Cyanines which selectively bind to G-quadruplex DNA complexes, particularly quadruplexes expressed in cancer cells, and methods of making and using thereof are described herein. The cyanine can be a symmetrical or unsymmetrical streptocyanine, hemicyanine, closed chain cyanine, or combinations thereof. The cyanine is preferably substituted with one or more groups that minimize or prevent aggregation of the cyanine and/or inhibit binding of the cyanine to duplex DNA. One or more of the cyanines can be formulated with one or more pharmaceutical excipients and/or carrier to prepare pharmaceutical compositions suitable for administration to a patient, particular a human patient. The compounds and compositions described herein can be used to treat diseases or disorders characterized by the expression of G-quadruplex DNA, such as cancer.

Peroxynitrite (ONOO?) is an important kind of reactive oxygen species (ROS), played an essential role in physiology and pathology. To date, various fluorescent probes for ONOO? have been constructed successfully, but these probes exhibit turn-on fluorescence signal in single channel. While, ratiometric fluorescent probes, especially those probes with large emission shift, are suitable for bioimage in two channels. Herein, a hemicyanine-based fluorescent probe named Cy-NH2 was designed and synthesized for ratiometric detection of ONOO?. The characteristics of Cy-NH2 are as follows: (1) The probe possesses a simple structure, which can be obtained by easy synthetic steps; (2) The ratiometric fluorescent probe owns large emission shift (248 nm) due to the disruption of pi-conjugation system caused by strong oxidizing ability of ONOO?; (3) The probe exhibits high sensitivity to ONOO? with 1728-fold enhancement of fluorescence intensity ratio and superior selectivity for ONOO? over various potentially interfering biological analytes; (4) The ratiometric fluorescent probe is applied for the image detection of exogenous and endogenous ONOO? in living cells successfully.

Synthesis of photo-switchable, Zn2+ sensitive hybrid materials was achieved by facile non-covalent functionalization of graphene, graphene oxide and carbon nanotubes with a pyrene-appended spiropyran. Solution phase binding studies, using UV-visible and fluorescence spectroscopy, indicated that the pyrene-spiropyran dyad was highly selective for Zn2+ over a range of potentially competitive cations and that binding occurred with 1:1 stoichiometry and a binding constant of K=1.4×104 mol-1 dm3 at 295 K. Zn2+ binding was promoted by UV irradiation or in darkness and reversed upon irradiation with visible light.

Novel, squarylium dyes containing 1-(alkylcarbamoylmethyl)-2,3,3-trimethyl- 3H-indolium groups were synthesized and their UV/Vis and fluorescence spectra, aggregation, photo-stability and association with bovine serum albumin were studied. The absorption and emission max wavelengths of the dyes in different solvents were in the range 619-653 nm. Compared to a typical ethyl squarylium dye, the introduction of alkylcarbamoylmethyl groups reduced aggregation and improved molar extinction coefficient, fluorescence quantum yield and photo-stability in water. Moreover, the fluorescence intensity of the dyes increased upon the addition of BSA in pH 7.0 phosphate buffer solution. An excellent linear relationship (r2 = 0.9982) was obtained between fluorescence intensity and bovine serum albumin concentration.

We evaluated 2-styrylindolium derivatives (6-11) as novel and selective probes for neurofibrillary tangles (NFTs) on brain sections of AD patients. The staining experiments indicated that these compounds may bind selectively to NFTs in the presence of ss-amyloid (Ass) plaques. Cell free binding assays confirmed that 2-[2-[4-(1-pyrrolidinyl)phenyl]ethenyl]-1,3,3-trimethyl-3H- indolium iodide (9) and 2-[2-[4-(diethylamino)phenyl]ethenyl]-1-butyl-3,3- dimethyl-3H-indolium iodide (11) display excellent affinities to Tau-aggregates (IC50 values of 5.1 and 1.4 nM, respectively) in the displacement of Thiazin Red R. These probes have good solubility in distilled water and low or no cytotoxicity in zebrafish embryo and liver hepatocellular carcinoma cell assays.
