Wang, Xinhua published the artcileSynergistic photoredox and tertiary amine catalysis: generation of allylic sulfones from Morita-Baylis-Hillman acetates and sulfur dioxide, SDS of cas: 1205-17-0, the main research area is potassium alkyltrifluoroborate Morita Baylis Hillman acetate tertiary amine photocatalyst; Morita Baylis Hillman acetate Hantzsch ester tertiary amine photocatalyst; alkyl sulfonyl aryl methyl cycloalkenone preparation.

The first example of the synthesis of allylic sulfones through synergistic photoredox and tertiary amine catalysis, starting from MBH acetates, DABCO·(SO2)2 and 4-substituted Hantzsch esters or potassium alkyltrifluoroborates via a radical pathway was reported. A wide range of allylic sulfones was easily obtained in moderate to excellent yields. Mechanistic studies showed that synergistic photoredox and tertiary amine catalysis was essential for this successful transformation with the insertion of sulfur dioxide.

Rastogi, S. C. published the artcileFragrance chemicals in domestic and occupational products, Synthetic Route of 1205-17-0, the main research area is fragrance occupational product allergy.

Epidemiol. studies have described an increasing prevalence of fragrance allergy and indicated an association with hand eczema. Fifty-nine domestic and occupational products intended for hand exposure were subjected to gas chromatog.-mass spectrometric (GC-MS) analyses to test the hypothesis that fragrance chems. known to have the potential to cause contact allergy but not included in fragrance mix (FM) may be common ingredients in these products. A quant. anal. of 19 selected fragrances was performed by GC-MS. Further anal. of GC-MS data revealed the presence of 43 other fragrance chems./groups of fragrance chems. in the products investigated. Among the 19 target substances the most commonly detected were limonene in 78%, linalool in 61% and citronellol in 47% of the products investigated. The FM ingredients were present in these products with the following frequencies: oak moss (evernic acid Me ester) 2%, cinnamic alc. 2%, cinnamic aldehyde (cinnamal) 3%, isoeugenol 5%, α-amylcinnamic aldehyde (amyl cinnamal) 8%, hydroxycitronellal 12%, eugenol 27%, and geraniol 41%. Thus, the chem. analyses of domestic and occupational products indicates that investigation of potential contact allergy related to these products types should consider fragrance allergens addnl. to those in the FM, since these may occur with high frequency.

Hu, Wenbin published the artcileHeavy-atom-free charge transfer photosensitizers: Tuning the efficiency of BODIPY in singlet oxygen generation via intramolecular electron donor-acceptor interaction, Computed Properties of 86-51-1, the main research area is heavy atom charge transfer photosensitizer Boron dipyrromethenes; intramol electron donor acceptor.

To test the tunability of charge transfer (CT)-based BODIPY photosensitizers in generating singlet oxygen (1Δg), twelve meso-phenyl-BODIPY (donor-acceptor) type compounds have been synthesized and fully characterized, in which the Ph moiety is modified with resp. 0, 1, 2 and 3 methoxy groups to increase its electron-donating ability. The UV-Vis absorption spectra, fluorescence emission spectra, fluorescence quantum yield, fluorescence lifetime, excited triplet state formation, and singlet oxygen formation properties are measured. DFT quantum chem. computation is also carried out to explain the experiments The occurrence of intra-mol. CT is confirmed by UV-Vis absorption, fluorescence properties and quantum chem. computation. The triplet excited state formation is evidenced by laser radiation flash photolysis technique. The quant. photosensitized singlet oxygen formation is demonstrated by DPBF (diphenylisobenzofuran) chem. trapping method. This type of BODIPY CT photosensitizers show good tunability in generating singlet oxygen (1Δg). When the number of methoxy group on the donor is increased (so that CT is enhanced), the efficiency of singlet oxygen generation becomes higher from 0.070 to 0.30. When solvent polarity is increased (CT is also enhanced), the efficiency of singlet oxygen generation is also increased significantly. The increase in singlet oxygen generation is accompanied by the decrease in fluorescence quantum yield and fluorescence lifetime values. These facts show that a higher CT efficiency in a simple phenyl-BODIPY donor-acceptor conjugate can lead to significant higher quantum yield of singlet oxygen generation. These results are useful in designing novel CT-based heavy-atom-free photosensitizers for photodynamic therapy of tumor.

Sbaraglini, Maria L. published the artcileLipase catalyzed synthesis of alkyl phenylacetates with anticonvulsant activity, SDS of cas: 104-01-8, the main research area is alkyl phenylacetate preparation mol docking anticonvulsant; phenylacetic acid esterification lipase catalyst.

Despite the wide spectra of available antiepileptic drugs, one third of the patients still suffer from drug-resistant epilepsy, justifying the ongoing search of novel therapies. The anticonvulsant activity of Pr 4-hydroxybenzoate was previously identified through in silico screening. Here, Candida antarctica B (CAL B) lipase was employed as biocatalyst for the enzymic synthesis of a series of alkyl phenylacetates I (R = H, 4-OH, 4-MeO, 4-NH2, 4-NO2; R1 = Et, Pr) which, based on their mol. similarity to propylparaben, were tested in two acute mice models of seizure (maximal electroshock seizure and s.c. pentylenetetrazol tests). Mol. docking was later applied to explain the observed activities. All the synthesized compounds displayed some degree of protective activity in the maximal electroshock seizure model, whereas none of them showed protection against pentylenetetrazol-induced convulsions. Et 4-methoxyphenylacetate and Pr phenylacetate showed the most promising in vivo results. In consistence with the observed anticonvulsant effects, Pr phenylacetate obtained the best predicted binding energy among the synthesized alkyl phenylacetates.
