C2-symmetric inhibitors of Plasmodium falciparum plasmepsin II: synthesis and theoretical predictions.

A series of C(2)-symmetric compounds with a mannitol-based scaffold has been investigated, both theoretically and experimentally, as Plm II inhibitors. Four different stereoisomers with either benzyloxy or allyloxy P1/P1′ side chains were studied. Computational ranking of the binding affinities of the eight compounds was carried out using the linear interaction energy (LIE) method relying on a complex previously determined by crystallography. Within both series of isomers the theoretical binding energies were in agreement with the enzymatic measurements, illustrating the power of the LIE method for the prediction of ligand affinities prior to synthesis. The structural models of the enzyme-inhibitor complexes obtained from the MD simulations provided a basis for interpretation of further structure-activity relationships. Hence, the affinity of a structurally similar ligand, but with a different P2/P2′ substituent was examined using the same procedure. The predicted improvement in binding constant agreed well with experimental results.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, HPLC of Formula: C9H11NO, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 126456-43-7

Thermal electric polarization of molecules

The problem of molecular thermal (Pq) polarization estimation in the substances wiih different forms of aggregation and using different experimental techniques is discussed. It is shown on the base of numerous experimental data analysis that Pq includes both rotational (Prot) and orientauonal (Por) components, which may be commensurable in magnitude in gases and gasiform condensed media. The principle of equal distribution of molecules’ thermal polarization over their kinetic degrees of freedom is being satisfied, so Prot, term should not be neglected. The neglect of this fact on estimation of the molecular dipole moments using the first method of Debye results in ?(5/3) or ?/(4/3) times overestimated dipole moment values.

Effect of pyrolysis temperature on the composition of the oils obtained from sewage sludge

Sewage sludge was pyrolysed in a quartz reactor at 350, 450, 550 and 950 C. The pyrolysis oils from the sewage sludge were characterized in detail by means of gas chromatography-mass spectrometry (GC-MS). Changes in the composition of the oils related to the process conditions were assessed by normalizing the areas of the peaks. It was demonstrated that, as the temperature of pyrolysis increased from 350 to 950 C, the concentration of mono-aromatic hydrocarbons in the oils also increased. Conversely, phenol and its alkyl derivatives showed a strong decrease in their concentration as temperature rose. Polycyclic aromatic hydrocarbons (PAHs) with two to three rings passed through a maximum at a pyrolysis temperature of 450 C. PAHs with 4-5 rings also presented a major increase as temperature increased up to 450 C, the concentration at 950 C being slightly higher than that at 450 C. Quantification of the main compounds showed that sewage sludge pyrolysis oils contain significant quantities of potentially high-value hydrocarbons such as mono-aromatic hydrocarbons and phenolic compounds. The oils also contain substantial concentrations of PAHs, even at the lowest temperature of 350 C. The pathway to PAH formation is believed to be via the Diels-Alder reaction and also via secondary reactions of oxygenated compounds such as phenols.

Regioselective CH bond activation on stabilized nitrogen ylides promoted by Pd(II) complexes: Scope and limitations

The orthopalladation of N-ylides [HxCyN-CHC-(O)Ar] (HxCyN = pyridine, benzylamine, imidazole, aniline, and phenylpyridine; Ar = aryl) has been studied. The incorporation of the Pd atom to these substrates is regioselective, since the orthopalladation is produced, in most of the cases, only at the aryl ring of the benzoyl group with concomitant C-bonding of the Nylide. The X-ray structure of one representative example is reported. Factors governing the observed orientation are discussed, because this regioselectivity is worthy of note, considering the deactivating nature of the carbonyl group. Two exceptions to the general trend have been observed. The first one is the double metalation of the ylide [PhMe2NCHC(O)Ph], which incorporates one Pd at each Ph. The second one is the palladation of the phenylpyridine derivative, which occurs at the pyridinic 2-phenyl ring and produces a six-membered palladacycle.

Pyridine- and Quinoline-Based Gold(III) Complexes: Synthesis, Characterization, and Application

Studies on gold(III) coordination of a series of prepared polydentate pyridine and quinoline based ligands are reported. Characterization (1H, 13C, 15N NMR, and XRD) of the novel gold(III) complexes, prepared in 31?98 % yield, revealed different coordination ability of the pyridine and quinoline nitrogen atoms. Testing of catalytic activity in cyclopropanation of propargyl ester and styrene demonstrated that all the new ligated gold(III) complexes were catalytically active and outperformed KAuCl4. The superior activity of the particular Au(III)-pyridine-oxazole complexes may indicate de-coordination of the pyridine-N ligand as a crucial step for efficient generation of catalytic activity.

Hydrogen-bonding interaction of methyl-substituted pyridines with thioacetamide: Steric hindrance of methyl group

The hydrogen-bonding interaction between a series of methyl-substituted pyridines as proton acceptors and thioacetamide as a proton donor in CCl4 has been investigated using near-infrared absorption spectroscopy. The stability of the 1:1 hydrogen-bonded complex increases with the number of methyl groups and depends on the position of methyl groups. The steric hindrance of ortho-methyl groups particularly reduces the stability of complex. The relative stability agrees with the ease of miscibility of pyridines with water for methyl and dimethyl homologs. The calculated proton affinities and the DFT association energies using 6-31+G(d,p) and 6-311++G(2d,2p) basis sets reveal the steric hindrance of ortho-methyl groups.
