  脂肪族醛的旋转相及其对植物蜡晶体生长的影响

  摘要：

  采用差示扫描量热法和高温X射线衍射法合成并分析偶数C 22-32脂肪醛。醛被确定结晶成三斜晶系、单斜晶系和正交晶系，并经历固-固转变为旋转 ( R ) 相。对于偶数醛，观察到偶数和奇数正构烷烃的所有已知R相。此外，植物角质层蜡的两种代表性成分——三十烷醛和正九烷的二元混合物被确定为在三种成分（25:75、50:50、75:25）下部分混溶，并且同样具有R型阶段。许多植物表现出突变，其中表皮蜡中醛的表达显着降低。受影响的突变体通常是无毛的，缺乏角质层蜡晶体，并且具有增加的角质层通透性和不耐旱性。我们提出醛作为混溶性中介物，它们的R相可能为植物中的蜡晶体生长提供一种机制。

  Pharmaceutical compositions comprising a fatty acid salt, a dicarboxylic acid salt, an alkyl sulfate salt, an aryl sulfate salt or an alkyl aryl sulfonate salt of methylene blue or a derivative of methylene blue are described herein. The compositions are preferably administered orally and can be administered as tablets, soft or hard shell capsules (e.g. soft gelatin capsules), suspensions or solutions. The composition can also be formulated as a suppository or enema or rectal administration. The compositions further comprise a pharmaceutically acceptable carrier and optionally one or more pharmaceutically acceptable excipients. Suitable excipients include diluents, binders, plasticizers, lubricants, disintegrants, colorants, stabilizers, surfactants, and combinations thereof. The fatty acid salts, alkyl sulate salts, aryl sulfate salts or alkyl aryl sulfonate salts can be co-mixed or co-melted with one or more fatty acids to make more hydrophobic compositions, which may result in less staining formulations. The compositions can be formulated for immediate release, controlled release such as extended release, delayed release, and pulsatile release, or combinations thereof. In one embodiment, the derivative of methylene blue is methylene dodecylsulfate.
