Darroudi, Mahdieh published the artcileSynthesis of Novel Triazole Incorporated Thiazolone Motifs Having Promising Antityrosinase Activity through Green Nanocatalyst CuI-Fe₃O₄@SiO₂ (TMS-EDTA), COA of Formula: C7H7ClN2S, the publication is Applied Organometallic Chemistry (2020), 34(12), e5962, database is CAplus.

In the present work, novel 5-((1-benzyl-1,2,3-triazol-4-yl)methoxybenzylidene)-2-(arylamino)thiazol-4-one thiazolone incorporated triazole derivatives I and II was designed as tyrosinase inhibitors. The compounds I and II were synthesized through click reaction in good yield. Moreover, the antityrosinas activity of the synthesized derivatives I and II was evaluated. In the search for establishing a click copper-catalyzed azide/alkyne cycloaddition (CuAAC) reaction under strict conditions, in terms of a novel air-stable, a recyclable and efficient magnetic catalyst was planned for new triazole derivatives as a well-organized copper iodide supported on the functionalized Fe₃O₄@SiO₂ core-shell (CuI/Fe₃O₄@SiO₂(TMS-EDTA) nanoparticles). The engineered nanocatalyst synthesized for the first time and characterized by different methods, including FT-IR spectroscopy, XRD, FESEM, EDX, TEM, TGA, and BET anal. The excellent catalytic performance in ethanol with high surface area (351.7 m²g^-1) and short reaction time for diverse functional groups (120-200 min), no use of toxic solvents, reusability of the catalyst, and using eco-friendly conditions were the advantageous of this work. Moreover,the nanocatalyst was used at least five times without any significant decrease in the yield of the reaction. The thiazolidine-triazole derivatives I [X=Y=Z = H, X=Y = H; Z = Br, X = 4-N; Y = H; Z = 2-Cl and X = 4-N; Y = H; 3,4-di-Cl] showed promising tyrosinase inhibitory activity with IC₅₀ values in the range of 5.90-9.81μM. The compounds I and II were found to be considerably more potent tyrosinase inhibitors than the reference inhibitor kojic acid (IC₅₀ = 18.36μM).

Ahn, Ki Chang published the artcileDetection of the Antimicrobial Triclosan in Environmental Samples by Immunoassay, Category: chlorides-buliding-blocks, the publication is Environmental Science & Technology (2016), 50(7), 3754-3761, database is CAplus and MEDLINE.

A sensitive, competitive ELISA for the detection of the antimicrobial triclosan (TCS) was developed. Novel immunizing haptens were synthesized by derivatizing at the 4-Cl position of the TCS mol. Compounds derived from substitutions at 4′-Cl and that replaced the 2′-OH with a Cl atom were designed as unique coating antigen haptens. Polyclonal rabbit antisera were screened against the coating antigen library to identify combinations of immunoreagents resulting in the most sensitive assays. The most sensitive assay identified was one utilizing antiserum number 1155 and a heterologous competitive hapten, where the 2′-OH group was substituted with a Cl atom. An IC₅₀ value and the detection range for TCS in assay buffer were 1.19 and 0.21-6.71 μg/L, resp. The assay was selective for TCS, providing low cross-reactivity (<5%) to the major metabolites of TCS and to brominated di-Ph ether-47. A 2nd assay using a competitive hapten containing Br instead of Cl substitutions was broadly selective for both brominated and chlorinated diphenylethers. Using the most sensitive assay combination, we measured TCS concentrations in water following dilution Biosolid samples were analyzed following the dilution of a simple solvent extract The immunoassay results were similar to those determined by LC-MS/MS. This immunoassay can be used as a rapid and convenient tool to screen for human and environmental exposure.

Prasad, G. K. published the artcileSun light assisted photocatalytic decontamination of sulfur mustard using ZnO nanoparticles, Application of 1,2-Bis(2-chloroethyl)disulfane, the publication is Journal of Molecular Catalysis A: Chemical (2011), 349(1-2), 55-62, database is CAplus.

