Photolysis of the polymer produces a singlet excited state which crosses to the triplet surface in less than 300 ps. This triplet state was used to form singlet oxygen with a quantum yield of 0.34. The steps leading to population of the triplet state were studied using time-resolved spectroscopic techniques spanning the pico- to nanosecond timescales. The ability of the BODIPY polymer to generate a biocidal species for bactericidal activity in both solution- and coating-based studies was assessed. When the BODIPY copolymer was dropcast onto a surface, 4 log and 6 log reductions in colony forming units/ml representative of Gram-positive and Gram-negative bacteria, respectively, under illumination at 525 nm were observed. The potent broad-spectrum antimicrobial activity of a neutral metal-free copolymer when exposed to visible light conditions may have potential clinical applications in infection management.

Abstract
Boron-dipyrromethene derivatives, including cationic and iodinated analogs, were obtained and subjected to physicochemical and in vitro photodynamic activity studies. Iodinated derivatives revealed a substantial heavy atom effect manifested by a bathochromic shift of the absorption band by about 30 nm and fluorescence intensity reduced by about 30-35 times, compared to that obtained for non-iodinated ones. In consequence, singlet oxygen generation significantly increased with ΦΔ values in the range 0.69-0.97. The in vitro photodynamic activity was evaluated on Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli, and on human androgen-sensitive prostate adenocarcinoma cells (LNCaP). The novel cationic, iodinated BODIPY, demonstrated the highest activity toward all studied cells. An excellent cytotoxic effect was found against LNCaP cells with an IC50 value of 19.3 nM, whereas the viability of S. aureus was reduced by >5.6 log10 at 0.25 μM concentration and by >5.3 log10 in the case of E. coli at 5 μM. Thus, this analog seems to be a very promising candidate for the application in both anticancer and antimicrobial photodynamic therapy.

Abstract
A necessity of therapeutics against antibiotic-resistant bacteria has led to a search for novel antibacterial compounds. The strategy to isolate compounds from non-microbial sources is the key to prevent antibiotic resistance. Here, we report isolation and characterization of an antibacterial coumarin derivative, 4-diphenylamino 3-iodo coumarin (4-DPA3IC) from a traditional drug formulation. The compound elicited high activity against MDR strains of S. aureus. Targets were identified through computational methods encompassing modules of Schrodinger 10.4. The 4-DPA3IC targeted S. aureus DNA gyrase enzyme B subunit. Amino acid residues and interactions involved here are totally different from those of novobiocin and clorobiocin. The validation was done by in vitro DNA gyrase supercoiling inhibition assay. This study proved 4-DPA3IC could potentially act against novobiocin and cholorbiocin resistant strains of S. aureus. Thus, the 4-DPA3IC is a unique inhibitor of bacterial DNA gyrase due to its plant origin as compared to other reported inhibitors.

Abstract
We report a series of alkyne-functionalized meso-aryl boron dipyrrin (BODIPY) molecular rotors sensitive to viscosity. The planar and twisted conformation within the molecular structure decides the viscosity-dependent behavior. The variations in fluorescence lifetime and intensity were appreciable to the local viscosity. Hence, the dye has been successfully employed in the enumeration of microbes by considering the proportionate fluorescence intensity of the BODIPYs as an index of the number of cells per mL. With increasing cells per mL, the viscosity of the bacterial solution is increased. Consequently, the fluorescence intensity of the sample containing BODIPY tends to increase due to the restricted rotation in the viscous medium. The BODIPY probe offers high sensitivity and is easier than other conventional techniques of colony-forming unit (CFU) determination. The theoretical studies indicate that intramolecular charge transfer is responsible for the enhanced fluorescence intensity in a highly viscous solvent.

Abstract
Photodynamic antimicrobial chemotherapy (PACT) is an effective strategy to inactivate pathogenic and resistant microbes. However, pan-microbial photoinactivation has hardly achieved. In this manuscript, we built anti-microbial PSs based on 2,6-diiodo-1,3,5,7-tetramethyl BODIPY (2I-BDP) using anchoring strategy through modifications on boron atom with bis-cationic moieties. With appropriate bis-cationic anchoring, we could achieve effective PACT for pan-microbial photoinactivation via straight forward modifications. Our studies suggested that integration of an efficient photosensitizer, good amphiphilicity, as well as tight interaction with microbial membrane could be essential for effective PACT.

Abstract
A synthetic strategy to BODIPY dyes is presented giving access to a range of new compounds relevant in the context of antimicrobial photodynamic therapy (aPDT). BODIPYs with the 8-(4-fluoro-3-nitrophenyl) and the 8-pentafluorophenyl substituents were used for the synthesis of new mono- and dibrominated BODIPYs. The para-fluorine atoms in these electron-withdrawing groups facilitate functional modification via nucleophilic aromatic substitution (SNAr) with a number of amines and thio-carbohydrates. Subsequently, the antibacterial phototoxic activity of these BODIPYs has been assessed in bacterial assays against the Gram-positive germ S. aureus and also against the Gram-negative germ P. aeruginosa. The bacterial assays allowed to identify substitution patterns which ensured antibacterial activity not only in phosphate-buffered saline (PBS) but also in the presence of serum, hereby more realistically modelling the complex biological environment that is present in clinical applications.

Abstract
BODIPYs with 3-thienyl and 4-acetamido phenyl groups substituted at the meso-position are subjected to regioselective bromination using three equivalents of [Formula: see text]-bromosuccinimide (NBS) to yield their 2-mono and 2,6-di bromoderivatives. Their photophysical, electrochemical and antimicrobial properties are investigated. This paper presents a mechanistic investigation of the antibacterial effect of brominated BODIPYs, particularly against Staphylococcus aureus. Fluorescence microscopic images reveal that the compounds are internalized effectively within the bacterial cells, making it an ideal antibacterial drug. Morphological analysis of the bacterial cells after the treatment with the test compounds showed that the compounds did not affect the cell membrane or cell wall and the antibacterial effect of these compounds is achieved via a different mechanism. The most effective compound was selected to explore the target of action. Molecular docking studies were performed on 22 selected proteins in S. aureus and the in silico results were validated by in vitro experiments. It was observed that the supercoiling activity of DNA gyrase was completely inhibited by the 2,6-dibromo-1,3,5,7-tetramethyl-8-(4-acetamido)-4-bora-3a,4a-diaza-[Formula: see text]-indacene, 3c by forming H-bonds with the ASP 81 residue of the enzyme.
