Subunit-selective proteasome inhibitors are valuable tools to assess the biological and medicinal relevance of individual proteasome active sites. Whereas the inhibitors for the beta 1c, beta 1i, beta 5c, and beta 5i subunits exploit the differences in the substrate-binding channels identified by X-ray crystallography, compounds selectively targeting beta 2c or beta 2i could not yet be rationally designed because of the high structural similarity of these two subunits. Here, we report the development, chemical synthesis, and biological screening of a compound library that led to the identification of the beta 2c- and beta 2i-selective-compounds LU-002c (4; IC50 beta 2c: 8 nM, IC50 beta 2i/beta 2c: 40-fold) and LU-002i (5; IC50 beta 2i: 220 nM, IC50 beta 2c/beta 2i: 45-fold), respectively. Co-crystal structures with beta 2 humanized yeast proteasomes visualize protein-ligand interactions crucial for subunit specificity. Altogether, organic syntheses, activity-based protein profiling, yeast mutagenesis, and structural biology allowed us to decipher significant differences of beta 2 substrate-binding channels and to complete the set of subunit-selective proteasome inhibitors.

A series of imidazolium-based palladate precatalysts has been synthesized and the catalytic activity of these air- and moisture-stable complexes evaluated as a function of the nature of the imidazolium counterion. These precatalysts can be converted under catalytic conditions to Pd-NHC species capable of enabling the Buchwald-Hartwig aryl amination and the alpha-arylation of ketones. Both reactions can be carried out efficiently under very mild operating conditions. The effectiveness of the protocol was tested on functionality-laden substrates.

Non-steroidal anti-inflammatory drugs are among the most used drugs. They are competitive inhibitors of cyclooxygenase (COX). Twelve novel compounds (aryl acetate and aryl acetic acid groups) were synthesized in this work in order to identify which one was the most potent and which group was most selective towards COX1 and COX2 by using an in vitro COX inhibition assay kit. The cytotoxicity was evaluated for these compounds utilizing MTS assay against cervical carcinoma cells line (HeLa). The synthesized compounds were identified using FTIR, HRMS,H-1-NMR, and(13)C-NMR techniques. The results showed that the most potent compound against the COX1 enzyme was 4f with IC50 = 0.725 mu M. The compound 3b showed potent activity against both COX1 and COX2 with IC50 = 1.12 and 1.3 mu M, respectively, and its selectivity ratio (0.862) was found to be better than Ketoprofen (0.196). In contrast, compound 4d was the most selective with a COX1/COX2 ratio value of 1.809 in comparison with the Ketoprofen ratio. All compounds showed cytotoxic activity against the HeLa Cervical cancer cell line at a higher concentration ranges (0.219-1.94 mM), and the most cytotoxic compound was 3e with a CC(50)value of 219 mu M. This was tenfold more than its IC(50)values of 2.36 and 2.73 mu M against COX1 and COX2, respectively. In general, the synthesized library has moderate activity against both enzymes (i.e., COX1 and COX2) and ortho halogenated compounds were more potent than the meta ones.

Preparation of an ordered mesoporous polypyrrole/carbon (PPy/OMC) composite has been described through a two-step nanocasting process using KIT-6 as a template. Characterization of the PPy/OMC nanocomposite by various analysis methods such as TEM, XRD, TGA, SEM and N-2 sorption confirmed the preparation of a material with ordered mesoporous structure, uniform pore size distribution, high surface area and high stability. This nanocomposite was then used for the immobilization of palladium nanoparticles. The nanoparticles were almost uniformly distributed on the support with a narrow particle size of 20-25 nm, confirmed by various analysis methods. Performance of the Pd@PPy/OMC catalyst was evaluated in the aerobic oxidation of various primary and secondary alcohols on water as a green solvent, giving the corresponding carboxylic acids and ketones in high yields and excellent selectivity. The catalyst could also be reused for at least 10 reaction runs without losing its catalytic activity and selectivity. High catalytic efficiency of the catalyst can be attributed to a strong synergism between the PPy/OMC and that of supported Pd nanoparticles.

A simple, efficient, sustainable and economical method for the oxidation of alcohols and amines has been developed based on chloride, a sea abundant anionic catalyst for the practical synthesis of a wide range of carboxylic acids, ketones and imines. Oxidation of aromatic alcohols was carried out using NaCl (20 mol%) as the catalyst, NaOH (50 mol%) and aq. TBHP (4 equiv.) as the oxidant in 55-92% isolated yields. Oxidation of aromatic amines to imines was achieved by using only 20 mol% of NaCl and aq. TBHP (4 equiv.) in 32-93% isolated yields. The chlorine species formed during the reaction as the active oxidation catalyst has been identified as ClO2- for alcohols and ClO-/ClO2- for amines by control experiments. This method is mostly free from chromatographic purification, which makes it suitable for large-scale synthesis. We have scaled up to 30 gram scale the synthesis of carboxylic acids and imines in good yields and have also carried out efficiently this new method using filtered sea water as the solvent and catalyst.

Piper nigrumL. is a widely used spice because of its flavour and health effects. It is prepared as black and white pepper, according to the harvest time and inclusion of the outer skin. Pepper pericarp is usually considered waste when making white pepper. In this study, bioactive and flavour compounds and minerals in the pericarp of black pepper were determined to identify its applications. The pericarp contained total phenol, total flavonoid and piperine contents of 1421.95 +/- 22.35 mg GAE/100 g, 983.82 +/- 8.19 mg CE/100 g and 2352.19 +/- 68.88 mg/100 g, respectively. There were higher levels of total phenols and total flavonoids in the pericarp compared with black pepper and white pepper. Piperine content was lower in the pericarp than in black pepper. The principal monoterpene compounds in the pericarp were alpha-pinene (9.2%), 2-beta-pinene (14.3%), delta-3-carene (21.5%) anddl-limonene (18.8%), and the primary sesquiterpenes were alpha-copaene (5.1%) and caryophyllene (17.2%). The higher percentages of flavour compounds found in the pericarp would impart a more potent odour, and the pericarp exhibited higher minor and tiny differences based on electronic nose analysis. It had more minerals than black pepper and peeled black pepper.

In this study, we introduced 1, 2, 4-triazole groups into panaxadiol (PD) to obtain 18 panaxadiol triazole derivatives. Five cancer cells and one normal cell were evaluated for cytotoxicity by MTT assay. The results showed that most of the derivatives could inhibit cancer cell proliferation, and the anti-proliferative activity of compound A1 was the most significant. For HepG-2 cells, the IC50 value was 4.21 +/- 0.54 mu M, which was nearly 15 times higher than the activity of PD. Further studies showed that compound A1 could induce apoptosis in HepG-2 cells, and could enhance the expression of Cl-caspase-3, Cl-caspase-9 and Cl-PARP. Moreover, Western blot analysis showed that after treating HepG-2 cells with compound A1, the expression of p53 protein was increased and the ratio of Bax/Bcl-2 was gradually increased. The cytoplasmic Bax is then translocated to the mitochondria, causing the release of Cyt c protein. Therefore, the results indicate that compound A1 induces apoptosis through the mitochondrial pathway and can be used the potential to develop new anti-proliferative agents.
