Akgul, Ozlem published the artcileSultam based Carbonic Anhydrase VII inhibitors for the management of neuropathic pain, Safety of 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is European Journal of Medicinal Chemistry (2022), 113956, database is CAplus and MEDLINE.

We report a series of compounds 1-17 derived from the antiepileptic drug Sulthiame (SLT) from which both the benzenesulfonamide and the sultam moiety were retained. All compounds were tested in vitro for their inhibition activity against the human (h) Carbonic Anhydrase (CA; EC 4.2.1.1) I, II, VII, IX and XII isoforms. Among the series, derivatives 1 and 11 showed great enhancement of both inhibition potency and selectivity towards the hCA VII isoform, when compared to the reference SLT drug. The binding mode of 11 within the hCA VII active site was deciphered by means of X-ray crystallog. and revealed the sultam moiety being exposed to the rim of the active site. In vivo experiments on a model of neuropathic pain induced by oxaliplatin clearly showed 11 being an effective pain relieving agent and therefore worth of further exploitation towards the validation of the hCA VII as new target for the management of neuropathies.

Woodring, Jennifer L. published the artcileDisrupting the Conserved Salt Bridge in the Trimerization of Influenza A Nucleoprotein, Formula: C7H7ClN2S, the publication is Journal of Medicinal Chemistry (2020), 63(1), 205-215, database is CAplus and MEDLINE.

Antiviral drug resistance in influenza infections has been a major threat to public health. To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339…R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC₅₀ = 2.7μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based approach and performed antiviral activity screening to identify compounds 29 and 30 with EC₅₀ values of 110 and 120 nM, resp., and without measurable host cell cytotoxicity. Compared to the clin. used neuraminidase inhibitors, these two compounds showed better activity profiles against drug-resistant influenza A strains, as well as influenza B, and improved survival of influenza-infected mice.

A palladium-catalyzed intramol. Heck/aminocarbonylation of alkene-tethered iodobenzenes 2-I-4-R-5-R¹-C₆H₂XCH₂C(CH₃)=CH₂ [R = H, F, Cl, Me, etc.; R¹ = H, Cl, OMe, C(O)OMe; X = O, NMe, NBn, NTs] with nitro compounds R²NO₂ (R² = Me, Ph, naphthalen-2-yl, 2H-1,3-benzodioxol-5-yl, etc.) has been developed for the synthesis of carbamoyl substituted benzoheterocycles I. Using Mo(CO)₆ as a solid CO source, no external reductant or additives were needed in this procedure. Both nitroarenes and nitroalkanes were well tolerated. A range of carbamoyl-substituted dihydrobenzofurans I (X = O) and indolines I (X = NMe, NBn, NTs) were prepared in moderate to high yields.

Ma, Zhuang published the artcileTungstate-Catalyzed Biomimetic Oxidative Halogenation of (Hetero)Arene under Mild Condition, Computed Properties of 36335-47-4, the publication is iScience (2020), 23(5), 101072, database is CAplus and MEDLINE.

A biomimetic approach for halogenation (Br, Cl, I) of (hetero)arene catalyzed by tungstate under mild pH in a cost-efficient and environment- and operation-friendly manner was reported. Broad substrates diverse functional group tolerance and good chemo- and regioselectivities were observed, even in late-stage halogenation of complex mols. Moreover, this approach was scaled up to over 100 g without time-consuming and costly column purification Several drugs and key precursors for drugs bearing aryl halides (Br, Cl, I) was conveniently prepared based on this approach.

Sutherland, Hamish S. published the artcileSynthesis and structure-activity relationships for a new class of tetrahydronaphthalene amide inhibitors of Mycobacterium tuberculosis, Related Products of chlorides-buliding-blocks, the publication is European Journal of Medicinal Chemistry (2022), 114059, database is CAplus and MEDLINE.

Drug resistant tuberculsosis (TB) is global health crisis that demands novel treatment strategies. Bacterial ATP synthase inhibitors such as bedaquiline and next-generation analogs (such as TBAJ-876) have shown promising efficacy in patient populations and preclin. studies, resp., suggesting that selective targeting of this enzyme presents a validated therapeutic strategy for the treatment of TB. In this work, we report tetrahydronaphthalene amides (THNAs) as a new class of ATP synthase inhibitors that are effective in preventing the growth of Mycobacterium tuberculosis (M.tb) in culture. Design, synthesis and comprehensive structure-activity relationship studies for approx. 80 THNA analogs are described, with a small selection of compounds exhibiting potent (in some cases MIC90 <1 μg/mL) in vitro M.tb growth inhibition taken forward to pharmacokinetic and off-target profiling studies. Ultimately, we show that some of these THNAs possess reduced lipophilic properties, decreased hERG liability, faster mouse/human liver microsomal clearance rates and shorter plasma half-lives compared with bedaquiline, potentially addressing of the main concerns of persistence and phospholipidosis associated with bedaquiline.

Sone, Toshihiko published the artcileCatalytic asymmetric synthesis of 2,2-disubstituted oxetanes from ketones by using a one-pot sequential addition of sulfur ylide, Safety of trimethyloxosulphonium chloride, the publication is Angewandte Chemie, International Edition (2009), 48(9), 1677-1680, database is CAplus and MEDLINE.

Enantiopure 2-Me-2-R-substituted oxetanes (R = n-octyl, 9-decenyl, cyclohexyl, Ph, 4-ClC₆H₄, 4-FC₆H₄, PhCH₂CH₂, 2-naphthyl) were synthesized from the corresponding ketones RCOMe and dimethyloxosulfonium methylide via one-pot double methylene transfer catalyzed by a heterobimetallic La/Li complex. Chiral amplification in the second step was the key to obtain oxetanes in high enantiomeric excess.

Luo, Jun published the artcileHydrocarbon Waxes from a Salt in Water: The C1 Polymerization of Trimethylsulfoxonium Halide, Safety of trimethyloxosulphonium chloride, the publication is ACS Macro Letters (2012), 1(5), 560-563, database is CAplus and MEDLINE.

We report the synthesis of polymethylene waxes, a surrogate of PE waxes, by a controlled polymerization reaction in water at or near r.t. and under atm. pressure. The monomer, dimethylsulfoxonium methylide, is generated in situ from a salt, trimethylsulfoxonium halide. The carbon sources for the polymerizations are C1 mols., which can be derived from nonpetroleum feedstock. DMSO serves as the C1 carrier and is not consumed. The reaction is initiated and catalyzed by trialkylboranes, compounds that are stable in water. A certain degree of mol. weight control is achieved by adjusting the stoichiometry of “salt” to organoborane. Polymethylene, the simplest hydrocarbon polymer, is a semicrystalline material. The room temperature polymerization produces a linear polymer approx. 100°C below its melting temperature (T_m). The supercooled polymers rapidly crystallize into flat nanoparticles comprised of stacked lamellae.

Sanin, P. I. published the artcileAntiwear additives of phosphonate type, Application of Diethyltrichloromethylphosphonate, the publication is Neftekhimiya (1974), 14(2), 317-22, database is CAplus.

The effectiveness of esters of phosphonic acids depended on their structure and on the friction regime. The esters containing no Cl had no effect at high and low loads. Those containing CCl3 groups were effective at both high and low loads or only at high and only at low ones. The difference was assumed to be due to different chem. and adsorption activity of the compounds and chem. modification of the friction surface. The effectiveness depended on the concentration of additive (1.5-6 mmole/100 g oil).
