gamma-Carbolines: A novel class of cannabinoid agonists with high aqueous solubility and restricted CNS penetration

An oral, peripherally restricted CB1/CB2 agonist could provide an interesting approach to treat chronic pain by harnessing the analgesic properties of cannabinoids but without the well-known central side effects. gamma-Carbolines are a novel class of potent mixed CB1/CB2 agonists characterized by attractive physicochemical properties including high aqueous solubility. Optimization of the series has led to the discovery of 29, which has oral activity in a rat inflammatory pain model and limited brain exposure at analgesic doses, consistent with a lower risk of CNS-mediated tolerability issues.

Nickel-Catalyzed Amide Bond Formation from Methyl Esters

Despite being one of the most important and frequently run chemical reactions, the synthesis of amide bonds is accomplished primarily by wasteful methods that proceed by stoichiometric activation of one of the starting materials. We report a nickel-catalyzed procedure that can enable diverse amides to be synthesized from abundant methyl ester starting materials, producing only volatile alcohol as a stoichiometric waste product. In contrast to acid- and base-mediated amidations, the reaction is proposed to proceed by a neutral cross coupling-type mechanism, opening up new opportunities for direct, efficient, chemoselective synthesis.

Characterization of organic matter from natural waters using tetramethylammonium hydroxide thermochemolysis GC-MS

The tetramethylammonium hydroxide (TMAH) thermochemolysis method was recently introduced for the qualitative characterization of organic matter from natural waters (NOM). Such characterizations were usually of a qualitative nature, and any semiquantitative assessments of individual compounds were often achieved by measuring relative areas and assuming unity as a response factor. In this paper we evaluate the quantitative measurement of many identified products characteristic of lignin and NOM using an internal standard approach. The relative standard deviation for most quantified compounds was between 1 and 10%. Four NOM samples, isolated by low-temperature, low-pressure evaporation and freeze-drying, were collected from temperate as well as tropical climates. Large variations were found between samples with respect to the distribution of compounds such as fatty acids, lignin-derived compounds, carbohydrate-derived compounds, and protein-derived compounds. We quantified most lignin-derived and aromatic TMAH products as well as fatty acids (as their methyl esters, FAME) that were found in this set of NOM samples. The contribution of lignin-derived compounds to the total quantified TMAH product distribution in these four samples varied between 21 and 35%. The contribution of FAMEs ranged from 32 to 51% whereas the contribution from non-lignin aromatic compounds was 24-32%. TMAH thermochemolysis potentially provides significant information about NOM sources, compared with other degradative techniques, since both lignin-derived compounds and lipids can be quantitatively and simultaneously investigated.

Identification of aroma compounds in chinese “moutai” and “langjiu” liquors by normal phase liquid chromatography fractionation followed by gas chromatography/olfactometry

The aroma-active compounds in two famous Chinese soy sauce aroma type liquors, Moutai and Langjiu liquors, were investigated in this study. The aroma compounds were isolated using liquid/liquid extraction, and further fractionated into acidic, basic, and neutral fractions. The neural fraction was applied to a normal phase liquid chromatography column and further separated based on their polarity. The aroma compounds of seven fractionations were separately analyzed by GC/Olfactometry (GC/O). A total of 186 aroma-active compounds were identified by GC/O and GC/MS. Among these compounds, ethyl hexanoate, hexanoic acid, 3-methylbutanoic acid, 3-methylbutanol, 2,3,5,6-tetramethylpyrazine, ethyl 2- phenylacetate, 2-phenylethyl acetate, ethyl 3-phenylpropanoate, 4-methylguaiacol, and gamma-decalactone had the highest aroma intensity. Several other basic compounds, including 2,3-dimethyl-5-ethylpyrazine, 2,3,5-trimethyl-6-ethylpyrazine, 2,3,5-trimethylpyrazine, were identified to have high aroma indentify. In addition, vanillin, gamma-heptalactone, gamma-nonalactone, Z-whisky lactone, furaneol, and sotolon, were identified in the liquors. Geosmin was also detected in these two liquors.
