“…+++ +++ ++ ++ +++ + --: no activity (<10 mm); +: activity (10-15 mm); ++: good activity (15-20 mm); +++: very good activity (>20 mm) (Mazzini et al, 2001;Tong et al, 2004;Chen et al, 2005). Hypocrellins, as dominant compounds, were extracted from S. bambusicola (Wan and Chen, 1981), and have attracted a great deal of attention because of their lightinduced antifungal, antiviral and antitumor activity, especially against the human immunodeficiency virus (HIV) (Kocisova et al, 1999;Wang et al, 1999;Mirossay et al, 2000;Xu et al, 2001;Yang et al, 2001;Ali and Olivo, 2002;Deininger et al, 2002;Zhou et al, 2003;Chin et al, 2004).…”

“…The helical chirality of 94 is needed to direct the stereochemistry of the aldol cyclization, but following formation of the seven-membered ring, the integrity of the helical axis is lost due to the rapid atropisomerization of 73 (4:1, P : M ) at room temperature (Scheme 21). 56…”

Total synthesis of chiral biaryl natural products by asymmetric biaryl coupling

2009

View full text Add to dashboard Cite

This tutorial review highlights the use of catalytic asymmetric 2-naphthol couplings in total synthesis. The types of chirality, chiral biaryl natural products, prior approaches to chiral biaryl natural products, and other catalytic asymmetric biaryl couplings are outlined. The three main categories of chiral catalysts for 2-naphthol coupling (Cu, V, Fe) are described with discussion of their limitations and advantages. Applications of the copper catalyzed couplings in biomimetic syntheses are discussed including nigerone, hypocrellin, calphostin D, phleichrome, and cercosporin.

“…The stroma of this species has been used as a traditional medicine in China (Cheng et al 2004). To date, extensive studies have been conducted on compounds of S. bambusicola, which have been found to be involved in antitumor activity and antiangiogenesis (Mazzini et al 2001;Tong et al 2004;Chen et al 2005). The products, which were characterized by the name hypocrellins, form perylenequinone pigments.…”

Taxonomic characterization of Shiraia-like fungi isolated from bamboos in Japan

et al. 2008

The molecular phylogeny of nuclear LSU rDNA sequences (D1/D2 domain), ITS regions, and beta-tubulin gene (tub2) showed that the seven strains of Shiraia-like fungi obtained from fresh bamboo tissues as endophytes were closely related to Shiraia bambusicola and had three distinctive lineages (groups A-C). The closest group (group A) to S. bambusicola produced distinctive prawn-shaped conidioma-like structures that differed from conidiomata in the anamorph of S. bambusicola. Currently, none of the morphological structures and molecular database records were compatible with our Shiraia-like fungi. These results reveal that Shiraia-like fungi group A is supposed to be a new species that should be assigned into a novel genus/ species related to S. bambusicola.
