Abstract: Currently available chemotherapeutic drugs against hematol. malignancies have several adverse effects and are associated with high mortality rates. Thus, in this study we evaluated the cytotoxic effect of 26 new sulfonamide derivatives on acute leukemia and multiple myeloma cells in order to try to discover a new selective and safe compound that might be used as a prototype for new chemotherapeutic agents. The most cytotoxic compound, DFS16, reduced the cell viability of K562, Jurkat and MM.1S cells in a concentration- and time- dependent manner and it was significantly less cytotoxic to non-tumor cells. On acute leukemia cells, sulfonamide DFS16 activated intrinsic and extrinsic apoptosis with Bax/Bcl-2 inversion, increased FasR expression and m loss. In K562, DFS16 induced apoptosis by caspase-3 activation, while in Jurkat, it induced AIF release and caspase-3 independent apoptosis. In multiple myeloma, DFS16 induced cell cycle arrest at the G2/M phase and apoptosis with m loss. Altogether, the results suggest that the new sulfonamide derivative DFS16 induces apoptotic-like cell death in acute leukemia and multiple myeloma cells. DFS16 is a promising new mol. that could be used as a prototype for the development of chemotherapeutics against hematol. malignancies.

N-Substituted 2-exo-hydroxybornyl-10-sulfonamides, prepared as potential chiral auxiliaries for use in asym. Morita-Baylis-Hillman (MBH) reactions, were treated with acryloyl chloride to afford the corresponding 2-exo-acrylate esters as MBH substrates. Reaction of selected 2-exo-acrylate ester substrates with pyridine-4-carbaldehyde and 6-methylpyridine-2-carbaldehyde in the presence of DABCO gave the expected MBH adducts in >91% yield and with diastereoselectivities of 7-33% d.e.

Wang, Yan-Xiang published the artcileSynthesis and identification of novel berberine derivatives as potent inhibitors against TNF-α-induced NF-κB activation, Name: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Molecules (2017), 22(8), 1257/1-1257/14, database is CAplus and MEDLINE.

Twenty-three new berberine (BBR) analogs containing substituents on ring D, I [R¹ = OMe, NH₂, cyclopropanecarbonyloxy, (4-nitrophenyl)sulfonyloxy, etc., R² = OMe, (adamantan-1-yl)acetoxy, (adamantane-10-carbonyloxy)], were synthesized and evaluated for their activity for suppression of tumor necrosis factor (TNF)-α-induced nuclear factor (NF)-κB activation. Structure-activity relationship (SAR) anal. indicated that suitable tertiary/quaternary carbon substitutions at the 9-position or a rigid fragment at position 10 might be beneficial for enhancing their anti-inflammatory potency. Among them, compounds I [R¹ = (1-methylcyclohexane-1-carbonyl)oxy, 2-(bicyclo[2.2.1]heptan-2-yl)acetoxy, (2′-propylpentanoyl)oxy, (p-tert-butylbenzoyl)oxy, R² = OMe] exhibited satisfactory inhibitory potency against NF-κB activation, with an inhibitory rate of around 90% (5 μM), much better than BBR. A preliminary mechanism study revealed that all of them could inhibit TNF-α-induced NF-κB activation via impairing IκB kinase (IKK) phosphorylation as well as cytokines interleukin (IL)-6 and IL-8 induced by TNF-α. Therefore, the results provided powerful information on further structural modifications and development of BBR derivatives into a new class of anti-inflammatory candidates for the treatment of inflammatory diseases.

A visible-light-initiated radical cascade reaction toward the synthesis of structurally diverse fused indolo-pyridones is described. The reaction involves the addition of aroyl or sulfonyl radicals to N-alkyl-acryloyl-1H-indole-3-carboxamides, cyclization, and oxidative aromatization. This telescoped method circumvents lengthy prefunctionalization steps of radical precursors, which is further underpinned by the superior compatibility with a series of C-centered radicals, allowing the rapid and facile construction of numerous valuable architectures.