Sunlight-assisted photocatalytic decontamination of sulfur mustard (HD) was studied using ZnO nanoparticles and the data were compared with those carried out in the presence of UVA and visible light radiation. In the presence of sunlight, 100% of HD was decomposed in 12 h. Whereas, in the presence of UVA light 90%, and in visible light 80% of HD was decomposed in 12 h. GC-MS data indicated the formation of thiodiglycol, hemisulfur mustard, divinyl sulfide, 2-chloro Et vinyl sulfide, etc., on the surface of ZnO nanoparticles in the case of dark and visible light irradiation experiments However, in sunlight and UVA light irradiation experiments, GC-MS data indicated the formation of HD sulfoxide, HD sulfone, 1,3-dithiane, 2-chloro ethanol, acetaldehyde, CO₂, etc. along with hydrolysis and elimination products. Under the illumination of visible light and in dark hydrolysis, elimination and surface complexation reactions contributed to decontamination of HD. Whereas, in the presence of sunlight and UVA light, photocatalytic reactions like C-S bond cleavage, oxidation of C, S atoms were observed to have contributed to decontamination of HD in addition to hydrolysis and elimination reactions.

Comstock, Lindsay R. published the artcileExpeditious synthesis of aziridine-based cofactor mimics, Name: 2,3-Dibromopropionylchloride, the publication is Tetrahedron (2002), 58(30), 6019-6026, database is CAplus.

S-Adenosyl-L-methionine mimics were synthesized in a linear fashion highlighting methodol. that bypasses the need for adenine base protection. These aziridine-based cofactor mimics are envisioned as useful biochem. tools and potential therapeutic agents whose mechanism of action hinges upon aberrant methyltransferase enzymes. Aziridination of the 5′ position of adenosine was effected by convergence of suitably protected 5′-aminoadenosine with various dibromopropionates. The economy and high yields for this route to said aziridine-based cofactors is highly amenable to large-scale chem. which no doubt will be vital to their development as therapeutics and biochem. tools.

Nielsen, Alexander L. published the artcileMechanism-based inhibitors of SIRT2: structure-activity relationship, X-ray structures, target engagement, regulation of α-tubulin acetylation and inhibition of breast cancer cell migration, Quality Control of 42074-68-0, the publication is RSC Chemical Biology (2021), 2(2), 612-626, database is CAplus and MEDLINE.

Sirtuin 2 (SIRT2) is a protein deacylase enzyme that removes acetyl groups and longer chain acyl groups from post-translationally modified lysine residues. It affects diverse biol. functions in the cell and has been considered a drug target in relation to both neurodegenerative diseases and cancer. Therefore, access to well-characterized and robust tool compounds is essential for the continued investigation of the complex functions of this enzyme. Here, we report a collection of chem. probes that are potent, selective, stable in serum, water-soluble, and inhibit SIRT2-mediated deacetylation and demyristoylation in cells. Compared to the current landscape of SIRT2 inhibitors, this is a unique ensemble of features built into a single compound We expect the developed chemotypes to find broad application in the interrogation of SIRT2 functions in both healthy and diseased cells, and to provide a foundation for the development of future therapeutics.

Di Carmine, Graziano published the artcileSynthesis of functionalized imidazolidine-2-thiones via NHC/base-promoted aza-benzoin/aza-acetalization domino reactions, Name: 1-(4-Chlorophenyl)thiourea, the publication is Organic & Biomolecular Chemistry (2017), 15(41), 8788-8801, database is CAplus and MEDLINE.

A strategy for the synthesis of biol. relevant 5-hydroxy-imidazolidine-2-thione derivatives I [R¹ = i-Pr, 4-pyridinyl, 2-ClC₆H₄, etc.; R² = i-Pr, Ph, 2-FC₆H₄, 4-ClC₆H₄, 3-MeC₆H₄, 3-BrC₆H₄; R³ = cyclohexyl, Ph, 2-MeC₆H₄, 2-FC₆H₄, 4-ClC₆H₄; X = S] and imidazolidine-2-one I [R¹ = Ph; R² = 4-ClC₆H₄; R₃ = Bn; X = O] was presented. A novel class of α-sulfonylamines had been suitably prepared (46-81% yield) as precursors of formal benzylidenethiourea acceptors; these were generated in situ and intercepted by N-heterocyclic carbene (NHC)-activated aldehydes affording open-chain aza-benzoin-type adducts, which in turn underwent an intramol. aza-acetalization reaction in a one-pot fashion. A thiazolium salt/triethylamine couple proved to be the more effective system to trigger the domino sequence giving the target heterocycles in good yields (45-97%) and diastereoselectivities (up to 99 : 1 dr). The multigram scale synthesis and elaboration of a selected 5-hydroxy-imidazolidine-2-thione compound I [R¹ = 4-ClC₆H₄, R² = R³ = Ph] was also described.
