Fluorescent polarity probes for identifying bovine serum albumin: Amplification effect of para-substituted benzene

Fluorescent probes 1-3 with coumarin as the fluorophore were designed and synthesized for the determination of bovine serum albumin (BSA). All three probes exhibited evidently solvatochromic UV-vis and fluorescence spectra. Compound 3 was the most effective towards the solvent's polarity: 155 nm (vs. 60 nm for 1 and 100 nm for 2) red shift in the emission maximum was found as the solvent changing from cyclohexane to phosphate buffer solution. These compounds were applied to detect BSA based on the hypothesis that the polarity of the microenvironment surrounding the probe will undergo significant change when the probe moves from the bulk solution to the hydrophobic domains of BSA. 3 was the most sensitive towards BSA and the detection limit of BSA was 0.6 μg/mL with 3 as the probe, which ensured the detection of BSA content in fetal bovine serum with good recovery.

Some thiazole derivatives bearing dithiocarbamic acid esters were synthesized in order to investigate their anticandidal activity and cytotoxicity. The structures of the obtained final compounds (6a-j) were confirmed by spectral data (IR, 1H NMR, 13C NMR, and MS) and elemental analysis. The anticandidal activity of the compounds was determined (6a-j) using the microbroth dilution method and their cytotoxicity was evaluated according to the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay against normal cells. Contrary to expectations, weak antifungal activity was observed with IC50values ranging between 30 and 403 μg/mL.

Under superacid conditions, aromatic amines are directly and regioselectively 1,1-difluoroethylated. Low temperature in situ NMR studies confirmed the presence of benzylic α-fluoronium and α-chloronium ions as key intermediates in the reaction. This method has a wide substrate scope and can be applied to the late-stage functionalization of natural alkaloids and active pharmaceutical ingredients.
Chlorination Reaction of Aromatic Compounds and Unsaturated Carbon-Carbon Bonds with Chlorine on Demand
Liu, Feng,Wu, Na,Cheng, Xu
supporting information, p. 3015 - 3020 (2021/05/05)
Chlorination with chlorine is straightforward, highly reactive, and versatile, but it has significant limitations. In this Letter, we introduce a protocol that could combine the efficiency of electrochemical transformation and the high reactivity of chlorine. By utilizing Cl3CCN as the chloride source, donating up to all three chloride atom, the reaction could generate and consume the chlorine in situ on demand to achieve the chlorination of aromatic compounds and electrodeficient alkenes.
