Echinomycin: a bifunctional intercalating antibiotic
Nature, 1974The interaction between echinomycin and circular DNA or sonicated rod-like DNA fragments shows that this antibiotic binds by a bifunctional mode of intercalation. Binding parameters for a variety of natural and synthetic DNAs vary widely, indicating that echinomycin interacts selectively with specific nucleotide sequences.

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
Fisheye lens and Luneburg lens are lenses with different refractive index distributions. Combination of two of them in an acoustic wave will pave way for special features in acoustic wave and simplify methods of focusing or defocusing acoustic energy.

Toward bifunctional antibody catalysis
Bioorganic & Medicinal Chemistry, 2006Antibodies that catalyze the deprotonation of unactivated benzisoxazoles to give the corresponding salicylonitriles were prepared using as antigen a 2-aminobenzimidazolium derivative coupled to a carrier protein via its benzene ring. The hapten was designed to induce an antibody binding site with both a base and an acid, in position to initiate proton ...

Synthesis of Bifunctional Potassium Acyltrifluoroborates [PDF]
New bifunctional potassium acyltrifluoroborate (KAT) substrates have been synthesized in gram scale using optimized reaction conditions. Chemoselective transformation of functional groups in the presence of an acyltrifluoroborate has been demonstrated, and orthogonal reactions of bifunctional KAT reagents are reported. This allows for the incorporation

Mesolevel Bifunctional Catalysis
Kinetics and Catalysis, 2020The review is focused on requirements for technical bifunctional catalysts containing, in addition to a metal phase and an acid support (zeolite), various components required for providing an effective heat and mass transfer and chemical or mechanical functions.

Astaxanthin diferulate as a bifunctional antioxidant
Free Radical Research, 2014Astaxanthin when esterified with ferulic acid is better singlet oxygen quencher with k2 = (1.58 ± 0.1) 10(10) L mol(-1)s(-1) in ethanol at 25°C compared with astaxanthin with k2 = (1.12 ± 0.01) 10(9) L mol(-1)s(-1). The ferulate moiety in the astaxanthin diester is a better radical scavenger than free ferulic acid as seen from the rate constant of ...

Bifunctional Reagents for the Crosslinking of Proteins
Angewandte Chemie International Edition in English, 1971AbstractProteins can be crosslinked by chemical compounds without any accompanying change in the complicated three‐dimensional structure. Many bifunctional reagents that can react with functional groups in the side chains of the amino acids are now known.

Publisher Summary This chapter discusses the use of bifunctional reagents to proteins, and several cross-linking reagents, such as mustards and epoxides, which have recently been used to cross-link DNA. It has been demonstrated that at least some of the cross-links join opposite strands of the reacted DNA, therefore, very interesting structural and ...

Bifunctional Agents for Imaging and Therapy
2010Multiple, complementary techniques for tumor detection, including magnetic resonance, nuclear and optical imaging, are under active development; each approach has particular strengths and advantages. Efforts are also currently underway to develop bifunctional agents, so that a single molecule can be used for imaging, therapy, and monitoring the long ...

Bifunctional electrochemical systems
Russian Chemical Reviews, 1993The electrochemical reduction and oxidation of metal ions accompanied by the formation of a film on the electrode-electrolyte boundary is discussed. The formation of a film having a mixed conduction type and consisting of oxide-hydroxide compounds of the metal denotes the presence of a new system: the electrode-film-electrolyte system, called a ...
