Me(CH₂)_nCOCO(CH₂)_mOR (I; n = 1,3; m = 6, 8, 10; R = CMe₃, H) were prepared from Me(CH₂)_nCH(OH)CN or N,N-diethyl-2-ethylenedioxyhexanoanide and Me₃CO(CH₂)_nMgBr. I were converted to Me(CH₂)_nCC(CH₂)_mOR(II) via their dihydrazone. II were converted to cis-Me(CH₂)_nCH:CH(CH₂)_mOAc (III) via P-2 nickel reduction and to trans–III via LiAlH₄ reduction

Dokmanovic, Milos published the artcileHistone Deacetylase Inhibitors: Overview and Perspectives, Product Details of C10H18O4, the publication is Molecular Cancer Research (2007), 5(10), 981-989, database is CAplus and MEDLINE.

A review. Histone deacetylase inhibitors (HDACi) comprise structurally diverse compounds that are a group of targeted anticancer agents. The first of these new HDACi, vorinostat (suberoylanilide hydroxamic acid), has received Food and Drug Administration approval for treating patients with cutaneous T-cell lymphoma. This review focuses on the activities of the 11 zinc-containing HDACs, their histone and nonhistone protein substrates, and the different pathways by which HDACi induce transformed cell death. A hypothesis is presented to explain the relative resistance of normal cells to HDACi-induced cell death.

Xu, Xiaoqing published the artcileSynthetic phenolic antioxidants: Metabolism, hazards and mechanism of action, SDS of cas: 121-79-9, the publication is Food Chemistry (2021), 129488, database is CAplus and MEDLINE.

A review. Synthetic phenolic antioxidants can interact with peroxides produced by food. This paper reviews correlation between BHA, BHT and TBHQ metabolism and harms they cause and provides a theor. basis for rational use of BHA, BHT and TBHQ in food, and also put some attention on the transformation and metabolic products of PG. We introduce BHA, BHT, TBHQ, PG and their possible metabolic pathways, and discuss possible harms and their specific mechanisms responsible. Excessive addition or incorrect use of synthetic phenolic antioxidants results in carcinogenicity, cytotoxicity, oxidative stress induction and endocrine disrupting effects, which warrant attention. BHA carcinogenicity is related to production of metabolites TBHQ and TQ, and cytotoxic effect of BHA is the main cause of apoptosis induction. BHT carcinogenicity depends on DNA damage degree, and tumor promotion is mainly related to production of quinone methylation metabolites. TBHQ carcinogenicity is related to induction of metabolite TQ and enzyme CYP1A1.

Species captured included representatives of the following families: Gracillariidae (3 species), Yponomeutidae (1), Oecophoridae (1), Elachistidae (1), Coleophoridae (1), Blastobasidae (1), Gelechiidae (4), Tortricidae (38), Pyralidae (1), Zygaenidae (2), Geometridae (1), Lymantriidae (2), Noctuidae (5). New sex attractants were found for some of the species recorded, e.g. Calybites aurogutella, Phyllonorycter mespilellus, Coleophora palliatella, Teleoides decorella, Oegoconia quadripuncta, Cydia gemmiferana, C. succedana, Eana derivana, Dichrorampha incursana, Spatalistis bifasciana, Zeiraphera isertana, Zygaena scabiosae. Chronic orchard pests such as Cydia pomonella, C. funebrana and Anarsia lineatella were abundant in pheromone traps located on uncultivated habitats. Catches of Apotomis infida, Cnephasia oxyacanthana, Cydia gemmiferana, Eana derivana and Pammene albugiana are remarkable, showing that pheromone traps can be used successfully as a complementary method in faunistics.

Xia, Yuanyuan published the artcilePreparation of cellulose beads with high homogeneity, low crystallinity, and tunable internal structure, SDS of cas: 121-79-9, the publication is Cellulose (Dordrecht, Netherlands) (2022), 29(3), 1473-1485, database is CAplus.

The preparation of cellulose beads has attracted much attention in the application of advanced green materials. Herein, the uniform and controllable cellulose beads were prepared by first dissolving the pulp into N-methylmorpholine N-oxide (NMMO), and then regenerated in various coagulation baths (water, alc., acid, NMMO, etc.). Results showed that the crystalline structure of regenerated cellulose changed from cellulose I to cellulose II. Besides, the cellulose beads regenerated in Methanol (MT-cellulose bead) had the highest porosity (90.51%) and crystallinity (62.59%). Laser confocal microscopy was employed to reveal the coagulation mechanism of cellulose beads, and the solidification process was carried out from the inside to the outside. This is a green and facile method for preparing cellulose beads with different structures and properties that can be widely used in absorbent materials, energy storage materials, and protein chromatog.

Benzyl N,N-diethyldithiocarbamate (BDC) was synthesized. The results showed the degree of replacement reaction increased with the advance of time and temperature in reaction. BDC as iniferter in the photopolymerization of styrene and Me methacrylate was investigated. The conversion of styrene or Me methacrylate increased with the increasing photopolymerizing time in nonlinear mode and ambient temperature The viscosity-viscosity average mol. weight of PMMA and polystyrene increased linearly with the conversion and the polymer had broad mol. weight distribution. The photopolymerization for preparing styrene-Me methacrylate block copolymer with BDC as iniferter was “living” radical polymerization
