The invention provides a method for detection of active form of analytes in a sample and/or for determination of ability of tested substances to bind to the active site of these analytes, comprising the following steps: a) analyte or group of analytes from the sample is immobilized on the surface of a solid carrier either by non-specific non-covalent adsorption or by covalent binding of surface functional groups of the analyte and corresponding functional groups of the solid carrier, or preferably via a binding molecule which is bound to the surface of the solid carrier before immobilization of the analyte or group of analytes and is capable of selectively binding the analyte or group of analytes contained in the sample during incubation of the solid carrier with the sample; b) analyte or group of analytes is incubated with a detection probe which binds selectively to the analyte or group of analytes via a compound for selective binding to the analyte active site; whereas the probe consists of a low molecular compound for selective binding to the analyte active site; an oligonucleotide tag, optionally with a covalently attached fluorophore, biotin or a chemical group, and a chemical linker covalently linking the compound for selective binding to the analyte active site and the oligonucleotide tag; c) then the solid carrier is washed to remove unbound detection probe; and subsequently, the amount of bound detection probe is determined, whereas this amount is directly proportional to the amount of the analyte or group of analytes in the sample. The described method has broad application in medicine. Given the exceptional sensitivity of only a few dozen molecules, it provides the ability to determine the protein markers in blood in a concentration yet undetectable.

A document type is Article, introducing its new discovery., Application In Synthesis of 6-Fluorobenzo[d]thiazol-2-amine

There is an urgent need for structurally novel anti-norovirus agents. In this study, we describe the synthesis, anti-norovirus activity, and structure-activity relationship (SAR) of a series of heterocyclic carboxamide derivatives. Heterocyclic carboxamide 1 (50% effective concentration (EC50)=37 muM) was identified by our screening campaign using the cytopathic effect reduction assay. Initial SAR studies suggested the importance of halogen substituents on the heterocyclic scaffold and identified 3,5-di-boromo-thiophene derivative 2j (EC50=24 muM) and 4,6-di-fluoro-benzothiazole derivative 3j (EC50=5.6 muM) as more potent inhibitors than 1. Moreover, their hybrid compound, 3,5-di-bromo-thiophen-4,6-di-fluoro-benzothiazole 4b, showed the most potent anti-norovirus activity with a EC50 value of 0.53 muM (70-fold more potent than 1). Further investigation suggested that 4b might inhibit intracellular viral replication or the late stage of viral infection.

A novel oxidative C-S bond cleavage reaction of DMSO for dual C-C and C-N bond formation is described. A series of acetyl heteroarenes could be selectively converted into the corresponding beta-amino ketones, which are frequently found in biologically active compounds and pharmaceuticals. DMSO acted in this reaction not only as the solvent but also as a one-carbon bridge.

Manganese dioxide nanostructures were coated on natural silk (MnO2@silk) by simple immersion of the silk fibers into a KMnO4 aqueous solution. The silk was found to act as a in situ reducing agent and substrate in aqueous KMnO4 solution for the heterogeneous production of MnO2 nanostructures. The structure of synthesized catalyst was characterized by X-ray diffraction (XRD), flame atomic absorption spectroscopy (FAAS), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) analysis. The catalytic activity of the MnO2@silk was examined in the aerobic oxidation of alkyl arenes, alcohols, and oximes to their corresponding carbonyl compounds and a one-pot tandem oxidative two-component reaction of aromatic hydrocarbons of petroleum naphtha in the absence of any other oxidizing reagent or initiator.

Application of 5331-91-9, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.5331-91-9, Name is 5-Chlorobenzo[d]thiazole-2(3H)-thione, molecular formula is C7H4ClNS2. In a patent, introducing its new discovery.

The first catalytic asymmetric desymmetrization of azetidines is disclosed. Despite the low propensity of azetidine ring opening and challenging stereocontrol, smooth intermolecular reactions were realized with excellent efficiency and enantioselectivity. These were enabled by the suitable combination of catalyst, nucleophile, protective group, and reaction conditions. The highly enantioenriched densely functionalized products are versatile precursors to other useful chiral molecules. Mechanistic studies, including DFT calculations, revealed that only one catalyst molecule is involved in the key transition state, though both reactants can be activated. Also, the Curtin-Hammett principle dictates the reaction proceeds via amide nitrogen activation.

A document type is Article, introducing its new discovery.

In order to discover novel hypoxia-inducible factor 1 (HIF-1) inhibitors for the cancer metastasis treatment, 68 new aryl carboxamide compounds were synthesized and evaluated for their inhibitory effect by dual luciferase-reporter assay. Based on five rounds of investigation on structure-activity relationships step by step, compound 30m was discovered as the most active inhibitor (IC50 = 0.32 muM) with no obvious cytotoxicity (CC50 > 50 muM). It effectively attenuated hypoxia-induced HIF-1alpha protein accumulation and reduced transcription of vascular epidermal growth factor in a dose-dependent manner, which was further demonstrated by its inhibitory potency on capillary-like tube formation, angiogenesis of zebrafish as well as cellular migration and invasion. Importantly, compound 30m exhibited antimetastatic potency in breast cancer lung metastasis in the mice model, indicating its promising therapeutic potential for prevention and treatment of tumor metastasis. These results definitely merit attention for further rational design of more efficient HIF-1 inhibitors in the future.
