Homo- and hetero-[3]rotaxanes with two π-systems clasped in a single macrocycle
Klotz, Eric J. F.,Claridge, Tim D. W.,Anderson, Harry L.
, p. 15374 - 15375 (2006)
Here we present the first synthesis of a [3]rotaxane with two dumbbell components threaded through a single γ-cyclodextrin macrocycle. This synthesis is carried out in two steps: first one dumbbell is synthesized threaded through the macrocycle to give a

Fluorogenic probes can be used to minimize the background fluorescence of unreacted and nonspecifically adsorbed reagents. The preceding years have brought substantial developments in the design and synthesis of bioorthogonally applicable fluorogenic syst
Smart J-aggregate of cyanine photosensitizer with the ability to target tumor and enhance photodynamic therapy efficacy
Li, Miao,Sun, Wen,Tian, Ruisong,Cao, Jianfang,Tian, Ye,Gurram, Bhaskar,Fan, Jiangli,Peng, Xiaojun
, (2021)
Photodynamic therapy (PDT) has been demonstrated to be effective for cancer treatment. Design of photosensitizers (PS) featuring tumor targeting, long excitation wavelengths, and high singlet oxygen quantum yields (Φ(1O2)) is the cru

The bis(vinyl ruthenium)-modified squaraine dye 1 was synthesized by treatment of [RuHCl(CO)(PiPr3)2] with bis(ethynyl)- substituted squaraine 8. Spectroscopic and electrochemical measurements on 1 and its organic precursors 6-8 were
Hypoxia-activated NIR photosensitizer anchoring in the mitochondria for photodynamic therapy
Xu, Feng,Li, Haidong,Yao, Qichao,Ge, Haoying,Fan, Jiangli,Sun, Wen,Wang, Jingyun,Peng, Xiaojun
, p. 10586 - 10594 (2019)
Photodynamic therapy is considered as a promising treatment for cancer, but still faces several challenges. The hypoxic environment in solid tumors, imprecise tumor recognition and the lack of selectivity between normal and cancer cells extremely hinder t
Iodinated xanthene-cyanine NIR dyes as potential photosensitizers for antimicrobial photodynamic therapy
Ebaston, T. M.,Gellerman, Gary,Nakonechny, Faina,Patsenker, Leonid,Talalai, Efrosiniia

Photosensitizers (PSs) are chemical entities that upon light exposure are able to produce cytotoxic species such as singlet oxygen superoxide and free radicals. PSs are used in photodynamic therapy applications (PDT) to eradicate cancer cells, pathogenic bacteria, fungi, and viruses. Development of the NIR-activatable photosensitizes with high phototoxicity and low toxicity in dark conditions is challenging. Here we first report on the synthesis and antimicrobial testing of the new NIR photosensitizers based on the iodinated xanthene-cyanine dyes. These new photosensitizers exhibit high antimicrobial efficacy on Staphylococcus aureus pathogens at low dye concentration (~0.5 μM) and low NIR light dose (24.3 J/cm2).

Photodynamic therapy (PDT) represents an effective treatment to cure cancer. The targeting ability of the photosensitizer is of utmost importance. Photosensitizers that discriminate cancer cells can avoid the killing of normal cells and improve PDT effica
Bioorthogonally Applicable Fluorogenic Cyanine-Tetrazines for No-Wash Super-Resolution Imaging
Knorr, Gergely,Kozma, Eszter,Schaart, Judith M.,Németh, Krisztina,T?r?k, Gy?rgy,Kele, Péter

The synthesis, fluorogenic characterization, and labeling application of four tetrazine-quenched cyanine probes with emission maxima in the red-far red range is reported. Fluorescence of the cyanine-cores is quenched via through-bond-energy-transfer (TBET) exerted by a bioorthogonal tetrazine unit. Upon bioorthogonal labeling reaction with cyclooctyne tagged proteins, the quenching effect ceases, and thus the fluorescence reinstates, resulting in an increase in fluorescence intensity. As a rare example among indocyanines, one of our new probes was found suitable in STED-based super-resolution imaging. The applicability of this fluorogenic Tet-Cy3 probe was therefore further demonstrated in the bioorthogonal labeling of cytoskeletal protein, actin, with subsequent super-resolution microscopy (STED) imaging even under no-wash conditions.
