Synthesis of fluorinated fluoresceins

Several novel fluorinated fluoresceins (Oregon Green dyes) were prepared by the reaction of fluororesorcinols with phthalic anhydride and its derivatives. A novel regiospecific synthesis of fluororesorcinols was key to the successful synthesis of these new fluorophores. (Polyfluoro)- nitrobenzenes were reacted with 2 equiv of sodium methoxide followed by reduction, hydrodediazoniation, and demethylation, giving the first straightforward synthesis of 2-fluororesorcinol, 4-fluororesorcinol, 2,4- difluororesorcinol, and 2,4,5-trifluororesorcinol. These fluorinated fluoresceins have higher photostability and ionize at a lower pH (pK(a) = 3.3-6.1) than fluorescein (pK(a) = 6.5). Some of the fluorinated fluoresceins have very high quantum yields (0.85-0.97), which, in combination with their lower pK(a)s and high photostability, makes them superior fluorescent dyes for use as reporter molecules in biological systems.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Safety of Tetrafluorophthalic anhydride, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 652-12-0, in my other articles.

Investigation of synthesis, characterization, photophysical and biological properties of novel antimicrobial fluorescent naphthalimide derivatives

A series of 4-amino-N-substituted-1,8-naphthalimide and 4-allylamino-N-substituted-1,8-naphthalimide derivatives were synthesized from intermediate 4-nitro-1,8-naphthalimide by imidation, reduction and allylation reactions. These compounds were characterized by thin layer chromatography (TLC), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), elemental analysis, 1H-nuclear magnetic resonance (1HNMR), 13C-NMR, liquid chromatography-mass spectroscopy, UV- Vis spectroscopy and fluorimetry. 1,8-Naphthalimide derivatives with amino and allylamino groups in the C-4 position exhibit fluorescent emission on irradiation. In addition, synthesized compounds had biological properties due to the presence of sulfonamide group (-SO2-N-) in their structure. The absorption maximum wavelength of synthesized dyes that are fluorescent is in the range of 427-439 nm while emitting in the range of 526-528.5 nm. The absorption spectra of synthesized dyes demonstrated that the type of substitutions in C-4 position and N-imide of naphthalimide ring had small effect on their colour. The photophysical characteristics of these dyes were assessed, and their Stokes shift values were determined in dimethylformamide solvent. The results demonstrated that Stokes shift values were between 3860 and 4469 cm- 1. Antibacterial and antifungal activities of the dyes were evaluated against gram positive and gram negative bacteria and Candida albicans fungi using cup plate, minimum inhibitory concentration and minimum bactericidal concentration methods. The results revealed that dye 10 had the most levels of antimicrobial activity against bacteria and fungi.

Highly Selective Red-Emitting Fluorescent Probe for Imaging Cancer Cells in Situ by Targeting Pim-1 Kinase

Based on the fact that enzyme-targeting probes are highly sensitive and selective, a novel red-emitting probe (NB-BF) for Pim-1 kinase including three parts, fluorophore (NB), linker, and inhibitor (BF), has been designed for cancer optical imaging. In its free state, NB-BF is folded and the fluorescence quenched by PET between fluorophore and inhibitor both in PBS buffer and in normal cells. Significantly, it emitted strong red fluorescence in Pim-1 overexpressed cancer cells. The specificity of NB-BF for Pim-1 kinase was directly demonstrated by gene silencing analysis. Furthermore, it is the first time to know where Pim-1 kinase mainly distributes at mitochondria with Pearson’s correlation factor (Rr) of 0.965 and to provide a fluorescent tool to verify the function of the Pim-1 kinase. More importantly, NB-BF was applied in tissue imaging and preferentially labeled tumors in vivo.
