  Acylhydrazones as Widely Tunable Photoswitches

  摘要：

  Molecular photoswitches have attracted much attention in biological and materials contexts. Despite the fact that existing classes of these highly interesting functional molecules have been heavily investigated and optimized, distinct obstacles and inherent limitations remain. Considerable synthetic efforts and complex structure property relationships render the development and exploitation of new photoswitch families difficult. Here, we focus our attention on acylhydrazones: a novel, yet underexploited class of photochromic molecules based on the imine structural motif. We optimized the synthesis of these potent photoswitches and prepared a library of over 40 compounds, bearing different substituents in all four crucial positions of the backbone fragment, and conducted a systematic study of their photochromic properties as a function of structural variation. This modular family of organic photoswitches offers a unique combination of properties and the compounds are easily prepared on large scales within hours, through an atom-economic synthesis, from commercially available starting materials. During our thorough spectroscopic investigations, we identified photoswitches covering a wide range of thermal half-lives of their (Z)-isomers, from short-lived T-type to thermally stable P-type derivatives. By proper substitution, excellent band separation between the absorbance maxima of (E)- and (Z)-isomers in the UV or visible region could be achieved. Our library furthermore includes notable examples of rare negative photochromic systems, and we show that acylhydrazones are highly fatigue resistant and exhibit good quantum yields.

• Oral pharmaceutical compositions containing cyclodextrins as taste masking agent
  申请人：——

  The application discloses oral pharmaceutical compositions which are tasted in the mouth during administration. Fast-dissolving tablets, chewable tablets and effervescent dispersions are exemplified. To mask the taste of unpleasant-tasting active ingredients, it has been found that blending with cyclodextrin without the conventional complex formation is effective. Consequently more economical modes of manufacture such as simple granulation and dry blending can be used.

  该申请揭示了口服制剂，其在给药过程中在口腔中被品尝。快速溶解片剂、可咀嚼片剂和泡腾分散剂是示例。为了掩盖令人不愉快的活性成分的味道，发现与β-环糊精混合而无需传统的复合形成是有效的。因此，可以使用更经济的制造方式，如简单的制粒和干混合。
