Dual serotonin transporter/histamine H3 ligands: Optimization of the H3 pharmacophore

A series of tetrahydroisoquinolines acting as dual histamine H3/serotonin transporter ligands is described. A highly regio-selective synthesis of the tetrahydroisoquinoline core involving acid mediated ring-closure of an acetophenone intermediate followed by reduction with NaCNBH3 was developed. In vitro and in vivo data are discussed.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 21987-29-1 is helpful to your research. category: piperidines

Studies on pyrazine derivatives, XLVI: The synthesis of new pyrazine derivatives with N?-(pyrazine-2-carbonyl)-hydrazinecarbodithioic acid methyl ester usage

4-Omega-alkylsubstituted derivatives of 1,2,4-triazole-2-thiones 2-7 were obtained using the high reactivity of N?-(pyrazine-2-carbonyl)- hydrazinecarbodithioic acid methyl ester 1 towards amines. In the reaction with cysteamine 1,3-thiazaethylene-1,2,4-triazole 8 formed. Aromatic amines and N-aminocycloalkylamines gave thiosemicarbazide derivatives 9-12 under the same conditions. The solution of sodium hydroxide caused the decomposition of compounds 11 and 12 and resulted in 4-piperidino- and 4-morpholino- thiosemicarbazides 13 and 14. Compounds 11 and 12 were cyclized to appropriate 4-substituted 1,2,4-triazole-2-thiones 16 and 17 under the influence of DBU or potassium carbonate solution. The heating of derivative 12 with sulfuric acid led to disubstituted 1,3,4-thiadiazole 18. Copyright Taylor & Francis Group, LLC.

Study of thermal maturation processes of sulfur-rich source rock using compound specific sulfur isotope analysis

Semi-open pyrolysis experiments were conducted on a thermally immature, organic and sulfur-rich source rock (Ghareb Formation, Israel). Structural and sulfur isotope ratio (34S/32S) changes in specific organic sulfur compounds were studied along with bulk sulfur phases (H2S, kerogen, oil) during thermal maturation and oil formation. Oil, gas and rock samples were collected sequentially at several points along the maturation path and were analyzed. In addition, four natural crude oils from Israel were analyzed and the results were compared to the pyrolytic oils. The results showed relatively large delta34S variability (?10?) of the organic sulfur compounds (OSCs) in the bitumen of the unheated rock and first pyrolytic oil. This variability was probably a remnant of the original sulfur isotopic signature acquired during the sulfurization of the organic matter in the early diagenetic process. At later stages of thermal maturation, the variability of the sulfur isotopic values in the kerogen gradually decreased to ?2?. Three mechanisms were suggested to explain the structural changes and isotopic fractionations of OSCs in the kerogen and generated oils: (A) Cleavage of weak S?S and C?S bonds leading to the release of large amounts of H2S and to cyclization of the precursors in the kerogen with small fractionations. Thus, the OSCs released by this mechanism preserved their distinct delta34S values. (B) Re-reaction of the released S species with hydrocarbons and generation of new OSCs within the kerogen (or bitumen) matrix. (C) Cleavage of stronger C?C bonds and transformation of OSCs to create more stable compounds (e.g. dibenzothiophenes) from multiple sulfur sources. Mechanisms (B) and (C) homogenized the delta34S values of the different OSCs which reflected that of the bulk kerogen. The bulk organic sulfur phases (bitumen, oil, kerogen) were 34S enriched by < 1? despite large amounts of 34S-depleted H2S (53% of total S) that was released continuously (?open system?). Therefore, the preferential loss of H2S during thermal maturation may not be responsible to the 34S enrichment of oils as reported in some petroleum basins. The overall outcome of the maturation process yields OSCs with delta34S values that closely reflect the kerogen and can be used as a fingerprint for oil-oil and oil-source rock correlation over wide ranges of thermal maturity. The applicability of such correlation is demonstrated by the very good correlation of delta34S values of specific OSCs between artificial and natural oil samples. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Selection, synthesis, and structure-activity relationship of tetrahydropyrido[4,3-d]pyrimidine-2,4-diones as human GnRH receptor antagonists

The present article describes a selection of a new class of small molecule antagonists for the h-GnRH receptor, their preparation, and evaluation in vitro. Three computational methods were combined into a consensus score, to rank order virtual templates. The top 5% of templates were further evaluated in silico and assessed for novelty and synthetic accessibility. The tetrahydropyrido[4,3-d]pyrimidine-2,4-dione core was selected for synthesis and evaluated in vitro. Using an array approach for analog design and synthesis, we were able to drive the binding below 10 nM for the h-GnRH receptor after two rounds of optimization.
