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.

Synthesis and In Vitro Photodynamic Activity of Cationic Boron Dipyrromethene-Based Photosensitizers against Methicillin-Resistant Staphylococcus aureus. Biomedicines 2020; 8:E140. [PMID: 32485946 PMCID: PMC7344895 DOI: 10.3390/biomedicines8060140] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Revised: 05/25/2020] [Accepted: 05/26/2020] [Indexed: 01/07/2023] Open
Abstract
A series of cationic boron dipyrromethene (BODIPY) derivatives were synthesized and characterized with various spectroscopic methods. Having the ability to generate singlet oxygen upon irradiation, these compounds could potentially serve as photosensitizers for antimicrobial photodynamic therapy. Of the five BODIPYs being examined, the dicationic aza-BODIPY analogue (compound 5) demonstrated the highest potency against a broad spectrum of clinically relevant methicillin-resistant Staphylococcus aureus (MRSA), including four ATCC-type strains (ATCC 43300, ATCC BAA-42, ATCC BAA-43, and ATCC BAA-44), two strains carrying specific antibiotic resistance mechanisms [-AAC(6')-APH(2") and RN4220/pUL5054], and ten non-duplicate clinical strains from hospital- and community-associated MRSAs of the important clonal types ST239, ST30, and ST59, which have previously been documented to be prevalent in Hong Kong and its neighboring countries. The in vitro anti-MRSA activity of compound 5 was achieved upon irradiation with near-infrared light (>610 nm) with minimal bactericidal concentrations (MBCs) ranging from 12.5 to 25 µM against the whole panel of MRSAs, except the hospital-associated MRSAs for which the MBCs were in the range of 50-100 µM. Compound 5 was significantly (p < 0.05) more potent than methylene blue, which is a clinically approved photosensitizer, indicating that it is a promising antimicrobial agent that is worthy of further investigation.

Abstract
Positron emission tomography (PET) is a molecular imaging technology that provides quantitative information about function and metabolism in biological processes in vivo for disease diagnosis and therapy assessment. The broad application and rapid advances of PET has led to an increased demand for new radiochemical methods to synthesize highly specific molecules bearing positron-emitting radionuclides. This Review provides an overview of commonly used labeling reactions through examples of clinically relevant PET tracers and highlights the most recent developments and breakthroughs over the past decade, with a focus on 11 C, 18 F, 13 N, and 15 O.

Abstract
We report the nuclear and optical in vitro and in vivo imaging of SKOV-3 cells by targeting HER2 with a bimodal trastuzumab conjugate. Previously, we have shown that desferrichrome derivatives provide a robust and versatile radiolabeling platform for the radioisotope zirconium-89. Here, we appended silicon-rhodamine functionalized linear desferrichrome to trastuzumab. This construct was radiolabeled and used to image cellular binding and antibody uptake in vitro and in vivo. The robust extinction coefficient of the SiR deep-red emissive fluorophore enables direct quantification of the number of appended chelators and fluorophore molecules per antibody. Subsequent radiolabeling of the multifunctional immunoconjugate with 89Zr was achieved with a 64 ± 9% radiochemical yield, while the reference immunoconjugate desferrioxamine (DFO)-trastuzumab exhibited a yield of 84 ± 9%. In vivo PET imaging (24, 48, 72, and 96 h post injection) and biodistribution experiments (96 h post injection) in HER2+ tumor bearing mice revealed no statistically significant difference of the two 89Zr-labeled conjugates at each time point evaluated. The bimodal conjugate permitted successful in vivo fluorescence imaging (96 h post injection) and subsequent fluorescence-guided, surgical resection of the tumor mass. This report details the first successful application of a fluorophore-functionalized desferrichrome derivative for targeted imaging, motivating further development and application of this scaffold as a multimodal imaging platform.

Abstract
A simple and rapid method for 18 F radiolabelling of [GaF3 (BnMe2 -tacn)] by 18 F/19 F isotopic exchange is described. The use of MeCN/H2 O or EtOH/H2 O (75:25) and aqueous [18 F]F- (up to 200 MBq) with heating (80 °C, 10 min) gave 66±4 % 18 F incorporation at a concentration of 268 nm, and 37±5 % 18 F incorporation at even lower concentration (27 nm), without the need for a Lewis acid promoter. A solid-phase extraction method was established to give [Ga18 F19 F2 (BnMe2 -tacn)] in 99 % radiochemical purity in an EtOH/H2 O mixture.

