  2,6-Difluorophenol as a Bioisostere of a Carboxylic Acid:  Bioisosteric Analogues of γ-Aminobutyric Acid

  摘要：

  3-(Aminomethyl)-2,6-difluorophenol (6) and 4-(aminomethyl)-2,6-difluorophenol (7) were synthesized in eight and four steps, respectively, starting from 2,6-difluorophenol, to test the potential of the 2,6-difluorophenol moiety to act as a lipophilic bioisostere of a carboxylic acid. Compounds 6 and 7 are potential bioisosteric analogues of gamma-aminobutyric acid (GABA). Substrate studies and inhibition studies were carried out with pig brain gamma-aminobutyric acid aminotransferase; 6 and 7 are very poor substrates, but both inhibit the enzyme, indicating that the 2,6-difluorophenol moiety appears to be able to substitute for a carboxylic acid to increase the lipophilicity of drug candidates.

  Disclosed is a series of materials, which exhibit large birefringence under the influence of an applied electric field. These materials are capable of switching this large birefringence with a characteristic time on the order of 1 microsecond or less. In addition, these materials have good optical loss at this wavelength, and are stable under irradiation. These materials are suitable for fabrication of optical devices such a variable optical attenuators, switches, and modulators that respond in these time frames or slower. These materials are also suitable for use across a wide range of wavelengths. As a second component of this invention, some of these novel materials exhibit these desired optical properties (large birefringence, low loss, stability under illumination) at wavelengths as short as about 400 nm. These materials are suitable for fabrication of optical devices operating at or about 405 nm, where conventional EO materials strongly absorb and/or quickly degrade.
