Thermodynamic Similarity of Phase-Separation Binary Solutions with a Lower Critical Temperature

The termodynamic similarity of phase-separating binary aqueous solutions with a lower critical solution temperature is discussed.The values of temperature and pressure at the double critical point are used as scales.An analysis of the experimental material on the phase-separation of aqueous solutions of organic compounds has discovered correlations between dimensionless thermodynamic complexes that make it possible to calculate the line of the critical points (LCP) of a solution by the data on phase-separation at atmospheric pressure.The proposed algorithm of calculation is verified by the example of the mixture water/2,6-dimethylpyridine.The calculated and the experimental data for the LCP of this solution demonstrate a satisfactory agreement. keywords Aqueous solutions / Phase-separation / Double critical point / Thermodynamic similarity

Two-carbon-elongated HIV-1 protease inhibitors with a tertiary-alcohol- containing transition-state mimic

A new generation of HIV-1 protease inhibitors encompassing a tertiary-alcohol-based transition-state mimic has been developed. By elongation of the core structure of recently reported inhibitors with two carbon atoms and by varying the P1? group of the compounds, efficient inhibitors were obtained with Ki down to 2.3 nM and EC50 down to 0.17 muM. Two inhibitor-enzyme X-ray structures are reported.

Versatile chiroptics of peptide-induced assemblies of metalloporphyrins

Zinc porphyrin functionalized with double long-chain alkylated l-glutamide (GTPP-Zn) was synthesized for the first time, and its self-assembling behaviour was investigated in nonpolar organic solvents. The uniqueness of this functionalized porphyrin is characterized by its drastic colour change from dark green to purple via the formation of chirally stacked structures through selective axial coordination on zinc with pyridine derivatives. In this paper, we report the versatility of the GTPP-Zn assembly process as a stimuli-responsive chiroptical switching system and describe the remarkable ligand-specific induction of secondary chirality accompanied by aggregation morphological change.

Method validation parameters for drugs and explosives in ambient pressure ion mobility spectrometry

An approach using method validation (MV) parameters, otherwise known as analytical figures of merit was combined with electrospray ionization high performance ion mobility spectrometry (ESI-HPIMS) to describe an approach for evaluating drugs and explosives analysis in the field. MV parameters such as reduced mobility (Ko), conditional reduced mobility (Kc), resolving power (Rp), theoretical plates (N), linearity, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), repeatability, range, and reporting limit were investigated and developed for eleven drugs and six explosives. Our investigation estimated resolving power at 66 ¡À 0.64 for the ESI-HPIMS used. The LOD?s calculated ranged from 0.45?2.97?ng of material electrosprayed into the ESI-HPIMS. The LOQ?s calculated falls in the range 4.11?8.63?ng of material electrosprayed into the ESI-HPIMS. The key findings from this investigation were the following: Kc proves to be a measure of the identity of an explosive or drug ion; a parameter that may be applied to help aid IMS devices when detecting drugs and explosives. MV parameters, especially, Kc, introduced in this study is an effective parameter for establishing a unique identity of a drug or explosive. A control chart is an effective way to monitor the performance of an instrument and may be a useful tool for establishing reliability of confirmatory data in forensic investigations. MV parameters may be a reliable, accurate and unique identification marker for target drugs and explosives capable of differentiating these substances from false positive responses.

Preferential enclathration of lutidine isomers by diol-hosts

The Host compound 2,2? bis(1-hydroxy-4,5-dihydro-2,3:6,7-dibenzocycloheptatrien-1-yl)-biphenyl, H1, has been employed to discriminate between all the pairs of lutidine isomers. The preference for guest enclathration follows the sequence 3,4-LUT>2,4-LUT?3,5-LUT>2,5-LUT>2,3-LUT>2,6-LUT. This has been confirmed by guest-release endotherms measured by DSC. Four other diol host compounds, H2?H5, were tested on pairs of lutidine isomers which were poorly separated by H1.

Catalytic asymmetric bromochlorination of aromatic allylic alcohols promoted by multifunctional Schiff base ligands

It was found that the tridentate O,N,O-type Schiff base ligand bearing suitable substituents was a highly effective promoter in the catalytic asymmetric bromochlorination reaction, in which the corresponding aromatic bromochloroalcohols with vicinal halogen-bearing stereocenters were formed with perfect regioselectivity, with moderate to excellent enantioselectivities (up to 93% ee), and with good yields and chemoselectivities.

Planar chiral ferrocene salen-type ligands featuring additional central and axial chirality

We report on novel chiral tridentate [NO2]H2 and tetradentate [N2O2]H2 Schiff base ligands containing a planar chiral ferrocene moiety linked to hydroxyl-imine or diimine donors with central or axial chirality. Structurally, these ligands resemble half-salen and salen systems designed for stereoselective applications of their transition metal complexes in homogeneous catalysis. The modular synthesis involves diastereoselective metalation of chiral ferrocene or pentamethylferrocene acetals, followed by stereoconservative hydroxyalkylation and condensation with chiral hydroxyamines or diamines, respectively. In comparison to salen-type systems, an important advantage of these ligands is their tunable steric protection of the alkoxide donor site. A total of 18 different ligands varying in electronic and steric properties have been prepared and fully characterized by NMR, IR, mass spectroscopy and by single crystal structure analysis of nine precursors and representatives.
