The development of stimuli-responsive difluoroboron β-diketonate materials has attracted more and more attention for their potential application in optoelectronics and functional bio-materials. In this study, we have designed and synthesized a novel photoresponsive dithienylethene-containing difluoroboron β-diketonate complex 1 by Knoevenagel condensation reaction. Its structure have been confirmed by ¹H NMR, ¹³C NMR and HRMS (ESI). And it exhibited solvent-dependent photophys. properties in solution before visible light irradiation Subsequently, photochromism of 1 was investigated in solution, and it was found that 1 revealed solvent-dependent and visible light-triggered NIR photochromic behaviors. Moreover, it also displayed excellent fluorescence switching behavior and photochromism in the film state upon visible light irradiation Accordingly, the dithienylethene 1 may be acted as a novel visible light-responsive fluorescence dyes in optoelectronic materials.

The reagents 6-coumarinsulfonyl-β-cyclodextrin (6-Cs-β-CD) with mol. recognition function were synthesized and identified. Both basic condition and enough illumination were necessary for obtaining stable and strong fluorescence. By using 6-Cs-β-CD as the host, cyclohexanol, cyclohexene, cyclohexane, or bromocyclohexane as the guest, the recognition properties were studied. The affinity of 6-Cs-β-CD and the guest is distinct with different hydrophobicity of the guest.

Yang, Shizhong published the artcilePreliminary study on 6-coumarinsulfonyl chloride as luminescence labeling reagent, Application of Coumarin-6-sulfonyl chloride, the publication is Fenxi Ceshi Xuebao (1993), 12(3), 49-52, database is CAplus.

Excessive 6-coumarinsulfonyl chloride (C6SCL) is reacted with L-alanine in pH 9.11 buffer solution (H₃BO₃-NaOH) at 40°C for 40 min and the reaction mixture is extracted with Et acetate. When the extract is dropped on a polyamide membrane and developed with formic acid-water (1 + 1) solution, the alanine C6SCL derivative is separated The R_f value is 0.67, 0.47 and 0.50 for the derivative, C6SCL and C6SOH, resp. After spraying the spot of derivative with 1 mol L^-1 NaOH solution and pre-illuminating and drying under UV light for 10 min, fluorescence intensity of the spot has a good linear relationship with amount of alanine in the range of (4-60) × 10^-11 mol. In addition, more intensive room temperature phosphorescence (RTP) of the derivation is induced by using 1.0 mol/L Pb(OAc)₂ as the heavy atom perturber and filter paper as solid substrate. All results show that the C₆SCL can be expected to serve as not only a fluorescence labeling reagent, but also a RTP one for amino acid etc.

An expansive data set containing 33 substrates, 36 unique monophosphine ligands, and two solvents was produced for the NiCl₂·6H₂O catalyzed aryl (pseudo)halide borylation with tetrahydroxydiboron for a total of 1632 reactions. Exploratory data anal. revealed excellent reaction performance with simple triarylphosphines (P(p-F-Ph)₃ and P(p-Anis)₃) and mixed aryl-alkyl phosphines (PPh₂Cy), in addition to the previously established high performance with Cy-JohnPhos. The data were used to train machine learning models that predicted out of sample reaction performance with a root-mean-square error of 18.4. The important features extracted from the models identified three phosphine parameters that offered reliable reactivity thresholds for identifying optimal ligand performance. The predictive models showed reasonable performance for predicting reaction yields employing ligands not included in model training, while the important feature boundaries accurately classified the performance of 10 of the 12 external ligands examined

Zhou, Yan published the artcileDesign, synthesis, and evaluation of dihydropyranopyrazole derivatives as novel PDE2 inhibitors for the treatment of Alzheimer’s disease, HPLC of Formula: 939-99-1, the publication is Molecules (2021), 26(10), 3034, database is CAplus and MEDLINE.

In this study, (R)-LZ77 was obtained as a hit compound with moderate PDE2 inhibitory activity (IC₅₀ = 261.3 nM) using a high-throughput virtual screening method based on mol. dynamics. Then, 28 dihydropyranopyrazole derivatives I [R¹ = H, CH₃O, Cl; R² = H, CH₃, CH₃O, etc.; R³ = H, CH₃, C₆H₅; R⁴ = H, CH₃O, Cl, etc; R⁵ = NH₂, (CH₃)₂N; n = 1, 2, 3] and II [R⁶ = Cl, CF₃; n = 0, 2, 3] were designed and synthesized as PDE2 inhibitors. Among them, compound (+)-I [R¹ = H; R² = CH₃O; R³ = CH₃; R⁴ = CF₃; R⁵ = NH₂; n = 1] was the most potent PDE2 inhibitor, with an IC₅₀ value of 41.5 nM. The mol. docking of PDE2-(+)-I [R¹ = H; R² = CH₃O; R³ = CH₃; R⁴ = CF₃; R⁵ = NH₂; n = 1] revealed that the 4-(trifluoromethyl)benzyloxyl side chain of the compound enters the H-pocket and forms strong hydrophobic interactions with L770/L809/F862, which improves inhibitory activity. The above results may provide insight for further structural optimization of highly potent PDE2 inhibitors and may lay the foundation for their use in the treatment of AD.
