Formamides as Lewis Base Catalysts in SNReactions?Efficient Transformation of Alcohols into Chlorides, Amines, and Ethers

A simple formamide catalyst facilitates the efficient transformation of alcohols into alkyl chlorides with benzoyl chloride as the sole reagent. These nucleophilic substitutions proceed through iminium-activated alcohols as intermediates. The novel method, which can be even performed under solvent-free conditions, is distinguished by an excellent functional group tolerance, scalability (>100 g) and waste-balance (E-factor down to 2). Chiral substrates are converted with excellent levels of stereochemical inversion (99 %??95 % ee). In a practical one-pot procedure, the primary formed chlorides can be further transformed into amines, azides, ethers, sulfides, and nitriles. The value of the method was demonstrated in straightforward syntheses of the drugs rac-Clopidogrel and S-Fendiline.

Synthesis and antibacterial in vitro activity of novel analogues of nematophin

The synthesis and in vitro antibacterial activity of new derivatives and analogues of nematophin are described. It was shown that the unsubstituted amide NH-group is essential for bioactivity. Alkyl- or aryl-substitution at the 1-position results in a distinct increase of antibacterial activity. Addition of protein (blood or serum) to the culture media reduces the inhibitory activity on bacteria.

Antibacterial activity of endophytic actinomycetes isolated from the medicinal plant Vochysia divergens (Pantanal, Brazil)

Endophytic actinomycetes from medicinal plants produce a wide diversity of secondary metabolites (SM). However, to date, the knowledge about endophytes from Brazil remains scarce. Thus, we analyzed the antimicrobial potential of 10 actinomycetes isolated from the medicinal plant Vochysia divergens located in the Pantanal sul-mato-grossense, an unexplored wetland in Brazil. Strainswere classified as belonging to the Aeromicrobium, Actinomadura, Microbacterium, Microbispora, Micrococcus, Sphaerisporangium, Streptomyces, and Williamsia genera, through morphological and 16S rRNA phylogenetic analyzes. A susceptibility analysis demonstrated that the strains were largely resistant to the antibiotics oxacillin and nalidixic acid. Additionally, different culture media (SG and R5A), and temperatures (28 and 36C) were evaluated to select the best culture conditions to produce the active SM. All conditions were analyzed for active metabolites, and the best antibacterial activity was observed from metabolites produced with SG medium at 36C. The LGMB491 (close related to Aeromicrobium ponti) extract showed the highest activity against methicillin-resistant Staphylococcus aureus (MRSA), with a MIC of 0.04 mg/mL, and it was selected for SM identification. Strain LGMB491 produced 1-acetyl-beta-carboline (1), indole-3-carbaldehyde (2), 3-(hydroxyacetyl)-indole (4), brevianamide F (5), and cyclo-(L-Pro-L-Phe) (6) as major compounds with antibacterial activity. In this study, we add to the knowledge about the endophytic community from the medicinal plant V. divergens and report the isolation of rare actinomycetes that produce highly active metabolites.

P450-Mediated Coupling of Indole Fragments To Forge Communesin and Unnatural Isomers

Dimeric indole alkaloids are structurally diverse natural products that have attracted significant attention from the synthetic and biosynthetic communities. Here, we describe the characterization of a P450 monooxygenase CnsC from Penicillium that catalyzes the heterodimeric coupling between two different indole moieties, tryptamine and aurantioclavine, to construct vicinal quaternary stereocenters and yield the heptacyclic communesin scaffold. We show, via biochemical characterization, substrate analogues, and computational methods that CnsC catalyzes the C3-C3′ carbon-carbon bond formation and controls the regioselectivities of the pair of subsequent aminal bond formations to yield the communesin core. Use of omega-N-methyltryptamine and tryptophol in place of tryptamine led to the enzymatic synthesis of isocommunesin compounds, which have not been isolated to date.

Addition of protease during starch liquefaction affects free amino nitrogen, fusel alcohols and ethanol production of fermented maize and whole and decorticated sorghum mashes

The aim of this research was to study the effect of the dual treatment of sorghum decortication and protease addition during liquefaction with alpha-amylase, on the concentration of free amino nitrogen (FAN), fusel alcohols and ethanol during yeast fermentation. A bifactorial experiment was designed to revise the differences among grains (maize, whole and 9.7% decorticated sorghum) and the effectiveness of protease addition during liquefaction. The decorticated sorghum was more susceptible to protein hydrolysis compared to the whole kernel sorghum due to its lower fiber content. The protease improved the levels of FAN approximately to 60% and 30% in the maize and sorghum mashes, respectively. The maize mash contained the highest amount of FAN followed by the decorticated and whole sorghum mashes. The protease treatment improved the fusel alcohol concentration in both sorghum beers and did not affect ethanol concentration in the maize mash. Both sorghum decortication and protease addition during liquefaction are therefore recommended treatments to obtain mashes with a higher FAN level. The decorticated protease-treated sorghum mashes yielded higher amounts of ethanol compared to the maize treatments and produced the maximum ethanol after only 20. h of fermentation. This research proved that a positive synergistic effect on FAN concentration, fusel alcohols and bioethanol yields can be achieved through the proposed proceeding of sorghum decortication and protease addition.

sigma Ligands with subnanomolar affinity and preference for the sigma2 binding site. 1. 3-(omega-Aminoalkyl)-1H-indoles

