Chen, Hong published the artcileInterpenetrating polymer network hydrogels using natural based dyes initiating systems: Antibacterial activity and 3D/4D performance, Recommanded Product: Ethyl 4-dimethylaminobenzoate, the publication is European Polymer Journal (2022), 111042, database is CAplus.

In the past few decades, interpenetrating polymer network (IPN) hydrogels have attracted huge attention due to their special cell-like structures, interpenetrating interface, and two-phase continuity, which has special synergistic effects on their performance and function. In this work, the best candidates were selected from the firstly synthesized 11 dyes based on 1-aryl-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one or 3-aryl-1-(3,4,5-trimethoxyphenyl)prop, and then combined with an amine (i.e., 1,4-(dimethylamino) Et benzoate, EDB) and an iodonium salts (bis(4-tert-butylphenyl)iodonium hexafluorophosphate, Iod) as a three-component visible light photoinitiating systems (PIS) to induce both free-radical photopolymerization (FRP) of poly(ethylene glycol) diacrylate (PEG-DA) and cationic photopolymerization (CP) of 3,4-epoxycyclohexylmethyl-3′,4′-epoxycyclohexanecarboxylate (EPOX) and in situ reduction of silver cations into silver nanoparticles to prepare interpenetrating network polymers (IPN) with antibacterial activity for Gram-pos. bacteria (e.g. Staphylococcus aureus) and Gram-neg. bacteria (e.g. Pseudomonas aeruginosa). More interestingly, stable 3D patterns were successfully produced through direct laser write (DLW) technique, and they exhibited reversible swelling properties and shape memory effects caused by swelling and dehydration processes, thus enabling 4D printing.

Sadagopan, K. published the artcileSynthesis and characterization of azo-based methacrylate polymers with methoxy and nitro end groups for nonlinear optical applications, Synthetic Route of 135529-02-1, the publication is Journal of Applied Polymer Science (2007), 104(6), 3497-3504, database is CAplus.

One new and three already described azo-based methacrylate monomers with methoxy and nitro end groups and spacer length 2 and 6 were synthesized. These monomers were copolymerized with Me methacrylate and the monomers and copolymers were characterized by classical spectroscopy techniques (FTIR, NMR, and UV-VIS), gel permeation chromatog. (GPC), elemental anal. and thermal anal. (TGA and DSC). The glass transition temperature of the polymers was above room temperature and thermal decomposition temperatures above 100°. All the polymers were amorphous in nature and formed excellent homogeneous films with good optical transparency. The polymer films coated on indium tin oxide glass slides were poled and their order parameters were calculated to check the stability of oriented dipoles. Few samples were also studied for their second harmonic generation properties. Temporal stability, checked up to 120 h at room temperature, was quite satisfactory.

Hu, Lijun published the artcileDesign, synthesis, and biological studies of novel 3-benzamidobenzoic acid derivatives as farnesoid X receptor partial agonist, HPLC of Formula: 1877-71-0, the publication is European Journal of Medicinal Chemistry (2021), 113106, database is CAplus and MEDLINE.

Farnesoid X receptor (FXR), a bile acid-activated nuclear receptor, regulates the metabolism of bile acid and lipids as well as maintains the stability of internal environment. FXR was considered as a therapeutic target of liver disorders, such as drug-induced liver injury, fatty liver and cholestasis. The previous reported FXR partial agonist I was a suitable lead compound in terms of its high potent and low mol. size, while the docking study of compound I suggested a large unoccupied hydrophobic pocket, which might be provided more possibility of structure-activity relationship (SAR) study. In this study, we have performed comprehensive SAR and mol. modeling studies based on lead compound I. All of these efforts resulted in the identification of a novel series of FXR partial agonists. In this series, compound II revealed the best activity and strong interaction with binding pocket of FXR. Moreover, compound II protected mice against acetaminophen-induced hepatotoxicity by the regulation of FXR-related gene expression and improving antioxidant capacity. In summary, these results suggest that compound II is a promising FXR partial agonist suitable for further investigation.

