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.

Paragraph 0035-0047, (2021/05/19)
The invention discloses a preparation method of an acetamide compound, the preparation method comprises the following steps: reacting tetracarbonyl dichloride rhodium, 1, 3-bis (diphenylphosphine) propane, tungsten carbonyl, sodium phosphate, sodium iodide, water, a nitro compound and dimethyl carbonate at 120 DEG C for 24 hours, and after the reaction is completed, performing post-treatment to obtain the acetamide compound. According to the preparation method, dimethyl carbonate serves as a C1 source and also serves as a green solvent, operation is easy, reaction starting raw materials are low in price and easy to obtain, the tolerance range of substrate functional groups is wide, and reaction efficiency is high. Various acetamide compounds can be synthesized according to actual needs, so that the practicability of the method is widened while the operation is convenient.

supporting information, (2021/12/22)
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.
