  • [mass noun] Any of a group of polycyclic compounds produced by fungi, used experimentally in research for their property of interfering with cell processes.

    • ‘At low concentrations, cytochalasin D is reported to inhibit actin polymerization.’
    • ‘Cells at a reduced cholesterol concentration were treated with cytochalasin D.’
    • ‘We measured the effect of cytochalasin D mobilization of integrins on adhesion of a leukocyte cell line to both cultured endothelium and purified ligand substrates.’
    • ‘In experiments that test the effect of actin, cells were incubated for 30 min before experiments in medium containing 20 M cytochalasin D to disrupt actin filaments.’


1960s: from cyto- ‘cell’ + Greek khalasis dislocation.
