Synthesis, characterisation and electrochemical studies of dioxouranium (VI) complexes of dioxolenes with pyridine bases

Mixed ligand complexs of the formulae UO2 (O O) (L-L) (H2O) (2-5) where O O = dioxolenes viz pyrocatechol (2), tert-butylcatechol (3), di-tert-butylcatechol (4) and tetrachlorocatechol (5) and L-L = pyridine (b), bipyridine (c), o-phenanthroline (d) and dipyridylamine (e) have been prepared and characterised by elemental, IR, UV-vis and thermal analyses. Cyclic voltammograms suggest three successive redox responses. The catechol oxidation is highly sensitive to the nature of the substituents. The low energy transition in the visible region is dependent on the nature of the catechol and pyridine base used. This band is assigned to ligand-to-ligand charge transfer (LLCT) transition and is qualitatively assigned as 3b1 (cat) ? pi* (base) transition.

Extended scaffold glucuronides: En route to the universal synthesis of O -aryl glucuronide prodrugs

We demonstrate that an extended scaffold based on a self-immolative linker (SIL) enables the universal production of O-aryl glucuronide prodrugs: high yield glucuronidation is performed on a precursor substrate (SIL) and the subsequent drug conjugation proceeds via less challenging chemical reactions.

Use of a conformational radical clock for evaluating alkyllithium-mediated cyclization reactions

matrix presented The reductive lithiation of nitrile 9 led to the cyclic product 11 as a single diastereomer in 42% ee. The intermediate radical is a conformational radical clock. The radical lifetime can be determined from the optical purity of the product 11. We show that the lifetime of the intermediate radical is too brief to allow a radical cyclization, and thus the cyclization proceeds through an alkyllithium intermediate.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C6H10O3, you can also check out more blogs about51673-83-7

Chemical composition of fennel seed extract and determination of fenchone in commercial formulations by GC?MS method

In the present study, various phytoconstituents of methanolic extract of Foeniculum vulgare were identified using gas-chromatography mass spectrometry (GC?MS) method. GC?MS method was also applied for the analysis of biomarker fenchone in extract and eight different commercial formulations. The mass of prepared extract and formulations A?D and H (commercial herbal mixtures and commercial extract) used for the analysis of fenchone was 10?g. However, the mass of formulations E?G (soft gelatin capsules) was 100?mg. Fifty seven different phytoconstituents were identified in the methanolic extract of F. vulgare using GC?MS technique. The main compounds identified were trans-anethole (31.49%), 2-pentanone (25.01%), fenchone (11.68%) and benzaldehyde-4-methoxy (8.01%). Several other compounds were also identified in higher amounts and some compounds were identified in trace amounts. Many compounds have been reported for the first time in the methanolic extract of F. vulgare. The amount of fenchone was found to be maximum in plant extract (9.789?mg/g) in comparison with other commercial formulations by the proposed GC?MS technique. In three different commercial formulations (F, G and H), the amount of fenchone was obtained as more than 1.0?mg/g. However, in five different commercial formulations (A, B, C, D and E), the amount of fenchone was recorded as less than 0.1?mg/g. This method could be utilized for the analysis of fenchone contents in the commercial formulations containing fenchone as an active ingredient. The results obtained in this work could be useful in standardization of commercial formulations containing fenchone.

Discovery of potent azaindazole leucine-rich repeat kinase 2 (LRRK2) inhibitors possessing a key intramolecular hydrogen bond ? Part 2

The discovery of disease-modifying therapies for Parkinson’s Disease (PD) represents a critical need in neurodegenerative medicine. Genetic mutations in LRRK2 are risk factors for the development of PD, and some of these mutations have been linked to increased LRRK2 kinase activity and neuronal toxicity in cellular and animal models. As such, research towards brain-permeable kinase inhibitors of LRRK2 has received much attention. In the course of a program to identify structurally diverse inhibitors of LRRK2 kinase activity, a 5-azaindazole series was optimized for potency, metabolic stability and brain penetration. A key design element involved the incorporation of an intramolecular hydrogen bond to increase permeability and potency against LRRK2. This communication will outline the structure-activity relationships of this matched pair series including the challenge of obtaining a desirable balance between metabolic stability and brain penetration.

Iron-catalyzed regioselective transfer hydrogenative couplings of unactivated aldehydes with simple alkenes

An FeBr3-catalyzed reductive coupling of various aldehydes with alkenes that proceeds through a direct hydride transfer pathway has been developed. With iPrOH as the hydrogen donor under mild conditions, previously challenging coupling reactions of unactivated alkyl and aryl aldehydes with simple alkenes, such as styrene derivatives and alpha-olefins, proceeded smoothly to furnish a diverse range of functionalized alcohols with complete linear regioselectivity. The reductive coupling of various aldehydes and alkenes through a direct hydride transfer pathway can be catalyzed by FeBr3.

Synthesis and cation complexation properties of new macrolides

The cis-2-alkyl-3-oxy-tetrahydropyran unit as a novel structure for the design and synthesis of a new type of ionophores with C2-symmetry is reported. The synthesis of seven different macrolides and a crown ether and their cation complexation properties were investigated. The X-ray crystal structure of some of the receptors provides valuable information on the preferred conformation of tetrahydropyrans in the solid state that can be related to the cation complexation properties in solution. The kinetic template effect has been proved to be a useful tool to improve the yield and selectivity in the synthesis of macrodiolide 3.
