CG anti-respiratory virus activities in vivo animal studies. (MDCK cells, Madin–Darby canine kidney cells; PMN, polymorphonuclear leukocytes; BID, twice a day; RSV, respiratory syncytial virus).
CG Type | Virus Type | Experimental Model | Dose | Antiviral Assay | Effects | Ref |
---|---|---|---|---|---|---|
Type II CG | Influenza virus H1N1 (A/PR/8/34) | BALB/c mice intranasal infection | 1 mg/mL | Virus titration with MDCK cells | Depleted macrophages and increased PMN in the blood, enhancement of viral titer | [100] |
Type II CG | Influenza virus H1N1 (A/PR/8/34) | BALB/c mice intranasal infection | 200 mg/kg | Virus titration with MDCK cells | Depleted macrophages, phagocytes, and monocytes | [102] |
ι-CG | Influenza virus strain H1N1 (A/PR8/34) and the formerly pandemic H3N2 (A/Aichi/2/68) | C57Bl/6 mice intranasal infection | 60 µg BID for 15 days | PFU | Reduced viral titers and increased survival (40%) | [96] |
κ-CG (low MW) | Mouse adapted influenza virus A/FM/1/47(H1N1) | ICR mice with nasal drip | 40 µL of 1.5 mg/mL for 7 days | Measure pulmonary edema index | Inhibition of pulmonary edema in mice | [101] |
κ/ι-CG and zanamivir | Influenza A virus H1N1(09)pdm, H3N2, H5N1, and H7N7 | C57BL/6 mice with intranasal injection | 50 µL of 1.2 and 0.4 mg/mL stock BID for 5 days | Survival and weight loss, necropsy, and inflammation | Increased survival, decreased weight loss, reduced necropsy, and inflammation | [98] |
