Hydrogen-deuterium exchange reactions of aromatic compounds and heterocycles by NaBD4-activated rhodium, platinum and palladium catalysts

Conventional thermal and microwave conditions were compared for hydrogen-deuterium (H/D) exchange reactions of aminobenzoic acids catalysed by NaBD4-activated Pd/C or RhCl3 with D2O as the deuterium source. We also investigated different NaBD4-activated metal catalysts (including Pd/C, RhCl3 and Pt/C) under microwave conditions for an efficient H/D exchange of aromatic and hetero cyclic compounds. Even higher deuterium incorporations were obtained for Pd/C and Pt/C catalyst mixtures due to the previously observed synergistic effect. Finally, we have applied these optimised conditions for one-step syntheses of the MS standards of several pharmaceutically active compounds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 20532-28-9, you can also check out more blogs about20532-28-9

Synthesis and biological evaluation of 2-(alkoxycarbonyl)-3-anilinobenzo[b] thiophenes and thieno[2,3-b]pyridines as new potent anticancer agents

Two new series of inhibitors of tubulin polymerization based on the 2-(alkoxycarbonyl)-3-(3?,4?,5?-trimethoxyanilino)benzo[b] thiophene and thieno[2,3-b]pyridine molecular skeletons were synthesized and evaluated for antiproliferative activity on a panel of cancer cell lines, inhibition of tubulin polymerization, cell cycle effects, and in vivo potency. Antiproliferative activity was strongly dependent on the position of the methyl group on the benzene portion of the benzo[b]thiophene nucleus, with the greatest activity observed when the methyl was located at the C-6 position. Also, in the smaller thieno[2,3-b]pyridine series, the introduction of the methyl group at the C-6 position resulted in improvement of antiproliferative activity to the nanomolar level. The most active compounds (4i and 4n) did not induce cell death in normal human lymphocytes, suggesting that the compounds may be selective against cancer cells. Compound 4i significantly inhibited in vivo the growth of a syngeneic hepatocellular carcinoma in Balb/c mice.

Rhodium-Catalyzed 1,1-Hydroacylation of Thioacyl Carbenes with Alkynyl Aldehydes and Subsequent Cyclization

A rhodium-catalyzed 1,1-hydroacylation of thioacyl carbenes with alkynyl and alkenyl aldehydes and subsequent 6-endo-trig/dig cyclization are realized, giving structurally diverse 4H-thiopyran-4-ones and 2,3-dihydro-4H-thiopyran-4-ones in moderate to good yields. The oxidative addition of Rh(I) to aldehydes is proposed to be the turnover-limiting step.

Sulfonate and sulfamate derivatives possessing benzofuran or benzothiophene nucleus as potent carbonic anhydrase II/IX/XII inhibitors

In the current work, we report the discovery of new sulfonate and sulfamate derivatives of benzofuran- and benzothiophene as potent inhibitors of human carbonic anhydrases (hCAs) II, IX and XII. A set of derivatives, 1a?t, having different substituents on the fused benzofuran and benzothiophene rings (R = alkyl, cyclohexyl, aryl, NH2, NHMe, or NMe2) was designed and synthesized. Most of the derivatives exhibited higher potency than acetazolamide as inhibitors of the purified hCAII, IX and XII isoforms. The most potent inhibitors for hCAII, hCAIX and hCAXII were 1g, 1b and 1d with an IC50 ± SEM values of 0.14 ± 0.03, 0.13 ± 0.03 and 0.17 ± 0.06 muM, respectively. In addition, compounds 1d and 1n exerted preferential inhibitory effect against hCAXII isozyme with good potencies. Some selected compounds were docked within the active pocket of these isozymes and binding of the molecules revealed that sulfonate and sulfamate rings were located towards the active cavity and compounds coordinated to zinc ions.

