Dearomatization of Indoles via a Phenol-Directed Vanadium- Catalyzed Asymmetric Epoxidation and Ring-Opening Cascade

An enantioselective dearomatization of indole derivatives was realized by the complexes derived from the vanadium complex VO(acac)2 and C2-symmetric bis-hydroxamic acid (BHA) ligands. The reaction proceeded via asymmetric epoxidation and ring-opening by the linked phenol cascade, affording 5a,6,10b,11-tetrahydrochromeno[2,3-b]indol-10b-ol derivatives in up to 83% yield and 98% ee under mild reaction conditions.

Development of potent inhibitors of pyocyanin production in pseudomonas aeruginosa

The development of new approaches for the treatment of antimicrobial-resistant infections is an urgent public health priority. The Pseudomonas aeruginosa pathogen, in particular, is a leading source of infection in hospital settings, with few available treatment options. In the context of an effort to develop antivirulence strategies to combat bacterial infection, we identified a series of highly effective small molecules that inhibit the production of pyocyanin, a redox-active virulence factor produced by P. aeruginosa. Interestingly, these new antagonists appear to suppress P. aeruginosa virulence factor production through a pathway that is independent of LasR and RhlR.

Development of a high-throughput screening analysis for 288 drugs and poisons in human blood using Orbitrap technology with gas chromatography-high resolution accurate mass spectrometry

The screening analysis for drugs and poisons always symbolizes the capabilities of a forensic laboratory. Due to the rapid emergence of new compounds in clinical and forensic intoxication cases, sensitive and specific methods are necessary for the screening of wide range of target compounds. A novel high-throughput screening method has been developed for the toxicological analysis of 288 drugs and poisons in human blood using Orbitrap technology with gas chromatography-high resolution mass spectrometry (GC-HRMS). This method allows for the fast detection and identification of high-throughput forensically important drugs and poisons, e.g., drugs of abuse (cocaine, amphetamines, synthetic cannabinoids, opiates, hallucinogen), sedative-hypnotics, antidepressants, non-steroidal anti-inflammatory drugs, pesticides (acaricides, fungicides, insecticides, nematicides), and cardiovascular agents in one single GC-Q Exactive run. After a simple extraction with ethyl ether and buffer, following centrifugation, the supernatant was injected into the system. For detection, spiked blood samples were analyzed by Orbitrap-GC-HRMS using an electrospray ionization in full scan mode with a scan range from 40 to 650 (m/z). The identification of drugs and poisons in the samples was carried out by searching the accurate molecular mass of characteristic fragment ions, ion rations and retention time (RT) against the in-house library that we developed with 70 ev electron energy. The limit of detection (LOD) for most compounds (249 in a total of 288 compounds) was below 100 ng/mL. For selectivity, no substances have been identified in drug-free blood samples from six different sources, and the method was suitable for the recovery and the carryover. The coefficient of variation (CV) of the RTs was below 0.99% in all reproducibility experiments. Mass accuracy was always better than 3 ppm, corresponding to a maximum mass error of 1.04 millimass units (mmu). The developed method was applied to 136 real samples from forensic cases, demonstrating its suitability for the sensitive and fast screening of high-throughput drugs in human blood samples.

Palladium acetate assisted synthesis of five-membered N-polyheterocycles

The metal-assisted synthesis of heterocyclic compounds is known to be one of the extremely developing as well as significant concepts of organic chemistry. Because of their expensive, complex working of the instrument and difficult procedures, the methodologies used earlier for the heterocycle synthesis were less amicable to the researchers. The Pd(OAc)2-mediated cyclic reactions have been recognized to be very effective for both the stereoselective as well as regioselective formation of the 5-membered N-bearing heterocyclic compounds. The different uses of palladium acetate, as a catalyst in the formation of 5-membered N-containing polyheterocycles, are covered in this review article.

Color measurement of the animal integument predicts the content of specific melanin forms

The appearance of animals largely depends on melanins present in their integument. However, it is unclear how different melanin forms create different animal color phenotypes. We used reflectance spectrophotometry to measure the color expression of feathers and hairs of 59 species of birds and 12 species of mammals, comprising a significant part of the palette of melanin-based colors, and analyzed for the first time the detailed chemical composition of melanins in the same samples by HPLC. We quantified color variation by means of the slope of percent reflectance regressed against wavelength, as this was the best predictor of a human categorization of color phenotype, increasing with the following scale: black, grey, dark brown, dark orange, light brown and light orange. Color slope variation was explained by levels of the 5,6-dihydroxyindole-2-carboxylic acid (DHICA) unit of eumelanin and the benzothiazole moiety of pheomelanin in feathers and hairs, but not by levels of the 5,6-dihydroxyindole (DHI) unit of eumelanin nor the benzothiazine moiety of pheomelanin. DHICA-eumelanin and benzothiazole-pheomelanin components explained color expression in opposite ways, decreasing and increasing, respectively, with color slope. Color slope, and also color categorization as perceived by humans, can therefore be used to infer the melanin chemical composition of feathers and hairs. Given that cytotoxic reactive oxygen species (ROS) are more abundantly formed during the synthesis of DHI than during the synthesis of DHICA in eumelanins, and in pheomelanins with higher benzothiazine/benzothiazole ratios, melanin-based colors interestingly reflect the content of the less pro-oxidant melanin forms.

Synthesis and Characterization of Pd Schiff Base Complex Immobilized onto Functionalized Nanoporous MCM-41 and its Catalytic Efficacy in the Suzuki, Heck and Stille Coupling Reactions

Abstract: The present work describes the use of palladium-vanillin-Schiff-base complex immobilized on MCM-41 nanostructure as efficient catalyst for the Suzuki?Miyaura, Stille and Mizoroki?Heck reactions of several aryl halides under aerobic conditions. All the reactions were carried out in green solvents (H2O and PEG-400). The developed procedure results bring several benefits such as uses of inexpensive and non-toxic ligand (vanillin), easy catalyst/product separation and catalyst recycling. The catalyst can be reused at least for five consecutive cycles without a significant loss of its catalytic activity or metal leaching. Graphical Abstract: [Figure not available: see fulltext.].
