Novel triazolopyridylbenzamides as potent and selective p38alpha inhibitors

A new class of p38alpha inhibitors based on a biaryl-triazolopyridine scaffold was investigated. X-ray crystallographic data of the initial lead compound cocrystallised with p38alpha was crucial in order to uncover a unique binding mode of the inhibitor to the hinge region via a pair of water molecules. Synthesis and SAR was directed towards the improvement of binding affinity, as well as ADME properties for this new class of p38alpha inhibitors and ultimately afforded compounds showing good in vivo efficacy.

You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.40191-32-0, Name is Tetrahydro-2H-pyran-4-carbonyl chloride, molecular formula is C6H9ClO2. In a patent, introducing its new discovery.

Discovery of N-[5-({2-[(cyclopropylcarbonyl)amino]imidazo[1,2-b]pyridazin- 6-yl}oxy)-2-methylphenyl]-1,3-dimethyl-1H-pyrazole-5-carboxamide (TAK-593), a highly potent VEGFR2 kinase inhibitor

Vascular endothelial growth factor (VEGF) plays important roles in tumor angiogenesis, and the inhibition of its signaling pathway is considered an effective therapeutic option for the treatment of cancer. In this study, we describe the design, synthesis, and biological evaluation of 2-acylamino-6-phenoxy-imidazo[1,2-b]pyridazine derivatives. Hybridization of two distinct imidazo[1,2-b]pyridazines 1 and 2, followed by optimization led to the discovery of N-[5-({2-[(cyclopropylcarbonyl)amino]imidazo[1,2-b]pyridazin-6-yl} oxy)-2-methylphenyl]-1,3-dimethyl-1H-pyrazole-5-carboxamide (23a, TAK-593) as a highly potent VEGF receptor 2 kinase inhibitor with an IC50 value of 0.95 nM. The compound 23a strongly suppressed proliferation of VEGF-stimulated human umbilical vein endothelial cells with an IC50 of 0.30 nM. Kinase selectivity profiling revealed that 23a inhibited platelet-derived growth factor receptor kinases as well as VEGF receptor kinases. Oral administration of 23a at 1 mg/kg bid potently inhibited tumor growth in a mouse xenograft model using human lung adenocarcinoma A549 cells (T/C = 8%).

Some mutual interactions between lactones and other aroma constituents of food present in concentrations below their odor threshold

To investigate the contribution of subthreshold aroma constituents to the flavor of food, mutual interaction between saturated gamma- And delta lactones (C6- C1 2) and some minor odorants found in various food materials was investigated by sensory evaluation. By the triangle test, the detection odor threshold value of the mixture of (E)-2-hexenyl hexanoate and each of 4-octanolide, 5-hexanolide, 5-nonanolide and 5- decanolide at the ratio of 90:10 decreased significantly from 1 ppm to 0.1 ppm. The (Z)-3-hexenol and the mixture of (Z)-3- hexenol and saturated gamma and delta lactones (C6- C1 2) were evaluated by the same method. The odor intensity of the mixture of (Z)-3-hexenol and each of the following eight lactones such as 4- And 5-hexanolide, 4-octanolide, 4- And 5- nonanolides, 5-decanolide, and 4- And 5-undecanolides present in each concentration below their odor threshold was enhanced significantly. In addition, the odor intensity was enhanced significantly in the mixture of d-limonene + 4-hexanolide, vanillin + 5-hexanolide, and citronellol + both 4-, and 5- hexanolides. The effect of addition of 4-hexanolide on selfadaptation in concentration below its odor threshold to the model solution of some supra-threshold odorants was also studied. The presence of 4-hexanolide in the (E)-2-hexenyl hexanoate and (Z)-3-hexenoI suppressed self-adaptation and the prolongation of the odor sensation by mutural interaction between two odorants was indicated.

Heterogeneous ceria catalyst with water-tolerant Lewis acidic sites for one-pot synthesis of 1,3-diols via prins condensation and hydrolysis reactions

The use of a heterogeneous Lewis acid catalyst, which is insoluble and easily separable during the reaction, is a promising option for hydrolysis reactions from both environmental and practical viewpoints. In this study, ceria showed excellent catalytic activity in the hydrolysis of 4-methyl-1,3-dioxane to 1,3-butanediol in 95% yield and in the one-pot synthesis of 1,3-butanediol from propylene and formaldehyde via Prins condensation and hydrolysis reactions in an overall yield of 60%. In-depth investigations revealed that ceria is a water-tolerant Lewis acid catalyst, which has seldom been reported previously. The ceria catalysts showed rather unusual high activity in hydrolysis, with a turnover number (TON) of 260, which is rather high for bulk oxide catalysts, whose TONs are usually less than 100. Our conclusion that ceria functions as a Lewis acid catalyst in hydrolysis reactions is firmly supported by thorough characterizations with IR and Raman spectroscopy, acidity measurements with IR and 31P magic-angle-spinning NMR spectroscopy, Na+/H + exchange tests, analyses using the in situ active-site capping method, and isotope-labeling studies. A relationship between surface vacancy sites and catalytic activity has been established. CeO2(111) has been confirmed to be the catalytically active crystalline facet for hydrolysis. Water has been found to be associatively adsorbed on oxygen vacancy sites with medium strength, which does not lead to water dissociation to form stable hydroxides. This explains why the ceria catalyst is water-tolerant.
