The 1-benzyl-3,5-bis((E)-3-bromobenzylidene)piperidin-4-one displayed dual p300/EZH2 inhibition joined to cancer-selective cell death in a panel of tumor cells and in in-vivo xenograft models, a series of bis((E)-2-bromobenzylidene) cyclic compounds I (X = CH2) and I (X is NR, where R = H, Me, Bn, etc.) were prepared to test in biochem. (p300, PCAF, SIRT1/2, EZH2, and CARM1) and cellular (NB4, U937, MCF-7, SH-SY5Y) assays. The majority of I exhibited potent dual p300 and CARM1 inhibition, sometimes reaching the submicromolar level, and induction of apoptosis mainly in the tested leukemia cell lines. The most effective compounds in both enzyme and cellular assays carried a 4-piperidone moiety and a Me, benzyl, or acyl substituent at N1 position I [X is NR, where R = H, Me, Bn, 2-oxo-2-phenylethyl, 2-oxo-3-phenylpropyl, 2-oxo-4-phenylbutyl]. Elongation of the benzyl portion to I [X is NR, where R = 2-phenylethyl, 3-phenylpropyl] decreased the potency of compounds at both the enzymic and cellular levels, but the activity was promptly restored by introduction of a ketone group into the phenylalkyl substituent I [X is NR, where R = 2-oxo-2-phenylethyl, 3-oxo-3-phenylpropyl, 4-oxo-4-phenylbutyl]. Western blot analyses performed in NB4 and MCF-7 cells on selected compounds confirmed their inhibition of p300 and CARM1 through decrease of the levels of acetyl-H3 and acetyl-H4, marks for p300 inhibition, and of H3R17me2, mark for CARM1 inhibition.

An Ir(III)-catalyzed [3 + 2] annulation of weakly coordinating N-sulfonyl ketimines with challenging α, β-unsaturated nitro olefins has been achieved via redox-neutral C-H functionalization in the presence of a catalytic amount of silver hexafluoroantimonate. The generation of three consecutive stereogenic centers in a single step via direct C-H functionalization is the prime feature of this methodol. A wide array of pharmaceutically relevant nitro-substituted spirocyclic benzosultams was synthesized with good to excellent diastereoselectivity as well as in high yield starting from easily accessible substrates.

A mild atom-economic visible-light photocatalytic approach was developed for single-step synthesis of diverse aryl alcs., ethers and esters through direct C-H functionalization of aromatic ring at ambient condition. This approach used DDQ as photocatalyst and TBN as co-catalyst to facilitate the substitution of aromatic C-H by neutral nucleophile oxygen of water, alcs. and carboxylic acids and it used aerobic oxygen as the terminal oxidant to produce water as the only byproduct.

Boyd, Derek R.; Sharma, Narain D.; Harrison, John S.; Malone, John. F.; McRoberts, W. Colin; Hamilton, John T. G.; Harper, David B. published the artcile< Enzyme-catalyzed synthesis and reactions of benzene oxide/oxepine derivatives of methyl benzoates>, Related Products of 22717-55-1, the main research area is Phellinus enzyme benzoate ester metabolism.

A series of twelve benzoate esters was metabolized, by species of the Phellinus genus of wood-rotting fungi, to yield the corresponding benzyl alc. derivatives and eight salicylates. The isolation of a stable oxepine metabolite, from Me benzoate, allied to evidence of the migration and retention of a carbomethoxy group (the NIH Shift), during enzyme-catalyzed ortho-hydroxylation of alkyl benzoates to form salicylates, is consistent with a mechanism involving an initial arene epoxidation step. This mechanism was confirmed by the isolation of a remarkably stable, optically active, substituted benzene oxide metabolite of Me 2-(trifluoromethyl)benzoate, which slowly converted into the racemic form. The arene oxide was found to undergo a cycloaddition reaction with 4-phenyl-1,2,4-triazoline-3,5-dione to yield a crystalline cycloadduct whose structure and racemic nature was established by X-ray crystallog. The metabolite was also found to undergo some novel benzene oxide reactions, including epoxidation to give an anti-diepoxide, base-catalyzed hydrolysis to form a trans-dihydrodiol and acid-catalyzed aromatization to yield a salicylate derivative via the NIH Shift of a carbomethoxy group.

Jheng, Li-Cheng; Hsu, Chung-Yen; Yeh, Hong-Yi published the artcile< Anion Exchange Membranes Based on Imidazoline Quaternized Polystyrene Copolymers for Fuel Cell Applications>, Quality Control of 1592-20-7, the main research area is imidazoline quaternized polystyrene copolymer anion exchange membrane fuel cell; anion exchange membranes; fuel cells; imidazoline; polystyrene.

Imidazoline is a five-membered heterocycle derived by the partial reduction of one double bond of the imidazole ring. This work prepared new anion exchange membranes (AEMs) based on imidazoline quaternized polystyrene copolymers bearing N-β-hydroxyethyl oleyl imidazolinium pendent groups to evaluate the application potential for anion exchange membrane fuel cells (AEMFCs). For comparison, an imidazole quaternized polystyrene copolymer was also synthesized. The polymer chem. structure was confirmed by FTIR, NMR, and TGA. In addition, the essential properties of membranes, including ion exchange capacity (IEC), water uptake, and hydroxide conductivity, were measured. The alk. stabilities of imidazolium-based and imidazolinium-based AEMs were compared by means of the changes in the TGA thermograms, FTIR spectra, and hydroxide conductivity during the alk. treatment in 1M KOH at 60°C for 144 h. The results showed that the imidazolinium-based AEMs exhibited relatively lower hydroxide conductivity (5.77 mS/cm at 70°C) but much better alk. stability compared with the imidazolium-based AEM. The imidazolinium-based AEM (PSVBImn-50) retained 92% of its hydroxide conductivity after the alk. treatment. Besides, the fuel cell performance of the imidazolium-based and imidazolinium-based AEMs was examined by single-cell tests.
