Biomedical applications physiologically active

Hexoses have found many biomedical applications, based mostly on their specific biological functions, but also on the unspecific (mostly protective) effects they have on tissues and organs. Considering the latter effects, hexoses have been found to exert a profound influence on the vitrification properties of ethylene glycol-based solutions used in cryobiology for the preservation of ooc)hes and other cells [95]. Glucose, mannose, and fructose have been shown to preserve physiological activities of various tissues, and have thus become important components... 

Pillararenes (PA), a new kind of paracyclophane, were first synthesized in 2008 as pillar[5]arene (PA[5]) and were recognized as a new generation of supramolecular host because of their unique pillar structural feature, nanometer-sized (<1.0nm) cavity, and multiple fiinctionalizable sites. In the last few years, these new types of compound have shown biomedical applications in the construction of artificial channels for transmembrane transport of physiologically active solutes and vesicles for drug delivery, which will be reviewed in this chapter.
