Rauvolfia vomitoria is widely distributed in the tropical regions of Africa and Asia, and has been used in traditional folk medicine in China. Indole alkaloids were found to be major bioactive components, while the effects of diabetes mellitus on the pharmacokinetic parameters of the components have not been reflected in vivo. In this study, an efficient and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous determination of five ingredients of R. vomitoria in rats. Detection was implemented in multiple-reaction-monitoring mode with an electrospray positive-ionization source. Validation parameters were all in accordance with the current criterion. The established method was effectively employed to compare the pharmacokinetic behaviors of five alkaloids (reserpine, yohimbine, ajmaline, ajmalicine, and serpentine) between normal and type 2 diabetic rats. The single-dose pharmacokinetic parameters of the five alkaloids were determined in normal and diabetic rats after oral administration of 100 and 200 mg/kg body weight. The results indicated that diabetes mellitus significantly altered the pharmacokinetic characteristics of yohimbine, ajmaline, and ajmalicine after oral administration in rats. This is an attempt to provide some evidence for clinicians that may serve as a guide for the use of antidiabetic medicine in clinical practice.

The first TfOH-catalyzed three-component Friedel-Crafts alkylation/ketalization sequence of indoles, alcohols and ortho-hydroxychalcones was developed to afford a wide range of 4-indole substituted chromans bearing a ketal motif in 77-99% yields. Notably, only a simple filtration was needed to purify them. By altering methanol to CHCl3, 2,4-bisindole substituted chroman with the same indole substituent at the C2 and C4 positions was afforded. Moreover, 2,4-bisindole substituted chromans with different indole substituents could be obtained by treatment of 4-indole monosubstituted chromans with another indole molecule.

An organocatalysis triggered highly regio- and stereoselective two-step sequence between hemiacetals and indole-containing nitroolefins was developed. The key to the success of this sequence was the intramolecular oxocarbenium ion induced collective alkylation at the C3, C2, or N1-position of the indole moiety, respectively, providing biologically important polycyclic indole derivatives with different ring connectivities. An unexpected epimerization was observed during the C3-alkylation process, which generated products with different relative configurations compared with the C2- and N1-alkylation products.

BACKGROUND: Currently, several indole markers are measured separately to support diagnosis and follow-up of patients with neuroendocrine tumors (NETs). We have developed a sensitive mass spectrometry method that simultaneously quantifies all relevant tryptophan-related indoles (tryptophan, 5-hydroxyayptophan, serotonin, 5-hydroxyindoleacetic acid) in platelet-rich plasma. Direct-matrix derivatization was used to make the chemical properties of the indoles uniform and to improve the analytical sensitivity and specificity of the assay. METHODS: In situ derivatization was performed directly in platelet-rich plasma with propionic anhydride at an ambient temperature. The derivatized indoles were extracted by online solid-phase extraction and eluted to the analytical column for separation followed by mass spectrometric detection. The method was validated according to international guidelines. Platelet-rich plasma samples from 68 healthy individuals and 40 NET patients were analyzed for tryptophan, 5-hydroxytryptophan, serotonin, and 5-hydroxyindoleacetic acid. RESULTS: The method reproducibly quantified relevant indoles in 8.5 min, including online sample cleanup. Intra- and interassay imprecision, evaluated at 3 different concentrations, ranged from 2.0% to 12% and 1.9% to 13%, respectively. The limit of quantification was sufficient to measure endogenous concentrations of all 4 indoles. Healthy individuals and NET patients had different concentrations of 5-hydroxytryptophan, serotonin, and 5-hydroxyindoleacetic acid, but tryptophan concentrations were the same. CONCLUSIONS: Direct-matrix derivatization in combination with LC-MS/MS is a powerful tool for the simultaneous quantification of all tryptophan-related indoles in platelet-rich plasma. Simultaneous profiling of relevant indoles improves the biochemical characterization and follow-up of NETs. (C) 2019 American Association for Clinical Chemistry

Malaria, caused by the genusPlasmodium, remains a global public health concern. It is estimated by the World Health Organization that over 40% of the world’s population lives in areas at risk for malarial transmission, and around half a million people succumb to this infectious disease annually, which is related to the rapid spread of drug-resistant parasite strains. Indole derivatives, which possess broad-spectrum pharmacological properties, play a crucial role in the discovery of new drugs. Many indole derivatives exhibited potential in vitro and in vivo activity against both drug-sensitive and drug-resistant malaria, suggesting that the indole moiety is a useful template for the development of novel antimalarial agents. This review outlines the advances in indole alkaloids and hybrids with antimalarial potential in the recent decade.

This method is selective at the C3 position of indoles and offers several advantages such as broad substrate scope, functional group tolerance (bromo, carboxylic acid, methoxy, difluoromethoxy, ester groups) and gives the required products in good to excellent yields. The experimental simplicity makes it a useful and attractive approach for the synthesis of 3-arylsulfenylindoles. The compounds 1-12 are evaluated for the anti-bacterial agents.

The addition of electron-deficient radicals to theC2position of indoles has been described in the literature as opposed to electrophilic addition at theC3 position. Density functional theory calculations were used to understand the switch in regioselectivity fromC3toC2for indole to undergo radical additions. Electron deficient radicals have a lower barrier for the reaction atC2 and a lower energy radical intermediate that benefits from benzylic radical stabilization. Trifluoromethyl radical addition has a lower energy barrier than acetonitrile radical, and theC3 addition transition state is just 0.8 kcal/mol higher thanC2. This is supported by experimental observations.
