Cytochalasins: Structure-activity relationships

open access: yesPhytochemistry, 1990
Abstract Seven cytochalasins, 17- O -acetylcytochalasin A and two derivatives of cytochalasin B were assayed for Pseudomonas syringae , Bacillus megaterium , and for Geotrichum candidum . Their ability to inhibit the growth of tomato seedlings and their toxicity to brine shrimp (% larvae mortality were also investigated.

Cytochalasin-u and Cytochalasin-v, 2 New Cytochalasins, From Phoma-exigua Var Heteromorpha

open access: yes, 1992
Two additional cytochalasins were isolated from liquid culture filtrates of Phoma exiqua var. heteromorpha together with some already known cytochalasins. The two new metabolites, named cytochalasin U and V, represent the first natural occurrence of a 25,26-dioxa[16] and 25-oxa[15]cytochalasan, respectively, both bearing a formyl group on the ...

Cytochalasins Z1, Z2 and Z3, three 24-oxa[14]cytochalasans produced by Pyrenophora semeniperda

open access: yesPhytochemistry, 2002
Three new cytochalasans, named cytochalasins Z1, Z2 and Z3, were isolated from the wheat culture of Pyrenophora semeniperda, a fungus proposed to biol. control grass weeds. Other cytochalasins isolated from the same org. ext.

Cytochalasin binding to macrophages

Cellular Immunology, 1978
Cytochalasin-sensitive structures are involved in macrophage motility, membrane recognition phenomena and the internalization of phagocytic particles. The purpose of this study was to characterize the binding of cytochalasins to rabbit alveolar macrophages.

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.
