Boronic Acids in Molecular Self‐Assembly

Chemistry – An Asian Journal, 2008
AbstractThe reversibility of boronic acid and diol interaction makes it an ideal candidate for the design of self‐assembled molecular structures. Reversibility is required to ensure that the thermodynamically most stable structure is formed. Reversibility also ensures that any errors produced during the assembly process are not permanent.

Sugar complexation to silicone boronic acids

Chemical Communications, 2013
A new class of surface-active compounds based on the combination of silicones and boronic acids is described. The properties of the compounds can be tuned by manipulation of both the hydrophobic (silicone size and 3D structure) and hydrophilic components (by binding different saccharides to the boronic acid).

(2-Methoxy-3-pyridyl)boronic acid

Acta Crystallographica Section C Crystal Structure Communications, 2006
The structure of the title compound, 2-CH3O-C5H3N-3-B(OH)2 or C6H8BNO3, comprises two crystallographically independent molecules. The molecules are linked to each other by intermolecular O-H...N and C-H...O bonds to produce an infinite chain, while a two-dimensional structure is formed as a result of pi-pi interactions of planar molecules.

A facile oxidation of boronic acids and boronic esters

Tetrahedron Letters, 1995
Abstract Several boronic acids and boronic esters have been converted to the corresponding alcohols in good to excellent yields. The oxidant was oxone® (potassium peroxymonosulfate, 2KHSO5·KHSO4·K2SO4) and the reactions were performed in 10 to 15% aqueous acetone and buffered with sodium bicarbonate.

Boronic acid compounds as potential pharmaceutical agents

Medicinal Research Reviews, 2003
AbstractBoronic acid compounds have been used, because of their unique structural features, for the development of potent enzyme inhibitors, boron neutron capture agents for cancer therapy, and as antibody mimics that recognize biologically important saccharides. Consequently, there has been a surge of interests in boronic acid compounds.

Boron Containing Nucleic Acids

1992
The radiobiological effectiveness of the neutron capture reaction is thought to be twice as great if it occurs in the cell nucleus rather than in the cytoplasm.1.2 To enhance the probability of localization in the cell nucleus, we have been carrying out the synthesis of a variety of boronated nucleic acids.

Comparison Study of Alkyl Boronic Acids with Boric Acid

Journal of Pharmaceutical Sciences, 1962
The bacteriostatic activities of two alkyl boronic acids were compared with boric acid. Some primary irritation and chronic toxicity determinations of the compounds were also accomplished. The results indicated that nonyl boronic acid and dodecyl boronic acid possessed bacteriostatic activity superior to boric acid, and that very dilute concentrations ...

Peptide Boronic Acid Inhibitors of Thrombin

1993
Fibrin polymerization is the major component in venous thrombosis while both fibrin deposition and platelet aggregation are important in arterial thrombosis. Thrombin, the last protease in the blood coagulation cascade, hydrolyzes two bonds of fibrinogen to convert it into insoluble fibrin. Thrombin also catalyzes platelet aggregation.
