Zhang, Xinyu published the artcileFluorocyclization of Allyl Alcohols and Amines to Access 3-Functionalized Oxetanes and Azetidines, Safety of 4-Chloro-3-(trifluoromethyl)benzenesulfonyl Chloride, the publication is Organic Letters (2021), 23(9), 3674-3679, database is CAplus and MEDLINE.

An efficient method to prepare 3-functionalized oxetanes and azetidines I [R¹ = H, Me, Ph, etc.; R² = Me, Ph, 2-FC₆H₄, etc.; R¹R² = (CH₂)₄, (CH₂)₅, (CH₂)₂O(CH₂)₂, etc.; X = O, NC(O)Ph, NSO₂Ph, etc.] was realized by fluorocyclization of readily available 2-azidoallyl alcs. and amines. Notably, this was the first example applying the fluorocyclization strategy to construct four-membered heterocycles. The pendant electron-donating group (-N₃ or -OR) played a crucial role in polarizing the C=C double bond and facilitating the cyclization process, as verified by DFT and exptl. studies.

Liu, Haitao published the artcileOptimization of clofibrate with O-desmethyl anetholtrithione lead to a novel hypolipidemia compound with hepatoprotective effect, Formula: C12H15ClO3, the publication is Bioorganic & Medicinal Chemistry Letters (2022), 128844, database is CAplus and MEDLINE.

Oxidative stress and inflammation were considered to be the major mechanisms in liver damage caused by clofibrate (CF). In order to obtain lipid-lowering drugs with less liver damage, the structure of clofibrate was optimized by O-desmethyl anetholtrithione and got the target compound clofibrate-O-desmethyl anetholtrithione (CF-ATT). CF-ATT significantly reduced the levels of plasma triglycerides (TG), total cholesterol (TC) in hyperlipidemia mice induced by Triton WR-1339. In addition, CF-ATT has a significantly protective effect on the liver compared with CF. The liver weight and liver coefficient were reduced. The hepatic function indexes were also decreased, such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alk. phosphatase (ALP). Histopathol. examination of the liver revealed that inflammatory cell infiltration, nuclear degeneration, cytoplasmic loosening and hepatocyte necrosis were ameliorated by administration with CF-ATT. The hepatoprotective mechanism showed that CF-ATT significantly up-regulated Nrf2 and HO-1 protein expression and down-regulated p-NF-κB P65 expression in the liver. CF-ATT has obviously antioxidant and anti-inflammatory activity. These findings suggested that CF-ATT has significant hypolipidemia activity and exact hepatoprotective effect possibly through the Nrf2/NF-κB-mediated signal pathway.

Zeng, Fang published the artcileCu²⁺ ion crosslinked carboxymethylcellulose/diatomite composite beads as an efficient catalyst for CuAAC reactions, Product Details of C7H6Cl2, the publication is Polymers for Advanced Technologies (2021), 32(9), 3609-3620, database is CAplus.

Cu²⁺-crosslinked CM-cellulose/diatomite composite beads (CuII@CMC/DE) were prepared in simple and efficient way using ionic crosslinking techniques. In CuII@CMC/DE beads, diatomite serves as a reinforcing filler, and divalent copper cation acts as crosslinking agent. The chem. structure and morphol. of as-fabricated CuII@CMC/DE beads were well characterized using various techniques such as ICP, FT-IR, XRD, SEM, EDS, elemental mapping, TEM, XPS, and TGA. The CuII@CMC/DE beads exerted superior catalytic performance in CuAAC reactions of benzyl halides, sodium azide, and alkynes to yield regioselective 1,4-disubstituted-1,2,3-triazoles in excellent yields under green conditions. In these resultant catalytic composite beads, Cu²⁺ was used not only as a crosslinking agent but also as a metal catalyst for CuAAC reaction. The composite beads can be easily separated by filter and reused at least four times without any significant decrease on its activity and selectivity.

Wei, Yanchen published the artcileDeep eutectic solvent-induced high-entropy structures in boron nitride for boosted initiation of aerobic oxidative desulfurization of diesel, Safety of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Applied Surface Science (2020), 146980, database is CAplus.

