The interaction between the hemicyanine indole derivative H and the cucubit[n]urils Q[7] and Q[8] has been studied using 1H NMR and UV spectroscopy as well as by fluorescence experiments. Competitive studies on the inclusion of H by Q[7] and Q[

Sulfur dioxide (SO2) is considered as the fourth gas signal molecule after nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S). It plays important roles in several physiological processes. Therefore, the design and syn

Five derivatives of 2, 3, 3-trimethyl-3H-indolium containing different electron donor groups (H1 - H5) were synthesized for the determination of proteins. H3, a sensitive red-emitting fluorescent probe, was found for the discrimination of hydrophobic prot

A new mitochondria-targeted fluorescent probe HCy-D, constructed by dansyl and hemicyanine fluorophores, for SO2 derivatives (HSO3-/SO32-) was presented. This probe was designed based on a new FRET platform. HCy-D showed a ratiometric, sensitive and rapid response to HSO3-/SO32-. Importantly, HCy-D was successfully used for fluorescence imaging of endogenous bisulfite in HepG2 cells, which may benefit cancer diagnosis by discriminating liver cancer cells from normal liver cells.

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.

Novel bis-styryl dyes based on a quaternized centrosymmetrical benzodipyrrolenine moiety were synthesized by reaction of a quaternized benzodipyrrolenine with two equivalents of 4-dimethylaminobenzaldehyde, 4-dimethylaminocinnamoic aldehyde or 4-(3,5-diph
