Combinatorial Chemistry & High Throughput Screening - Volume 18, Issue 10, 2015

Bioluminescent proteins have been intensively used as high sensitive reporters in all kinds of binding assays (immuno-, nucleic acid hybridization assays, etc.) and in bioimaging. But natural luciferases do not always meet the requirements set for them as the assay reporters: thermostabitity, definite bioluminescence spectral and kinetics characteristics, stability to chemical modifications, etc. Luciferases with different appropri Read More

Multiplex simultaneous genotyping technique was developed for four polymorphisms in genes coding for blood coagulation factors and homocysteine metabolism which are considered as thrombophilia related mutations: FV Leiden, FII G20210A, MTHFR C677T, and FVII G10976A. It is based on primer extension reaction with the following bioluminescent solid-phase microassay. At that, two different in bioluminescence Read More

Multicolor luciferase reporter assays are powerful tools for simultaneously monitoring the expression of several genes. Dual-color luciferase reporter assays were established in 2004 and have been used in broad range of application from basic researches to applications in clinical research, e.g., drug screening and alternative toxicological tests. The advantage of this method is that it can be used to simultaneously Read More

Bioanalytical systems based on the Bioluminescence Resonance Energy Transfer (BRET) are widely used in fundamental biochemical studies, as well as for screening and analysis of biologically active compounds. The Renilla luciferase is the most often used energy donor in this system despite the fact that it has low bioluminescence quantum yield and demonstrates not so stable luminescence in time as the firefly lucifer Read More

This review describes the principle and applications of bioluminescent enzymatic toxicity bioassays. This type of assays uses bacterial coupled enzyme systems: NADH:FMN-oxidoreductase and luciferase to replace living organisms in developing cost-competitive biosensors for environmental, medical and industrial applications. These biosensors instantly signal chemical and biological hazards and allow for detec Read More

A series of benzo[a]pyrano[2,3-c]phenazine derivatives with a wide range of substitutions at ring C of the benzophenazine were designed and synthesized using the one-pot, four-component domino reactions. The targeted compounds were evaluated for their antitumor activities against HCT116, MCF7, HepG2 and A549 cancer cell lines in vitro. The most active compound 6{1,2,1,9} featured the CN and p-dimethylamino Read More

Pyruvate ferredoxin oxidoreductase is the crucial enzyme that involves in bioethanol synthesis pathway of Clostridium thermocellum. It is an ethanologenic organism but has been investigated less on its enzyme structure. The amino acid sequence of Pyruvate ferredoxin oxidoreductase was derived from UNIPROT and the screened crystal structure was taken as the template for homology modeling using MODELLER 9V11 Read More

(7S, 14S, 16R)- dialkyl 6-oxo-6,7,13,14-tetrahydro-7,14-methanobenzo[d]chromeno[3,4- h][1,6,3]oxathiazo-nine-14,16-dicarboxylates 4 and (S)-methyl 2-(2-methoxy-2-oxoethyl)-2,3- dihydrobenzo[d]thiazole-2-carboxylates 5 were readily synthesized in a ratio 3:1 and moderated yield by multicomponent reactions of 4-hydroxycoumarin and acetylenic esters with benzothiazole without using a catalyst. Also, The GIAO/DFT a Read More
