The porphyrins were fully characterized using a combination of NMR spectroscopy, high-resolution mass spectrometry, and UV-Vis absorption and emission spectroscopies. Two of the free-base porphyrins were heated in the presence of AIBN or benzoyl peroxide as the initiator. The major isolated products of these reactions contained two porphyrin units based on the results of MALDI-MS and 1H NMR analysis data, which was supported by the results of FTIR, UV-Vis absorption and emission spectroscopies, and gel permeation and liquid chromatographies. Additionally, the acrylamide-functionalized porphyrin could be attached to a polylysine scaffold under basic conditions. These results suggest that the olefinic handle can be used to assemble structures containing multiple porphyrinic macrocycles.","PeriodicalId":16876,"journal":{"name":"Journal of Porphyrins and Phthalocyanines","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46331218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used DFT calculations to study how this low-lying region of the spectrum of the NCP-2H isomer is affected by the introduction of transition metals with various ([Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] d-electron configurations. The spin ground state of these complexes is mostly dependent on the number of unpaired electrons, both with and without the presence of an axial ligand. The analysis of the electronic distribution and spin density showed that these unpaired electrons are often harbored by the N-confused porphyrin ring instead of on the metal. Time-dependent DFT results indicated that the aromatic system of porphyrin is disrupted in the N-confused isomer: instead of the typical large Soret band, this now gives rise to two peaks of much lower intensity. Most metallo-porphyrins exhibited similar optical properties, with the HOMO/LUMO orbitals showing a mixed metal/porphyrin character. The only exception was the Rh metalloporphyrin that exhibited a ligand-to-metal charge transfer band with increasing intensity as function of the ligand field. This suggests Rh is the only metal whose orbitals are higher in energy than the ligand’s, indicating that it is the only system where the redox processes occur on the metal.","PeriodicalId":16876,"journal":{"name":"Journal of Porphyrins and Phthalocyanines","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44059580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional antimicrobials have thus weakened in their effectiveness against microbes, calling for the development of innovative strategies to combat the emerging global health crisis. A promising therapy for filling this gap is photodynamic antimicrobial chemotherapy which destroys microorganisms by making use of the combined action of a photosensitizer, light, and oxygen. The modality inactivates a wide range of pathogens, including bacteria, fungi, protozoa, and viruses. Of greater interest in photodynamic antimicrobial chemotherapy is the ability to destroy resistant strains of microbes without encouraging selection for resistance genes, thus immensely contributing to the fight against antimicrobial resistance. Different PSs vary in their microbial inactivation efficacies. Therefore, various structural modification approaches are being adopted to improve their respective activities. In this paper, recent studies focusing on strategies employed to improve the effectiveness and efficacies of PSs used in photodynamic antimicrobial chemotherapy are reviewed.","PeriodicalId":16876,"journal":{"name":"Journal of Porphyrins and Phthalocyanines","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41578506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, proteins interacting with cyanine dyes have not been investigated clearly. Here, we report a chemical proteomics approach for the identification of mitochondrial proteins associated with cyanine dyes. This approach uses affinity-based photocrosslinking of Cy5-diazirine-alkyne (Cy5-DAyne) in combination with selective enrichment of target proteins by bio-orthogonal supramolecular latching based on unique host-guest interaction between cucurbit[7]uril (CB[7]) and its selected guest such as adamantylammonium (AdA). The enriched proteins then were analyzed using LC–MS/MS to provide a list of proteins closely associated with the Cy5 motif. This study suggests that the proteomic environment around the Cy5 motif is highly associated with energy production processes, including the respiratory chain, ATP synthesis, and fatty acid oxidization. Moreover, it demonstrates the potential of this chemical proteomic approach for the investigation of other organellar proteins using different selective dyes.","PeriodicalId":16876,"journal":{"name":"Journal of Porphyrins and Phthalocyanines","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42798152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