Depending on the synthetic method, the heteroatom-doped hexagonal B nitride (h-BN) catalysts can have different configurational entropies possessing various at. short-range orderings or phase separations, leading to complex grain boundaries for catalytic reactions. Herein, several C and O co-doped h-BN (BCNO) catalysts with different at. orderings were synthesized from the ternary deep eutectic solvents (DES). The exptl. results indicated the low steric resistance DES induced high-entropy structures (HES) in the BCNO, which involved a high d. of grain boundaries. The HES was studied as a catalytic booster for the radical initiation of aerobic oxidative desulfurization (ODS) of diesel. As a result, the optimized BCNO catalyzed ODS process owned the shortest induction period, rendering the complete aerobic oxidation of refractory S compounds in 6 h.

Sapogenin is the main block of Camellia oleifera saponin, which was purified and structurally modified by the C₂₈ acylation reaction to synthesize 19 new derivatives The growth and biofilm inhibition of Staphylococcus aureus and Escherichia coli was measured to evaluate their antibacterial effects. A three-dimensional quant. structure-activity relationship (3D-QSAR) assay indicated that the antibacterial activities were significantly enhanced after sapogenin was modified with an aromatic ring or heterocyclic ring and electron-withdrawing substituents at the meta or para position. Among them, the derivative of sapogenin with a 2-mercapto-4-methyl-5-thiazolyl acetyl group obviously destroyed bacterial biofilm and made bacteria lysis. 3D-QSAR provides practical information for the structural design of sapogenin derivatives with strong antibacterial activity, and the C. oleifera sapogenin derivative 28-O-(2-mercapto-4-methyl-5-thiazolyl)-3β,16α,21β,22α-O-tetrahydroxy-oleantel-2-ene-23-aldehyde (S-16) is an effective candidate as an antibacterial agent for the prevention of bacterial resistance against antibiotics.

Wang, Wentian published the artcileDesign and Synthesis of TASIN Analogues Specifically Targeting Colorectal Cancer Cell Lines with Mutant Adenomatous Polyposis Coli (APC), Related Products of chlorides-buliding-blocks, the publication is Journal of Medicinal Chemistry (2019), 62(10), 5217-5241, database is CAplus and MEDLINE.

Despite advances in targeted anticancer therapies, there are still no small-mol.-based therapies available that specifically target colorectal cancer (CRC) development and progression, the second leading cause of cancer deaths. We previously disclosed the discovery of truncating adenomatous polyposis coli (APC)-selective inhibitor 1 (TASIN-1), a small mol. that specifically targets colorectal cancer cells lines with truncating mutations in the adenomatous polyposis coli (APC) tumor suppressor gene through inhibition of cholesterol biosynthesis. Here, we report a medicinal chem. evaluation of a collection of TASIN analogs and activity against colon cancer cell lines and an isogenic cell line pair reporting on the status of APC-dependent selectivity. A number of potent and selective analogs were identified, including compounds with good metabolic stability and pharmacokinetic properties. The compounds reported herein represent a first-in-class genotype-selective series that specifically target apc mutations present in the majority of CRC patients and serve as a translational platform toward a targeted therapy for colon cancer.

Calvo, Roxan published the artcileFacile access to nitroarenes and nitroheteroarenes using N-nitrosaccharin, Safety of Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Nature Communications (2019), 10(1), 1-8, database is CAplus and MEDLINE.

Nitroaroms. and nitroheteroaroms. serve as key building blocks and intermediates in synthesis, and form the core scaffold of a vast number of materials, dyes, explosives, agrochems. and pharmaceuticals. However, their synthesis relies on harsh methodologies involving excess mineral acids, which present a number of critical drawbacks in terms of functional group compatibility and environmental impact. Modern, alternative strategies still suffer from significant limitations in terms of practicality, and a general protocol amenable to the direct C-H functionalization of a broad range of aromatics has remained elusive. Herein, author introduces a bench-stable, inexpensive, easy to synthesize and recyclable nitrating reagent based on saccharin. This reagent acts as a controllable source of the nitronium ion, allowing mild and practical nitration of both arenes and heteroarenes displaying an exceptional functional group tolerance.
