Cytochalasin
Cytochalasins are fungal metabolites that have the ability to bind to actin filaments and block polymerization and the elongation of actin. As a result of the inhibition of actin polymerization, cytochalasins can change cellular morphology, inhibit cellular processes such as cell division, and even cause cells to undergo apoptosis. Cytochalasins have the ability to permeate cell membranes, prevent cellular translocation and cause cells to enucleate. Cytochalasins can also have an effect on other aspects of biological processes unrelated to actin polymerization. For example, cytochalasin A and cytochalasin B can also inhibit the transport of monosaccharides across the cell membrane, cytochalasin H has been found to regulate plant growth, cytochalasin D inhibits protein synthesis and cytochalasin E prevents angiogenesis. Binding to actin filaments Cytochalasins are known to bind to the barbed, fast growing plus ends of microfilaments, which then blocks both the assembly and disassem ...

Cytochalasin B
Cytochalasin B, the name of which comes from the Greek ''cytos'' (cell) and ''chalasis'' (relaxation), is a cell-permeable mycotoxin. It was found that substoichimetric concentrations of cytochalasin B (CB) strongly inhibit network formation by actin filaments. Due to this, it is often used in cytological research. It inhibits cytoplasmic division by blocking the formation of contractile microfilaments. It inhibits cell movement and induces nuclear extrusion. Cytochalasin B shortens actin filaments by blocking monomer addition at the fast-growing end of polymers. Cytochalasin B inhibits glucose transport and platelet aggregation. It blocks adenosine-induced apoptotic body formation without affecting activation of endogenous ADP-ribosylation in leukemia HL-60 cells. It is also used in cloning through nuclear transfer. Here enucleated recipient cells are treated with cytochalasin B. Cytochalasin B makes the cytoplasm of the oocytes more fluid and makes it possible to aspirate the nuc ...

Cytochalasin E
Cytochalasin E, a member of the cytochalasin group, is an inhibitor of actin polymerization in blood platelets. It inhibits angiogenesis and tumor growth. Unlike cytochalasin A and cytochalasin B, it does not inhibit glucose transport. Cytochalasin E, however, was noted to decrease glucose absorption in mice around the intestinal tissues by increasing the Km needed for glucose to reach the Vmax, which meant that a higher concentration of glucose was required in its presence to attain Vmax. Since Vmax remained the same according to another study, it is evident that CE is indeed a competitive inhibitor at the intestinal receptor sites for glucose. Because of its antiangiogenic effect, cytochalasin E is a potential drug for age-related macular degeneration, a kind of blindness caused by an abnormal proliferation of blood vessels in the eye. Cytochalasin E was found to be a potent and selective inhibitor of bovine capillary endothelial (BCE) cell proliferation. Cytochalasin E differs ...

Cytoskeletal Drugs
Cytoskeletal drugs are small molecules that interact with actin or tubulin. These drugs can act on the cytoskeletal components within a cell in three main ways. Some cytoskeletal drugs stabilize a component of the cytoskeleton, such as taxol, which stabilizes microtubules, or Phalloidin, which stabilizes actin filaments. Others, such as Cytochalasin D, bind to actin monomers and prevent them from polymerizing into filaments. Drugs such as demecolcine act by enhancing the depolymerisation of already formed microtubules. Some of these drugs have multiple effects on the cytoskeleton: for example, Latrunculin both prevents actin polymerization as well as enhancing its rate of depolymerization. Typically the microtubule targeting drugs can be found in the clinic where they are used therapeutically in the treatment of some forms of cancer. As a result of the lack of specificity for specific type of actin (i.e. cannot distinguish between cardiac, smooth muscle, muscle and cytoskeletal for ...
