Cytotoxic azaphilone alkaloids from Chaetomium globosum TY1

Bioorganic & Medicinal Chemistry Letters, 2013
Three novel azaphilone alkaloids, namely chaetomugilides A-C (1-3), together with three related compounds (4-6) were isolated from the methanol extract of Chaetomium globosum TY1, an endophytic fungus isolated from Ginkgo biloba. Their structures were elucidated on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis ...

Chaetoglobosin Y, a new cytochalasan from Chaetomium globosum

Fitoterapia, 2014
Chaetoglobosin Y (1), was isolated from the endolichenic fungal strain Chaetomium globosum (No. 64-5-8-2), along with related six known cytochalasans, chaetoglobosin Fex (2), chaetoglobosin E (3), isochaetoglobosin D (4), chaetoglobosin G (5), cytoglobosin B (6), and cytoglobosin C (7).

Four cytochalasin alkaloids produced by Chaetomium globosum

Tetrahedron Letters, 2020
Abstract A new adduct of chaetoglobosin and aureonitol derivative, aureochaeglobosin D, with three new alkaloids cytoglobosin J-L were isolated from the solid culture of an endophytic Chaetomium globosum harbored in Pinellia ternata. The structures were elucidated by detailed spectroscopic analysis.

Synthesis of β-linked glucosaccharides by extracts of Chaetomium globosum

Biochimica et Biophysica Acta, 1954
Cell-free extracts of mycelium of Chaetomium globosum, grown under specified conditions, were shown to cause dissimilation of cellobiose into glucose and a trisaccharide, which by chemical and physical tests was identified as cellotriose. In the presence of notatin (glucose oxidase) the synthesis proceeded further and certain simple oligosaccharides ...

Germination of Chaetomium globosum ascospores on hardwoods

Transactions of the British Mycological Society, 1979
The sapwood of Tilia europaea L. was found to possess a substance capable of inhibiting germination of ascospores of Chaetomium globosum Kunze ex Fr. The inhibitory substance could be leached from sapwood blocks placed end grain in contact with water agar. Volatile activity of the substance was also demonstrated after oven sterilization of the wood.

Biotransformation of pseudolaric acid B by Chaetomium globosum

Process Biochemistry, 2011
Pseudolaric acid B (1) is a natural product with potent antifungal activity. We discovered that pseudolaric acid B did not kill but only suppress the growth of the filamentous fungus Chaetomium globosum. It was proposed that pseudolaric acid B was converted to metabolites with decreased antifungal activities.

Spore Dispersal in Chaetomium globosum (Kunze)

Nature, 1961
IN the genus Chaetomium the fruit-body, a perithecium, is ornamented with a large number of apical hairs which are either spirally coiled or dichotomously branched. The ascospores are released within the perithecium by breakdown of the ascal walls and the spores ooze out of the ostiole and either form a spore tendril or become entrapped in the apical ...

SUGAR ABSORPTION BY CHAETOMIUM GLOBOSUM

New Phytologist, 1962
SummaryThe absorption of the sugars, glucose and fructose, by Chaetomium globosum does not involve an accumulation against an internal concentration but is associated with immediate assimilation. The process is sensitive to the presence of inhibitors, anaerobiosis, and to the concentration supplied.

Antioxidant activity of a polysaccharide produced by Chaetomium globosum CGMCC 6882

International Journal of Biological Macromolecules, 2019
In present work, a polysaccharide (GCP-WS) was successfully produced by Chaetomium globosum CGMCC 6882 from wheat straw. Monosaccharide composition of GCP-WS was rhamnose, glucosamine, galactose, glucose, xylose, fructose and glucuronic acid in a molar ratio of 21.46:1.58:1.11:55.15:36.37:7.04:7.34. Meanwhile, molecular weight of GCP-WS was 3.538 × 104
