Based on the unique property of sulfoximine and the homodimeric C2 structural symmetry of HIV-1 protease, a novel class of sulfoximine-based pseudosymmetric HIV-1 protease inhibitors was designed and synthesized. The sulfoximine moiety was demonstrated to be important for HIV-1 protease inhibitor potency. The most active stereoisomer (2S,2?S) displays a potency of 2.5 nM (IC50) against HIV-1 protease and an anti-HIV-1 activity of 408 nM (IC50). A possible mode of action is proposed.

A previously unreported 1,5-diazacyclooctane-palladium(II) complex was synthesized using bis[ N, N ?-(2-indanolyl)]-1,5-diazacyclooctane, which was readily prepared via a novel [4+4] homocyclization of the unsaturated imine intermediate generated from acrolein and 1-amino-2-indanol. Interestingly, the 1,5-diazacyclooctane-palladium(II) complex self-assembled to form palladium nanoparticles. This approach readily provided palladium nanoparticles simply by heating a mixture of palladium(II) acetate and bis[ N, N ?-(2-indanolyl)]-1,4-diazacyclooctane in dichloroethane at mild temperatures. The 1,5-diazacyclooctane-derivative-palladium nanoparticles were successfully deployed in synthetic applications as a heterogeneous catalyst, facilitating Suzuki coupling and a challenging C-C bond formation via C(sp 3)-H activation under low catalyst loading conditions.

The determination of the enantiopurity and the concentration of chiral compounds by chiroptical sensing with molecular probes is increasingly attractive for high-throughput screening applications including streamlined asymmetric reaction development. In this study, we use stereodynamic aluminum biphenolate complexes for quantitative ee and concentration analysis of amino alcohols and alpha-hydroxy acids. An important feature of the tropos biphenolate ligand used is the presence of phenylacetylene antennae for optimal chirality recognition and CD/UV responses at high wavelengths. The complexation-driven chirality amplification yields strong CD signals which allows quantitative chiroptical sensing with good accuracy. We show that aluminate biphenolate sensors can exhibit linear and nonlinear correlations between the induced CD signals and the enantiomeric composition or concentration of the chiral substrate.

Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring.

The self-association of pyridine and some of its alkyl derivatives (2-, 3- and 4-picoline, 2,4- and 2,6-lutidine, 4-tert-butyl- and 2,6-di-tert-butylpyridine) was studied in aqueous solution, at different pH values, by UV spectroscopy.The variation in molar absorptivity with concentration was measured not only for the main maximum, but also for the different component bands of the absorption band in the mid-UV region (above 200 nm) of these compounds.From the experimental curves of hypochromic effects, self-association constants for dimerization (K2) and polymerization (Kn) were calculated.The results obtained are discussed in detail with relation to the position and nature of alkyl substituents on the pyridine ring.The most relevant result is the influence of alkyl substituents on self-association, particularly the special role of the methyl substituents in ortho positions with respect to the nitrogen atom in 2-picoline, 2,4- and 2,6-lutidine.In 2-picoline and 2,6-lutidine, polymerization can be studied separately from dimerization by measuring the band at longest wavelength, which suggests a possible relationship between the mechanism of formation of polymers and the ?* <- n transitions which give rise to these bands.

In this work, the volatile fraction of unsmoked and smoked Herreno cheese, a type of soft cheese from the Canary Islands, has been characterized for the first time. In order to evaluate if the position in the smokehouse could influence the volatile profile of the smoked variety, cheeses smoked at two different heights were studied. The volatile components were extracted by Solid Phase Microextraction using a divinylbenzene/carboxen/ polydimethylsiloxane fiber, followed by Gas Chromatography/Mass Spectrometry. In total, 228 components were detected. The most numerous groups of components in the unsmoked Herreno cheese were hydrocarbons, followed by terpenes and sesquiterpenes, whereas acids and ketones were the most abundant. It is worth noticing the high number of aldehydes and ketones, and the low number of alcohols and esters in this cheese in relation to others, as well as the presence of some specific unsaturated hydrocarbons, terpenes, sesquiterpenes and nitrogenated derivatives. The smoking process enriches the volatile profile of Herreno cheese with ketones and diketones, methyl esters, aliphatic and aromatic aldehydes, hydrocarbons, terpenes, nitrogenated compounds, and especially with ethers and phenolic derivatives. Among these, methylindanones or certain terpenes like -terpinolene, have not been detected previously in other types of smoked cheese. Lastly, the results obtained suggest a slightly higher smoking degree in the cheeses smoked at a greater height.