A series of 4-(1H-indol-3-yl)-1-butyl-substituted 4-phenylpiperidines, 4- phenyl-1,2,3,6-terrahydropyridines, and 4-phenylpiperazines was synthesized. The phenyl group was optionally substituted with 4-fluoro or 2-methoxy substituents. High affinity for both sigma1 and sigma1 binding sites was achieved with these compounds. Additionally, these compounds had relatively high affinity for serotonin 5-HT(1A) and 5-HT(2A), dopamine D2, and adrenergic alpha1 receptors. Introduction of a 4-fluorophenyl substituent at the indole nitrogen atom rendered very selective sigma2 ligands with subnanomolar affinity for the sigma2 binding site. The prototype of such a compound was 1-(4- fluorophenyl)-3-[4-[4-(4-fluorophenyl)-1-piperidinyl]-1-butyl]-1H-indole, 11a (code no. Lu 29-253). This compound had the following binding affinities: IC50 (sigma1) = 16 nM, IC50 (sigma2) = 0.27 riM, IC50 (5-HT(1A)) = 22 000 nM, IC50 (5-HT(2A)) = 270 nM, IC50 (D2) = 4200 nM, IC50 (alpha1) = 220nM. Spiro-joining of the phenyl and the piperidine rings into a spiro[isobenzofuran-1(3H),4′-piperidinel ring system resulted in even more selective compounds. Variations of the 1-substituent at the indole and of the chain length of the alkylene spacer group were studied. The optimal compound was the spiro analogue of compound 11a. This compound is 1′-14-[1(4- fluorophenyl)-1H-indol-3-yl]-1-butyl]spiro[isobenzofuran-1(3H),4′- piperidine], 14f (code no. Lu 28-179), with the binding affinities: IC50 (sigma1) = 17 nM, IC50 (sigma2) = 0.12 nM, IC50 (5-HT(1A)) = 21 000 nM, IC50 (5-HT(2A)) = 2000 nM, IC50 (D2) = 800 nM, IC50 (alpha1) = 330 nM. However, the most selective sigma2 versus sigma1 ligand was the tropane derivative 1-(4-fluorophenyl)-3-[4-[3-(4-fluorophenyl)-8- azabicyclo[3.2.1]oct-2-en-8-yl]-1-butyl]-1H-indole, 15a. This compound had the following binding affinities: IC50 (sigma1) = 1200 nM, IC50 (sigma2) = 2.5 nM. Potent anxiolytic activity in the black/white box exploration test in rats was found with the two most prominent sigma2 ligands Lu 29-253 and Lu 28- 179. Good penetration into the CNS was documented both after subcutaneous and peroral administration of Lu 28-179 by ex vivo binding studies. Long duration of action was demonstrated both in ex vivo binding (T(1/2) ~ 20 h) and in the black/white box exploration test.

A novel series of thromboxane A2 synthetase inhibitors with free radical scavenging and anti-peroxidative activities

A novel series of indoline derivatives with imidazole and carboxyl moieties were synthesized and evaluated for their thromboxane A2 (TXA2) synthetase inhibiting, radical scavenging and anti-peroxidative activities. Among the compounds synthesized, 3.{5-substituted-3-[2-(imidazol-1-yl)ethyl]indolin-1-yl}propionic acids showed free radical scavenging activity and inhibitory effects on lipid-peroxidation of rat brain homogenate and on arachidonate-induced TXA2-dependent aggregation of rabbit platelets. The anti-platelet and anti-peroxidative activities were related to the lipophilicity of the 5-substituent. The 5-hexyloxy derivative (13) showed about 35-fold higher inhibitory activity on TXA2 synthesis than that of ozagrel and about 100-fold higher activity on lipid peroxidation than that of alpha-tocopherol. Compound 13 showed in vivo anti-thrombotic effect in mice and ex vivo anti-peroxidative activity in rats.

Molecularly imprinted solid phase extraction in an efficient analytical protocol for indole-3-methanol determination in artificial gastric juice

In this study we presented a new and efficient analytical protocol for determination of indole-3-methanol (indole-3-carbinol, I3C) in spiked artificial gastric juice used as a model sample. The analytical protocol involves separation of I3C on the imprinted stationary phase as well as the analysis of I3C using high performance liquid chromatography coupled with UV detection. The described analytical protocol allows selective isolation of I3C present in a complex matrix (such as inorganic salts and protein) from the mixture of I3C metabolites formed in artificial gastric juice with high total recovery equal to 96 ¡À 3% in a low concentration range of 0.125-10 mumol L-1. The limit of detection and limit of quantification were 0.150 and 0.454 mumol L-1, respectively. The efficacy of the analytical protocol was demonstrated by the results obtained for non-imprinted commercial sorbents C18, Florisil, and MCX Oasis used in the separation step. The affinity of the imprinted polymer matrix was tested by non-competitive binding experiments of four structurally related analytes. The template behavior was analyzed during the imprinting process.

Resonant Two-Photon Ionization Spectroscopic Analysis of Indole and Catechol Derivatives Using Pulsed Laser Desorption with Entrainment into Supersonic Jet Expansions

Pulsed laser desorption is used as a means of volatilizing thermally labile indole and catechol derivatives for entrainment into a supersonic jet expansion.The jet expansion provides ultracold molecules whose sharp spectral features are probed by resonant two-photon ionization (R2PI) spectroscopy in a time-of-flight mass spectrometer.Despite the structural similarity between many of the compounds studied herein, R2PI electronic spectrometry is shown to be a sensitive probe of small structural changes in these molecules and thus as a means of uniquely identifying each of these species.Target mixtures of various indole based compounds are studied under different conditions in order to establish the limitations to the selectivity of this technique.In addition, the limits of sensitivity are in the 10 pg range for these compounds and an optical spectrum can be obtained with as little as 300 ng of sample.
