Kinase domain inhibition of leucine rich repeat kinase 2 (LRRK2) using a [1,2,4]triazolo[4,3-b]pyridazine scaffold

Leucine rich repeat kinase 2 (LRRK2) has been genetically linked to Parkinson’s disease (PD). The most common mutant, G2019S, increases kinase activity, thus LRRK2 kinase inhibitors are potentially useful in the treatment of PD. We herein disclose the structure, potential ligand-protein binding interactions, and pharmacological profiling of potent and highly selective kinase inhibitors based on a triazolopyridazine chemical scaffold.

A comparative study of the coordination of saccharinate, thiosaccharinate and benzisothiozolinate ligands to cyclometalated [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2: Molecular structures of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-X)]2 (X?=?sac, bit and tsac) and [Pd(Me2NCH2C6H4-kappa2N,C)Cl(ampyH-kappa1N)] (ampyH?=?2-amino-3-methylpyridine)

Reactions of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2 with two equivalents of sodium saccharinate (Nasac), thiosaccharin (Htsac) or sodium benzisothiozolinate (Nabit) results in the stepwise substitution of the bridging halides to form sequentially [Pd2(Me2NCH2C6H4-kappa2N,C)2(mu-Cl)(mu-X)] (X = sac, tsac) and [Pd(Me2NCH2C6H4-kappa2N,C)(mu-X)]2 (X = sac, tsac, bit). The molecular structures of all three disubstituted complexes are reported. In each the two metalated ligands bind in a chelate manner adopting a relative anti conformation, while the new ligands bridge the two palladium atoms adopting a relative cis conformation. The local conformation about each palladium differs with small ligand changes. Thus in the sac and bit complexes all nitrogens lie trans to one another, in the tsac complex they are cis. Conformational changes also lead to large differences in the non-bonded Pd?Pd distance which range over 0.5 A. Treatment of [Pd(Me2NCH2C6H4-kappa2N,C)(mu-Cl)]2 with two equivalents of 2-amino-3-methylpyridine (ampyH) in the presence of NEt3 affords mononuclear [PdCl(Me2NCH2C6H4-kappa2N,C)(ampyH-kappa1N)] as a result of ?bridge-splitting?, the ampyH ligand binding through the pyridyl-nitrogen and lying approximately perpendicular to the PdCClN2 plane as shown by a crystallographic study.

Complete study of the pyrolysis and gasification of scrap tires in a pilot plant reactor

The pyrolysis and gasification of tires was investigated in a pilot plant reactor provided with a system for condensation of semivolatile matter. The study comprised experiments at 450, 750, and 1000C both in nitrogen and 10% oxygen atmospheres. In the gas phase, only methane and benzene yields increased with temperature until 1000C. In the liquids, the main components were styrene, limonene, and isoprene. The solid fraction (including soot) increased with temperature. Zinc content of the char decreased with increasing temperature. Analysis of the surface area of the solids showed that the area was similar in all cases to that of a commercial carbon black. The higher surface of the soot with respect to the chars was observed. The results coincided with published findings, i.e., kinetic severity function values would produce 0.2% of methane at 450C and 4.5% at 750-1000C.

Time-Resolved Photoelectron Studies of Thiophene and 2,5-Dimethylthiophene

The photoinduced dynamics of thiophene and 2,5-dimethylthiophene (2,5-DMT) were investigated upon excitation at 200 and 255 nm (2,5-DMT only) using time-resolved photoelectron spectroscopy and compared with results from ab initio coupled cluster calculations. For thiophene, depopulation of the initially excited B2(pi3pi4?) state to the lower-lying A1(pi2pi4?) state occurs within 25 ¡À 20 fs, with a subsequent bifurcation into a ring-puckering channel and a ring-opening channel with lifetimes of 80 ¡À 20 and 450 ¡À 50 fs, respectively. For 2,5-DMT, the dynamics following excitation at 200 nm is described by a monoexponential decay with a time constant of 120 ¡À 20 fs, while that following excitation at 255 nm is best fit by a biexponential decay with time constants of 115 ¡À 20 fs and 15 ¡À 3 ps, respectively. The fast signal observed after excitation of 2,5-DMT is assigned to the ring-opening channel, which is favored with respect to thiophene due to a lower excited-state barrier along the ring-opening coordinate and an increased inertia toward the ring-puckering channel. Coupled cluster calculations have been undertaken to compare the relaxation dynamics of thiophene to thiazole and isothiazole. For the latter two molecules, we find a strong gradient along the ring-opening coordinate in the Franck-Condon region of the initially populated pipi? state and predict that ring-opening is the dominating relaxation channel after photoexcitation. We use the extracted information for a comparison of the thiophene dynamics with the light-induced processes observed in other five-membered heterocyclic molecules.

Characterization of Aroma Compounds in Two Meat Flavorings Prepared from Thermal Reaction of Enzymatic Hydrolysates of Black Pig and Common White Pig Meat Proteinss with Oxidized Lard

Meat flavorings were prepared by thermal reactions of enzymatic hydrolysates of black pig and common white pig (large white) meat proteins with oxidized lard. The volatile compounds of the two meat flavorings were analyzed by solvent assistant flavor distillation (SAFE) combined with gas chromatography and mass spectrometry (GC-MS). Based on retention indices and mass spectra, a total of 123 volatile compounds, including sulfur-containing compounds, nitrogencontaining heterocycles, oxygen-containing heterocycles, aldehydes, ketones, alcohols, acids, esters and hydrocarbons, were identified. In comparison, the white pig meat-derived flavoring had a greater percentage (relative to the total peak area) of alkyl furanes, aliphatic aldehydes and acids while the black pig meat-derived flavoring had a greater percentage of sulfur-containing compounds, nitrogen-containing heterocycles, and esters. However, their relative contents of ketones and alcohols were similar. Furthermore, by gas chromatography-olfactometry (GC-O), a total of 31 odor-active compounds were identified through comparison of their retention indices and odor characteristics with those of authentic standards. Among them, 28 compounds were common to two meat flavorings, and in particular dimethyltrisulfide, furfuryl mercaptan, 3-ethyl-2,5-dimethylpyrazine, 3-(methylthio) propanal,2-ethylthiophene,(E,E)-2,4-decadienal,(E)-2-decenal,(E)-2-nonenal,1-octen-3-ol and 3-hydroxy-2-butanone had high flavor dilution (FD) factors. However, the number of compounds with high FD values was greater in the black pig meat-derived flavoring than in the white pig meat-derived flavoring. Additionally, the spider-web plots for the potent odor-active compounds revealed that the black pig meat-derived flavoring had higher scores for meaty and fatty odors than the black pig meat-derived flavoring, which could explain why the black pig meat-derived flavoring had stronger meaty aroma than the black pig meat-derived flavoring.