The palladium(II)-catalyzed, intramol. alkene hydrofunctionalization reactions with carbon, nitrogen, and oxygen nucleophiles formed five- and six-membered carbo- and heterocycles. In these reactions, the presence of a proximal bidentate directing group controlled the cyclization pathway, dictating the ring size that was generated, even in cases that are disfavored based on Baldwin’s rules and in cases where there is an inherent preference for an alternative pathway. DFT studied shed light on the origins of pathway selectivity in these processes.

Huang, Hong-Gui published the artcileTrifluoromethanesulfonyl azide as a bifunctional reagent for metal-free azidotrifluoromethylation of unactivated alkenes, Safety of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Chemical Science (2021), 12(9), 3210-3215, database is CAplus and MEDLINE.

A simple and metal-free method that rapidly provides these building blocks, e.g., I from abundant alkenes RR¹C=CR²R³ (R = 3-[(pyridin-3-yl)carbonyloxy]propyl, C₈H₁₇, CH₂C₆H₅, etc.; R¹ = H, Me, n-Pr; R² = R³ = H, Me) and trifluoromethanesulfonyl azide (N₃SO₂CF₃). This unprecedented two-component reaction employs readily available N₃SO₂CF₃ as a bifunctional reagent to concurrently incorporate both CF₃ and N₃ groups, which avoids the use of their expensive and low atom economic precursors. A wide range of functional groups, including bio-relevant heterocycles and amino acids, was tolerated. Application of this method was further demonstrated by scale-up synthesis (5 mmol), product derivatization to CF₃-containing medicinal chem. motifs, as well as late-stage modification of natural products, e.g., 5-(2,2,2-trifluoroethyl)pyrrolidin-2-one and drug derivatives

In this paper, we describe the stereospecific synthesis and functional properties of C₂– and C₁-sym. pyrene-fused [5]helicene mols. 1 and 2 connected via hexagonal and heptagonal rings, resp. Both mols. showed high configurational stability and distinct functional properties, which were attributed to the fusing mode of [5]helicene with the pyrene and mol. symmetry. The estimated Gibbs activation energy for enantiomerization of 2 is one of the highest reported values for any π-conjugated mols. incorporating [5]helicene moiety.

The chemoselective oxidation of alcs. containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chem. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant is reported. The superiority of the developed method was demonstrated by comparing it with various conventional alc. oxidation methods.

Employing a green and efficient 2,2,2-trifluoroacetophenone-catalyzed oxidation of alkenes, which utilized H₂O₂ as the green oxidant, a novel and sustainable synthesis of indolines and pyrrolidines was developed. This constituted a cheap, general and environmentally-friendly protocol for the synthesis of substituted nitrogen-containing heterocycles. A variety of substitution patterns, both aromatic and aliphatic moieties, were well tolerated led to the desired nitrogen heterocycles in good to excellent yields.

Kumar, Awanish published the artcileViscosity-Reducing Bulky-Salt Excipients Prevent Gelation of Protein, but Not Carbohydrate, Solutions, SDS of cas: 21286-54-4, the publication is Applied Biochemistry and Biotechnology (2017), 182(4), 1491-1496, database is CAplus and MEDLINE.

The problem of gelation of concentrated protein solutions, which poses challenges for both downstream protein processing and liquid formulations of pharmaceutical proteins, is addressed herein by employing previously discovered viscosity-lowering bulky salts. Procainamide-HCl and the salt of camphor-10-sulfonic acid with L-arginine (CSA-Arg) greatly retard gelation upon heating and subsequent cooling of the model proteins gelatin and casein in water: Whereas in the absence of additives the proteins form aqueous gels within several hours at room temperature, procainamide-HCl for both proteins and also CSA-Arg for casein prevent gel formation for months under the same conditions. The inhibition of gelation by CSA-Arg stems exclusively from the CSA moiety: CSA-Na was as effective as CSA-Arg, while Arg-HCl was marginally or not effective. The tested bulky salts did not inhibit (and indeed accelerated) temperature-induced gel formation in aqueous solutions of all examined carbohydrates-starch, agarose, alginate, gellan gum, and carrageenan.
