Hit-to-Lead Optimization of Benzoxazepinoindazoles As Human African Trypanosomiasis Therapeutics

Human African trypanosomiasis (HAT) is a neglected tropical disease caused by infection with either of two subspecies of the parasite Trypanosoma brucei. Due to a lack of economic incentive to develop new drugs, current treatments have severe limitations in terms of safety, efficacy, and ease of administration. In an effort to develop new HAT therapeutics, we report the structure-activity relationships around T. brucei for a series of benzoxazepinoindazoles previously identified through a high-throughput screen of human kinase inhibitors, and the subsequent in vivo experiments for HAT. We identified compound 18, which showed an improved kinase selectivity profile and acceptable pharmacokinetic parameters, as a promising lead. Although treatment with 18 cured 60% of mice in a systemic model of HAT, the compound was unable to clear parasitemia in a CNS model of the disease. We also report the results of cross-screening these compounds against T. cruzi, L. donovani, and S. mansoni.

Comprehensive two-dimensional gas chromatography with mass spectrometry applied to the analysis of volatiles in artichoke (Cynara scolymus L.) leaves

Artichoke (. Cynara scolymus L.) is well known due to its medicinal properties and, as a result, a large number of studies have been conducted to determine the chemical constituents produced by the plant. However, investigations were mainly focused on the non-volatile compounds, while the volatile constituents remained largely neglected. This study was aimed at obtaining a deeper understanding of the volatile composition of artichoke. For this propose, comprehensive two-dimensional gas chromatography coupled to a rapid scanning quadrupole mass spectrometer (GC. ¡Á. GC/qMS) and retention indices were used to improve the chemical characterization of volatiles from leaves. A total of 130 compounds were found, 109 of which are reported for the first time in C. scolymus L., including oxygenated monoterpenes, sesquiterpenes, oxygenated sesquiterpenes, norisoprenoids, lactones, alcohols, ketones and aldehydes. The major compounds were 1-octen-3-one (3.85%), (. E)-2-hexenal (3.75%), benzene acetaldehyde (2.90%), 2,2-dimethyl-4-pentenal (2.81%), beta-ionone (1.94%), furfural (1.65%), (. E)-beta-damescenone (1.59%), alpha-methyl-gamma-butirolactone (1.53%), benzaldehyde (1.47%) and dihydroactinidiolide (1.44%). The comprehensive GC. ¡Á. GC/qMS approach enabled a greater number of analytes to be identified, approximately four times higher than that obtained for GC/qMS. Additionally, the results imply that artichoke leaves are a potential source of volatile bioactive compounds.

Resolution of certain asymmetric primary amines using lasalocid

Racemic modifications of optically active primary or tertiary amines are treated with lasalocid to form diastereomeric salts. The so-formed diastereomeric salts are separated and, subsequently, can be chemically decomposed to give the desired enantiomers of the amine. The resolving agent, lasalocid, is recovered in this process by precipitation or evaporation from organic solvents.

Revised stereochemistry of ceramide-trafficking inhibitor HPA-12 by X-ray crystallography analysis

In response to Berkes’s report revising the stereochemistry of HPA-12, an important ceramide-trafficking inhibitor that was discovered and synthesized and its stereochemistry determined in 2001, the synthesis and the stereochemistry were reinvestigated. A large-scale synthetic method for HPA-12 based on a Zn-catalyzed asymmetric Mannich-type reaction in water was developed. Single crystals of HPA-12 for X-ray crystallographic analysis were obtained from ethyl propionate/n-hexane, and the stereochemistry was definitely determined to be 1R,3S, consistent with Berkes’s revised structure.

Characterization of odorants in waxes for hot melt adhesives using sensory and instrumental analyses

Waxes are important additives in hot melt adhesives for improving the properties of the final product such as the melting point or viscosity. Up to one third of the formulation of the final product consists of waxes. For this purpose usually polyethylene (PE) waxes or Fischer-Tropsch (FT) waxes are used. Waxes affect the overall smell of hot melt adhesives, and often in a negative way. In our study the overall odor of five different waxes made by different manufacturing methods was characterized in order to classify the samples according to their overall smell. First of all the samples were evaluated by a trained sensory panel at room temperature and after heating to 80 C using descriptive analyses. Then the volatiles responsible for the overall smell of the samples were directly extracted using thermal desorption in combination with cryo-focusing and analyzed by gas chromatography-mass spectrometry-olfactometry (GC-MS/O). Moreover, the volatiles in the waxes were recovered using solvent extraction and isolated by solvent assisted flavour evaporation (SAFE). The most dominant odorants were then characterized by GC-O and odor extract dilution analysis (OEDA). Using these approaches 39 odorants having different chemical structures were successfully identified for the first time in waxes used as additives in hot melt adhesives. These odorants included alcohols with tallowy, soapy odor qualities such as 2-methyl-2-decanol, 2-methyl-2-dodecanol, and 1-undecanol, as well as a range of lactones such as gamma-decalactone and gamma-undecalactone having soapy, peach-like odor descriptions. The attributes of the odorants detected using GC analyses correlated with the descriptive analyses of the human sensory panel. This study indicates that the odor impact of waxes to hot melt adhesives depends on the manufacturing method of each single wax and that there is no clear trend for the preferential usage of PE or FT waxes.
