製品説明

IC₅₀ & Target

Kd: 2.2 nM (F-actin, with Mg²⁺), 1.4 nM (F-actin, with Mg²⁺/K⁺)^[1]

体外実験

Cytochalasin B is a cell-permeable mycotoxin binding to the barbed end of actin filaments, inhibits the enlongation and shortening of actin filaments, with K_ds of 2.2 nM and 1.4 nM for F-actin in the presence of MgCl₂ (2 mM) or MgCl₂ (2 mM) plus KCl, respectively^[1]. Cytochalasin B (0.1-10 μM) shows inhibitory effect on multiple murine cancer cell lines, with IC₅₀s of 2.56 μM (M109c), 10.46 μM (B16BL6), 105.5 μM (P388/ADR), 51.9 μM (P388/S) and IC₈₀s of 12.23 μM (M109c), 44.86 μM (B16BL6), 188.4 μM (P388/ADR), 84.1 μM (P388/S) after treatment for 3 h, with IC₅₀s of 0.25 μM (M109c), 0.37 μM (B16F10), 0.87 μM (B16BL6), and IC₈₀s of 0.75 μM (M109c), 1.21 μM (B16F10), 10.41 μM (B16BL6) after treatment for 4 days^[2]. Cytochalasin B (6 μM) increases the myofibrillar fragmentation index (MFI), which is attributed to the intensely breaking of myofibrillar proteins into short segments. Cytochalasin B also accelerates the disruption of actin filaments. In addition, Cytochalasin B accelerates the transformation from F-actin to G-actin, lowering the content of F-actin and significantly increasing G-actin bands during postmortem conditioning^[3].

体内実験

Cytochalasin B (10, 25, 50 mg/kg, i.p.) dose-dependently increases the life expectancy of Balb/c mice bearing with P388/ADR leukemias. Cytochalasin B at 50 mg/kg produces 10 % long-term survival in the multidrug resistant P388/ADR cohort, and 40 % long-term survival in the drug sensitive P388/S cohort^[2].

細胞実験

The attached cell lines M109c, B16BL6, and B16F10 are seeded at 1 to 4 × 10⁴ cells/mL in 2 mL volumes in 24-well culture plates 1 day prior to treatment with Cytochalasin B. The suspension culture of P388/ADR cells is seeded at 5 × 10⁴ cells/mL and allowed to grow overnight before Cytochalasin B treatment. Cells are treated with Cytochalasin B for 3 h, as well as 2, 3, or 4 days. In the case of continuous exposure for 2, 3, or 4 days, attached cells are trypsinized and counted with a hemacytometer. Leukemia cell suspensions are counted with a Coulter Counter. In the case of short-term exposure, cells are washed twice with fresh medium, then trypsinized (except for P388/ADR cells), reseeded, and allowed to regrow for 3 days, at which time they are counted. Growth results are calculated as the number of cells generated above the seeding density compared to the untreated control cells and graphically presented as percent of control increase^[2].

動物実験
^[2]

Mice^[2]
For chemotherapy testing, Balb/c mice under isoflurane anesthesia are challenged with 2 × 10⁵ trypan blue negative P388/S or P388/ADR cells subcutaneously (s.c.) in a volume of 200 μL. Untreated mice are kept in order to determine the lethality of the challenge without chemotherapeutic intervention. Long-term survival is defined as challenged mice that survive the duration of the observation period. Cytochalasins B and D are prepared in suspension form in 2 % carboxymethyl cellulose 1 % tween 20 (CMC/Tw) for intraperitoneal (i.p.) administration. The congeners or the vehicle are administered to leukemia-challenged mice on Days 1-8 following the initial challenge^[2].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
