实验参考方法

Cell experiment [1-3]:

Cell lines

HeLa, Vero, L, HEp2, and MDBK cells, SC-1 cells, Murine CT26 colorectal carcinoma cells

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

0.2–0.5 μg/ml

Applications

In HeLa, Vero, L, HEp2, and MDBK cells, cytochalasin D (0.2–0.5 μg/ml) induced sustained contraction (contracture), loss of microvilli, expression of endoplasmic contents (zeiosis), nuclear protrusion, and extension of cytoplasmic processes. Cells in G1 were most sensitive to CD; responsiveness decreased progressively during early S and is least in mid S through G2. CD inhibited transport of [14C]deoxyglucose in HeLa. In SC-1 cells, Cytochalasin D treatment severely disrupted network organization, increased the number of actin filament ends, and led to the formation of filamentous aggregates or foci composed mainly of actin filaments. Cytochalasin D (0.24~15 μg/mL, 16 h) inhibited CT26 tumor cell proliferation in time and dose dependent manner and induced significant CT26 cell apoptosis.

Animal experiment [3,4]:

Animal models

Murine CT26 tumor model, porcine coronary model

Dosage form

Intravenous injection, 50 mg/kg, every 3 days for 21 days

Application

Cytochalasin D (i.v., 50 mg/kg) in vivo treatment significantly inhibited tumor growth and prolonged the survival times in CT26 tumor-bearing mice. In porcine coronary model, Cytochalasin D (2 μg) resulted in less late lumen loss in low-dose. High-dose Cytochalasin D (20 μg) inhibited both late lumen loss and intimal area.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

The cytochalasins are cell-permeable fungal metabolites that inhibit actin polymerization.[1],[2],[3],[4] This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion.[5],[6],[7],[8] Cytochalasin D is a cell-permeable inhibitor that binds actin filaments, but not actin monomers, to inhibit polymerization at concentrations as low as 0.2 µM.2 In this way, it prevents the migration of tumor cells.[9]

细胞毒霉素是一种可渗透进入细胞的真菌代谢产物,可以抑制肌动蛋白聚合。这会干扰诸如细胞运动、生长、吞噬作用、颗粒释放和分泌等多种过程。其中,细胞毒霉素D是一种可渗透进入细胞的抑制剂,它能够结合肌动蛋白丝而不是单体肌动蛋白,在低至0.2微米的浓度下抑制聚合反应。通过这种方式,它可以阻止肿瘤细胞的迁移。
