Effects of Cytochalasins on Lymphocytes: Some Distinctive Features of Cytochalasin-E

Journal of Immunopharmacology, 1984
Cytochalasin-E (CE) has specific properties that distinguishes it from other cytochalasin congeners. We have taken advantage of these in investigating the mechanisms operative in the effects of cytochalasins on lymphocyte proliferative responses to phytomitogens.

Cytochalasins and an Abietane-Type Diterpenoid with Allelopathic Activities from the Endophytic Fungus Xylaria Species.

Journal of Agricultural and Food Chemistry, 2019
Bioactivity-guided isolation of the cultures of the endophytic fugus Xylaria sp. XC-16 residing in a deciduous tree Toona sinensis led to the discovery of four new allelochemicals (1-4), including three cytochalasins, epoxycytochalasin Z17 (1 ...

Teratogenicity of cytochalasin D in the mouse

Teratology, 1977
AbstractCytochalasin D, a mold metabolite identified in food, was injected intraperitoneally in doses of 0.4 to 0.9 mg per kilogram on gestational days 7 through 11 and produced evidence of teratogenicity in two out of three strains of mice. Exencephaly, hypognathia and axial skeletal defects were found in strains C57BL/6J and BALB/c while no increase ...

Antifungal activities of cytochalasins produced by Diaporthe miriciae, an endophytic fungus associated with tropical medicinal plants.

Canadian Journal of Microbiology (print), 2018
In the present study, we evaluated the antifungal potential of cytochalasins produced by Diaporthe taxa against phytopathogenic fungi. Using molecular methods, seven endophytic fungal strains from the medicinal plants Copaifera pubiflora and Melocactus ...

Enhancement of viral infectivity by cytochalasin

Virology, 1973
Abstract Cytochalasins B and D enhance the infectivity of poliovirus; a 5-fold increase in viral titer occurs on treatment of cells with 4–6 μg/ml of either congener. At lower concentrations, however, CD is more effective than CB in increasing the infectibility of cells.

Cytochalasins from an Australian Marine Sediment-Derived Phomopsis sp. (CMB-M0042F): Acid-Mediated Intramolecular Cycloadditions Enhance Chemical Diversity.

Journal of Organic Chemistry, 2017
Chemical analysis of an Australian coastal marine sediment-derived fungus, Phomopsis sp. (CMB-M0042F), yielded the known cytochalasins J (1) and H (2), together with five new analogues, cytochalasins J1-J3 (3-5) and H1 and H2 (6 and 7). Structures of 1-7

The structures of cytochalasins A and B

Journal of the Chemical Society C: Organic, 1967
The structures of cytochalasins A and B, metabolites of Helminthosporium dematioideum showing novel effects on mammalian cells, have been determined. Cytochalasin B is identical with phomin. (–)-α-Methyladipic acid is shown to have the R-configuration contrary to a previous assignment; the absolute configurations of the Nupheus alkaloids therefore ...

The binding sites of cytochalasin D. II. Their relationship to hexose transport and to cytochalasin B

Journal of Cellular Physiology, 1977
AbstractCytochalasin B (CB) was able to compete with tritiated cytochalasin D (3H‐CD) for binding sites in HEp‐2 cells. The pattern of inhibition suggested that CB associates with a low affinity class of CD binding sites. Glucose and maltose did not inhibit binding of 3H‐CD to isolated HEp‐2 plasma membrane.

Actin assembly activity of cytochalasins and cytochalasin analogs assayed using fluorescence photobleaching recovery

Archives of Biochemistry and Biophysics, 1988
The effects on actin self-assembly of 9 common cytochalasins and 9 synthetic analogs have been assayed using fluorescence photobleaching recovery (FPR). The specific assembly activities of cytochalasins determined by this assay are (i) reduction of the fraction of actin molecules incorporated into filaments; (ii) increase of the steady-state diffusion ...

Characterization of cytochalasins from the endophytic Xylaria sp. and their biological functions.

Journal of Agricultural and Food Chemistry, 2014
Bioassay-guided fractionation of the fermentation extract of Xylaria sp. XC-16, an endophyte from Toona sinensis led to the isolation of two new cytochalasans cytochalasin Z27, 1, and cytochalasin Z28, 2, along with three known compounds seco ...
