Carrageenan
Based on 1 publication(s) in Google Scholar
Carrageenan is an antiviral and anticancer agent. Carrageenan inhibits herpes simplex virus (HSV), HIV, and hepatitis A virus (HAV) by directly binding to the viral capsid to block the attachment of viruses such as HPV to HSPG factors on the cell surface. Carrageenan delays and arrests cell cycle progression, exhibits cytotoxicity against HeLa cancer cells, and can be applied to studies related to cervical cancer, genital warts, hepatitis A, and other conditions. Carrageenan also induces acute non-immune inflammation, triggers a three-phase inflammatory response involving the release of multiple proinflammatory mediators, and causes persistent edema, hyperalgesia, and neutrophil recruitment in mice.

Activité biologique
ι-carrageenan (HY-W145523), λ-carrageenan (HY-N9470) and κ-carrageenan (HY-138962) (20-1000 μg/mL; 3-15 d) show no significant cytotoxicity against PLC/PRF/5 cells at concentrations up to 200 μg/mL. Among them, the cytotoxicity thresholds (cell viability CD50 >1000 μg/mL) of ι-carrageenan and λ-carrageenan are higher than that of κ-carrageenan (cell viability CD50=732.1 μg/mL)[2].
ι-carrageenan, λ-carrageenan, and κ-carrageenan (0.5-200 μg/mL; 15 d) potently inhibit the expression of HAV antigen in PLC/PRF/5 cells in a concentration-dependent manner in vitro, among which ι-carrageenan (ED50=2.5 μg/mL) exhibits the strongest activity, followed by λ-carrageenan (ED50=4.5 μg/mL) and κ-carrageenan (ED50=100.3 μg/mL); meanwhile, they also reduce the replication and infectivity of HAV in PLC/PRF/5 cells in a concentration-dependent manner[2].
κ-carrageenan and λ-carrageenan (250-2500 μg/mL; 72 h) exhibit moderate concentration-dependent cytotoxicity against HeLa cells, with λ-carrageenan (IC50=475 μg/mL) showing stronger activity than κ-carrageenan (IC50=550.8 μg/mL); in addition, λ-carrageenan also exerts a strong concentration-dependent antiproliferative effect and reduces cell confluence[3].
κ-carrageenan (250-2500 μg/mL; 72 h) induces concentration-dependent G2/M phase arrest in HeLa-FUCCI cells, whereas λ-CO does not alter the proportion of each cell cycle phase in HeLa-FUCCI cells[3].
κ-carrageenan and λ-carrageenan (250-2500 μg/mL; 72 h) show no significant cytotoxicity against HUVEC at concentrations up to 2500 μg/mL, and do not increase the mortality of HUVEC cells[3].

Carrageenan (1% (w/v); s.c.; plantar region of the left hind paw) at an injection volume of 100 μL induces acute paw edema in male Wistar rats (with the peak edema volume reached 4-5 hours post-injection), while an injection volume of 25 μL induces acute paw edema in male Swiss albino mice[5].
