Carboxymethyl chitosan
Based on 1 Customer Validation
Carboxymethyl chitosan is a derivative of chitosan. Carboxymethyl chitosan inhibits Apoptosis and ROS. Carboxymethyl chitosan increases the expression of Bcl-2 and reduces the expression of Bax, cytochrome c and caspase-3. Carboxymethyl chitosan inhibits the migration of various cells. Carboxymethyl chitosan exerts antitumor effects on Lewis tumors and hepatocarcinoma.

In Vitro
Carboxymethyl chitosan (100 μg/mL; 4 days) promotes the proliferation of normal skin fibroblasts but inhibits the proliferation of keloid fibroblasts[1].
Carboxymethyl chitosan hydrogels show enhanced cell migration compared with standard chitosan hydrogels[2].
Carboxymethylated chitosan (50-200 μg/mL; 8 h) increases the viability of Schwann cells exposed to H2O2 and decreases LDH release in a concentration-dependent manner[3].
Carboxymethyl chitosan (0.5-2.0 mg/mL; 24-48 h) significantly inhibits the migration of human umbilical vein endothelial cells (HUVECs)[4].
Carboxymethyl chitosan (50-200 μg/mL; 1 h) inhibits IL-1β-induced apoptosis of rabbit chondrocytes in a dose-dependent manner[5].
Carboxymethyl chitosan (4.0-5.0 mg/mL; 48 h) decreases viability of OS-RC-2, NCI-H1650, and HT-29 cells[6].
Carboxymethyl chitosan (1.0-5.0 mg/mL; 12-24 h) can significantly inhibit the two-dimensional migration of BEL-7402 cells in a dose-dependent manner[7].

Cell Line:Schwann cells
-
Concentration:5, 100, 200 μg/mL
-
Incubation Time:8 h
-
Result:Increased the expression of the anti-apoptotic protein Bcl-2 and decreased the expression of the pro-apoptotic proteins Bax, cytochrome c, and caspase-3.
Reduced cell apoptosis rates by 45.9%, 23.2%, and 9.3% at concentrations of 5 μg/mL, 100 μg/mL, and 200 μg/mL, respectively.
In Vivo
Carboxymethyl chitosan (20-120 mg/kg; i.v.; every other day; for seven times) can significantly inhibit the growth of Lewis tumor tissue, increase the spleen index of tumor-bearing mice, and make the liver and lung cells arrange more orderly, indicating its effectiveness in repressing Lewis tumor growth and metastasis[6].
Carboxymethyl chitosan (1350 mg/kg; i.p.) has no significant effects on the coagulation, anticoagulation, fibrinolysis, or hemorheology parameters of rats[8].
