14930-96-2 Usage
Description
Cytochalasin B (14930-96-2) is a cell permeable fungal toxin which binds to the barbed end of actin, inhibiting its polymerization.1 Inhibits cell division, migration and glucose transport.2 Causes cell cycle arrest at G2/M and induces apoptosis in HCT-116 colorectal carcinoma cells.3? Cytochalasin B-induced membrane vesicles (CIMVs) retain cell surface receptors of the parent cells and retain fusion specificity with target cells.4 CIMVs are a promising new vector system for drug and biomolecule delivery due to their natural origin and participation in intercellular communication.5

Uses
Different sources of media describe the Uses of 14930-96-2 differently. You can refer to the following data:
1. Cytochalasin B is one of the most extensively studied members of a family of potent mycotoxins produced by several species of fungi. All members of the class exhibit profound effects on cytoskeletal proteins, giving rise to pronounced morphogenic activity in animals and plants. Like most cytochalsins, cytochalasin B exhibits potent inhibition of actin filament function leading to cell death by apoptosis, and displays a broad range of resultant cellular actions. Despite the common mode of action, there is evidence that individual members of this class display diverse selectivity. However, lack of comparative co-metabolite analysis has restricted a more complete understanding of their individual selectivity.
2. A cell-permeable fungal toxin used in actin polymerization studies and cytological
3. As tools in cytological research and in characterization of polymerization properties of actin, q.v.
Definition
ChEBI: An organic heterotricyclic compound, that is a mycotoxin which is cell permeable an an inhibitor of cytoplasmic division by blocking the formation of contractile microfilaments.
General Description
Cytochalasin B is a cell-permeable fungal toxin / mycotoxin that binds to the ′barbed′ end of actin / actin filaments. This binding leads to:Disruption of actin filaments and of interaction of actin filaments in solutionInhibition of actin polymerizationInhibition of subunit association and dissociationCytochalasin B is widely used in studies of glucose transporters (GLUT). Cytochalasin B is also used as an integral part of various in vitro micronucleus assay protocols.
Biochem/physiol Actions
Cell permeable fungal toxin that disrupts contractile microfilaments by inhibiting actin polymerization. This, in turn, induces DNA fragmentation, inhibits cell division, and disrupts many cell processes. Inhibits glucose transport.
Purification Methods
Purify it by MeOH extraction, reverse phase C18 silica gel batch extraction by selective elution with 1:1 v/v hexane/tetrahydrofuran, crystallisation, subjected to TLC and recrystallisation [Lipski et al. Anal Biochem 161 332 1987]. It is soluble in EtOH (3.6%), Me2CO (1%), Me2SO (37%) and Me2NCHO (49%) at 24o, and can be crystallised from the first two solvents. It interferes with cellular movement [Korm Physiol Reviews 62 672 1982].

Check Digit Verification of cas no
The CAS Registry Mumber 14930-96-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,3 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 14930-96:
(7*1)+(6*4)+(5*9)+(4*3)+(3*0)+(2*9)+(1*6)=112
112 % 10 = 2
So 14930-96-2 is a valid CAS Registry Number.
