Cytochalasin B inhibits thyroid secretion
Biochemical and Biophysical Research Communications, 1971The addition in vitro of cytochalasin B at concentrations of 0.5–3.0 μg/ml to prelabeled mouse thyroid glands interferes with release of iodine derived from thyroglobulin and blocks colloid endocytosis. It is suggested that cytoplasmic microfilaments are involved in the secretory process.

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 ...

Cytochalasin B induces cellular DNA fragmentation
The FASEB Journal, 1990Cellular DNA fragmentation can be induced in many biological instances without plasma membrane damage. The fungal metabolite, cytochalasin B, is capable of modifying numerous cellular functions related to DNA synthesis. In this work it is demonstrated that cytochalasin B is capable of inducing DNA fragmentation in a number of cells

Cytochalasin sensitive structures and lymphocyte activation
Experimental Cell Research, 1976Abstract In purified human peripheral blood lymphocytes, low (0.01–10 μM) concentrations of cytochalasins A B, E and D (CA, CB, CD, CE) produced marked augmentation of transport and metabolic responses to phytohemagglutinin (PHA) and concanavalin A (ConA) including effects on DNA synthesis, cAMP accumulation, phosphatidylinositol turnover and sodium ...

Cytochalasin D fromHypocrella Bambusae
Journal of Asian Natural Products Research, 2001Cytochalasin D which shows marked cytotoxic effects on multi-tumor cells was newly isolated at high content(5.28 mg/g, dry weight) from Fungus Hypocrella bambusae(B.et Br.) Sacc. Its structure was elucidated by spectroscopic methods. Two-dimensional NMR techniques were applied to make complete assignment for the 1H- and 13C-NMR chemical shifts of this ...

Cytochalasins from Phoma exigua var. Heteromorpha
Phytochemistry, 1991Abstract Three further cytochalasins from Phoma exigua var. heteromorpha , grown on wheat, were isolated and characterized by spectroscopic methods and by chemical correlation with cytochalasin B. They were identified as cytochalasin T, a new 24-oxa[14]cytochalasan, cytochalasin F and 7- O -acetylcytochalasin B, both isolated for the first time ...

Cellular Effects of Cytochalasins
1990Recent progress in cell biology and biochemistry has clarified the proteins involved in cell structure, function, and movement; microtubules composed of tubulin and microfilaments composed of actin play the most important roles in these cellular phenomena.
