Preparation, Modification, and Hybridization of One-Dimensional Ionic Ladder-Like Polysilsesquioxanes
Published in Kazuhiro Shikinaka, Functionalization of Molecular Architectures, 2018
Hybrids formed by noncovalent interactions between photo- functional and chiral compounds have attracted attention owing to their potential applications as circularly polarized luminescent (CPL) materials. To prepare these hybrids, several combinations have been investigated, such as laser dye-cholesteric liquid crystal, anionic dye-cationic chiral surfactant, pyrene derivative- cyclodextrin, π-conjugated polymer-polysaccharide (amylose and schizophyllan), and porphyrin-helical polyacetylene [47–52]. Conversely, no reports have appeared regarding hybridization using chiral siloxane compounds. The chiral siloxane compounds capable of inducing chirality into photofunctional compounds may enable the development of durable and thermostable photofunctional hybrids because the siloxane compounds exhibit superior thermal, mechanical, and chemical stabilities. Therefore, the ladder-like PSQs containing chiral and ammonium groups, as described in the Section 3.4.1, were applied to chiral inductors for hybridization by ionic interaction with a dye compound such as the anionic achiral porphyrin, tetraphenylporphine tetrasulfonic acid (TPPS) (Fig. 3.1) [38, 39].

While it has been established that β-glucans from mushrooms have anticancer activity, the alpha-glucans does not exhibit this effect (Volman et al., 2010b). Some mushroom preparations that have demonstrated significant effect against human cancers include active hexose correlated compound (AHCC) and Lentinan (from Lentinula edodes), Maitake D-fraction (from Grifola frondosa), Schizophyllan (SPG); from Schizophyllum commune), and polysaccharide-Krestin or polysaccharide of P (PSK/PSP) from Trametes versicolor (Guggenheim et al., 2014).

Schizophyllum commune and Geopora sumneriana mushrooms are wild edible mushrooms used in traditional medicine (Ruán-Soto, Garibay-Orijel, and Cifuentes 2006; Sahin and Akata 2019). S. commune (also known as split-gill) is an essential member of the genus Schizophyllum of the Schizophyllaceae family. It is abundant during the rainy season and usually grows in dead woods. S. commune exhibits anticancer, antimicrobial, antioxidant, immune-modulating, anti-inflammatory, and hepatoprotective activities due to its active phenolic metabolites (Ivanova, Titova, and Megalinska 2015). Schizophyllan (a neutral extracellular polysaccharide) is isolated from S. commune and it has been used as an immunopotentiator in clinical treatments in Japan for patients with cancer (Daba and Ezeronye 2003). G. sumneriana (also known as cedar cup) is a member of the family Pyronemataceae, and it grows during late winter to spring close to cedar trees. In the literature, G. sumneriana has evaluated traditional medicine against a wide variety of diseases (Malik et al. 2017).