Synthesis, binding assays, cytotoxic activity and docking studies of benzimidazole and benzothiophene derivatives with selective affinity for the CB2 cannabinoid receptor

Herein we report the design, synthesis, bioinformatic and biological studies of benzimidazole and benzothiophene derivatives as new cannabinoid receptor ligands. To test the hypothesis that the lack of a hydrogen bond interaction between benzimidazole and benzothiophene derivatives with Lys192 reduces their affinity for CB1 receptors (as we previously reported) and leads to CB2 selectivity, most of the tested compounds do not exhibit hydrogen bond acceptors. All compounds displayed mostly CB2 selectivity, although this was more pronounced in the benzimidazoles derivatives. Furthermore, docking assays revealed a ?-cation interaction with Lys109 which could play a key role for the CB2 selectivity index. The series displayed low toxicity on five different cell lines. Derivative 8f presented the best binding profile (Ki = 0.08 muM), high selectivity index (KiCB1/KiCB2) and a low citoxicity. Interestingly, in cell viability experiments, using HL-60 cells (expressing exclusively CB2 receptors), all synthesised compounds were shown to be cytotoxic, suggesting that a CB2 agonist response may be involved.

Pyrrolo[1,4]diazepines, via thermolyse of carbonylazides, and [3,2,2]cyclazines, via Diels-Alder reaction of [f]indolizines, annelated to [1]benzothiophene

Easy access to fused tricyclic pyrrolo[1,2-a][1]benzothieno[2,3-e][1,4]diazepines from the corresponding carbonyl azides by thermolysis in acetic acid is described. Moreover, new [1]benzothieno[2,3(3,2)-f]indolizines were synthesized in one-pot from 2(3)-(2-formylpyrrol-1-ylmethyl)-[1]benzothiophene and with diethyl acetylenedicarboxylate (DEAD) they led regiospecifically to [3,2,2] cyclazines fused to a [1]benzothiophene ring by 1,3-dipolar cycloaddition reaction rather than Diels-Alder adducts.

A biocatalytic method for the chemoselective aerobic oxidation of aldehydes to carboxylic acids

Herein, we present a study on the oxidation of aldehydes to carboxylic acids using three recombinant aldehyde dehydrogenases (ALDHs). The ALDHs were used in purified form with a nicotinamide oxidase (NOx), which recycles the catalytic NAD+ at the expense of dioxygen (air at atmospheric pressure). The reaction was studied also with lyophilised whole cell as well as resting cell biocatalysts for more convenient practical application. The optimised biocatalytic oxidation runs in phosphate buffer at pH 8.5 and at 40 C. From a set of sixty-one aliphatic, aryl-Aliphatic, benzylic, hetero-Aromatic and bicyclic aldehydes, fifty were converted with elevated yield (up to >99%). The exceptions were a few ortho-substituted benzaldehydes, bicyclic heteroaromatic aldehydes and 2-phenylpropanal. In all cases, the expected carboxylic acid was shown to be the only product (>99% chemoselectivity). Other oxidisable functionalities within the same molecule (e.g. hydroxyl, alkene, and heteroaromatic nitrogen or sulphur atoms) remained untouched. The reaction was scaled for the oxidation of 5-(hydroxymethyl)furfural (2 g), a bio-based starting material, to afford 5-(hydroxymethyl)furoic acid in 61% isolated yield. The new biocatalytic method avoids the use of toxic or unsafe oxidants, strong acids or bases, or undesired solvents. It shows applicability across a wide range of substrates, and retains perfect chemoselectivity. Alternative oxidisable groups were not converted, and other classical side-reactions (e.g. halogenation of unsaturated functionalities, Dakin-Type oxidation) did not occur. In comparison to other established enzymatic methods such as the use of oxidases (where the concomitant oxidation of alcohols and aldehydes is common), ALDHs offer greatly improved selectivity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22913-24-2, help many people in the next few years.Application In Synthesis of Methyl benzo[b]thiophene-2-carboxylate