Abstract
A new generation of monomolecular imaging probes (MOMIP) based on a distyryl-BODIPY (BODIPY=boron-dipyrromethene) coupled with three DOTA macrocycles has been prepared (DOTA=1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid). The MOMIP presents good fluorescence properties and is very stable in serum. The bimodal probe was conjugated to trastuzumab, and an optical in vivo study showed high accumulation of the imaging agent at the tumor site. (111) In radiometallation of the bioconjugate was performed in high radiochemical yield, highlighting the potential of this new BODIPY-chelators derivative as a bimodal imaging probe.

Synthesis and Evaluation of [(18) F]-Ammonium BODIPY Dyes as Potential Positron Emission Tomography Agents for Myocardial Perfusion Imaging. Chemistry 2016; 22:12122-9. [PMID: 27405398 DOI: 10.1002/chem.201601972] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2016] [Revised: 06/06/2016] [Indexed: 01/06/2023]
Abstract
Recently, we demonstrated the potential of a [(18) F]-trimethylammonium BODIPY dye for cardiac imaging. This is the first example of the use of the [(18) F]-ammonium BODIPY dye for positron emission tomography (PET) myocardial perfusion imaging (MPI). In this report, we extend our study to other ammonium BODIPY dyes with different nitrogen substituents. These novel ammonium BODIPY dyes were successfully prepared and radiolabeled by the SnCl4 -assisted (18) F-(19) F isotopic exchange method. The microPET results and the biodistribution data reveal that nitrogen substituent changes have a significant effect on the in vivo and pharmacological properties of the tracers. Of the novel [(18) F]-ammonium BODIPY dyes prepared in this work, the [(18) F]-dimethylethylammonium BODIPY is superior in terms of myocardium uptake and PET imaging contrast. These results support our hypothesis that the ammonium BODIPY dyes have a great potential for use as PET/optical dual-modality MPI probes.

Abstract
The combination of the two complementary imaging modalities (19) F magnetic resonance imaging (MRI) and fluorescence imaging (FLI) possesses high potential for biological and medical applications. Herein we report the first design, synthesis, dual detection validation, and cytotoxic testing of four promising BODIPY dyes for dual (19) F MRI-fluorescence detection. Using straightforward Steglich reactions, small fluorinated alcohols were easily covalently tethered to a BODIPY dye in high yields, leaving its fluorescence properties unaffected. The synthesized compounds were analyzed with various techniques to demonstrate their potential utility in dual imaging. As expected, the chemically and magnetically equivalent trifluoromethyl groups of the agents exhibited a single NMR signal. The determined longitudinal relaxation times T1 and the transverse relaxation times T2 , both in the lower second range, enabled the imaging of four compounds in vitro. The most auspicious dual (19) F MRI-fluorescence agent was also successfully imaged in a mouse post-mortem within a 9.4 T small-animal tomograph. Toxicological assays with human cells (primary HUVEC and HepG2 cell line) also indicated the possibility for animal testing.

Methods to Increase the Metabolic Stability of (18)F-Radiotracers. Molecules 2015; 20:16186-220.

Abstract
The majority of pharmaceuticals and other organic compounds incorporating radiotracers that are considered foreign to the body undergo metabolic changes in vivo. Metabolic degradation of these drugs is commonly caused by a system of enzymes of low substrate specificity requirement, which is present mainly in the liver, but drug metabolism may also take place in the kidneys or other organs. Thus, radiotracers and all other pharmaceuticals are faced with enormous challenges to maintain their stability in vivo highlighting the importance of their structure. Often in practice, such biologically active molecules exhibit these properties in vitro, but fail during in vivo studies due to obtaining an increased metabolism within minutes. Many pharmacologically and biologically interesting compounds never see application due to their lack of stability. One of the most important issues of radiotracers development based on fluorine-18 is the stability in vitro and in vivo. Sometimes, the metabolism of 18F-radiotracers goes along with the cleavage of the C-F bond and with the rejection of [18F]fluoride mostly combined with high background and accumulation in the skeleton. This review deals with the impact of radiodefluorination and with approaches to stabilize the C-F bond to avoid the cleavage between fluorine and carbon.

Abstract
Fluorine-containing fluorochromes are important validation agents for positron emission tomography imaging compounds, as they can be readily validated in cells by fluorescence imaging. In particular, the (18) F-labeled BODIPY-FL fluorophore has emerged as an important platform, but little is known about alternative (18) F-labeling strategies or labeling on red-shifted fluorophores. In this study we explore acid-catalyzed (18) F/(19) F exchange on a range of commercially available N-hydroxysuccinimidyl ester and maleimide BODIPY fluorophores. We show this method to be a simple and efficient (18) F-labeling strategy for a diverse span of fluorescent compounds, including a BODIPY-modified PARP-1 inhibitor, and amine- and thiol-reactive BODIPY fluorophores.