Ronson, Thomas O. published the artcileRuthenium-Catalyzed Reductive Arylation of N-(2-Pyridinyl)amides with Isopropanol and Arylboronate Esters, Synthetic Route of 1877-71-0, the publication is Angewandte Chemie, International Edition (2019), 58(2), 482-487, database is CAplus and MEDLINE.

A new three-component reductive arylation of amides with stable reactants (iPrOH and arylboronate esters), making use of a 2-pyridinyl (Py) directing group, is described. The N-Py-amide substrates are readily prepared from carboxylic acids and PyNH₂, and the resulting N-Py-1-arylalkanamine reaction products are easily transformed into the corresponding chlorides by substitution of the HN-Py group with HCl. The 1-aryl-1-chloroalkane products allow substitution and cross-coupling reactions. Therefore, a general protocol for the transformation of carboxylic acids into a variety of functionalities is obtained. The Py-NH₂ byproduct can be recycled.

Kasukabe, T. published the artcileAn anticancer derivative of butyric acid (pivalyloxymethyl butyrate) and daunorubicin cooperatively prolong survival of mice inoculated with monocytic leukemia cells, Synthetic Route of 122110-53-6, the publication is British Journal of Cancer (1997), 75(6), 850-854, database is CAplus and MEDLINE.

Pivalyloxymethyl butyrate (AN-9) inhibited the proliferation of and induced apoptosis in mouse monocytic leukemia Mm-A cells; Na butyrate, but not AN-9, induced differentiation of the cells. AN-9 and various DNA-specific antineoplastic agents synergistically inhibited the growth of Mm-A cells, and simultaneous treatment was required to evoke the maximum growth-inhibitory effect. On the other hand, there was no synergy between butyrate and these drugs, or between AN-9 and several antimetabolic agents, in inhibiting the growth of the cells, suggesting that the synergistic effect is specific to AN-9 and DNA-reacting agents. AN-9, given alone, dose-dependently prolonged the survival of mice inoculated with Mm-A cells. Moreover, administration of AN-9 plus daunorubicin (DNR) further prolonged survival.

Aviram, Adina published the artcileEffect of the cytostatic butyric acid pro-drug, pivaloyloxymethyl butyrate, on the tumorigenicity of cancer cells, Recommanded Product: (Pivaloyloxy)methyl butyrate, the publication is Journal of Cancer Research and Clinical Oncology (1997), 123(5), 267-271, database is CAplus and MEDLINE.

Pivaloyloxymethyl butyrate (AN-9) was demonstrated to be a cytostatic but not cytotoxic agent in a myelomonocytic cell line (WEHI). The expression of the early regulatory genes, c-myc and c-jun were changed. Although these events occurred already after 1 h of exposure to AN-9, the tumorigenicity of these reduced only after 4 h of exposure. Tumorigenicity of the highly metastatic subclone of Lewis lung carcinoma was almost diminished after 1h of exposure. In both cell types a 10-fold higher concentration of BA did not affect the tumorigenicity of the cells as did AN-9.

Xu, Yan-Li published the artcileHighly enantioselective one-pot sequential synthesis of valerolactones and pyrazolones bearing all-carbon quaternary stereocentres, Quality Control of 517-23-7, the publication is Organic & Biomolecular Chemistry (2021), 19(7), 1610-1615, database is CAplus and MEDLINE.

Highly enantiopure and bioactive δ-valerolactones I (R = Me, Ph, 1-naphthyl, 2-chlorophenyl, etc.; R¹ = Ph, 1-naphthyl, 2-methylphenyl, etc.; n = 0, 1), and pyrazolones II, bearing α-all-carbon quaternary stereocentres, were successfully and sequentially prepared via a one-pot procedure starting from readily available, inexpensive materials, catalyzed by a new chiral squaramide III under mild reaction conditions. An organocatalytic Michael reaction afforded the valerolactones I, while a one-pot Michael-hydrazinolysis-imidization cascade yielded the pyrazolones II. This procedure is economically efficient and environmentally benign.
