parainfluenza-3 virus

T-1105 is a broad-spectrum antiviral inhibitor.

Betamethasone 21-phosphate is a synthetic glucocorticoid.1It prevents increases in macrophage and eosinophil numbers in bronchoalveolar lavage fluid (BALF) and decreases in blood leukocyte numbers in a guinea pig model of parainfluenza-3 viral infection when administered at a dose of 8 mg/kg but does not prevent airway hyperresponsiveness after infection.2Betamethasone 21-phosphate inhibits cell infiltration into the aqueous humor in a rat model of endotoxin-induced uveitis when administered topically or subcutaneously at doses of 0.01-1% or 1 mg/kg, respectively.3It increases maximal lung pressure volume curves in fetal sheep when administered to pregnant ewes at 0.75 gestation at doses of 80 and 170 μg/kg.1Betamethasone 21-phosphate increases body weight, impairs learning and memory, increases anxiolytic behavior, and reduces hippocampal neurogenesis in CD-1 mice but reduces body weight and increases neurogenesis with no effect on anxiety in high-anxiety DBA/2 mice when administered at a dose of approximately 25 mg/kg per day in the drinking water for seven weeks.4Formulations containing betamethasone 12-phosphate and betamethasone acetate have been used in the treatment of severe allergic conditions and a variety of immune-related conditions. 1.Loehle, M., Schwab, M., Kadner, S., et al.Dose-response effects of betamethasone on maturation of the fetal sheep lungAm.

RNase L-IN-2 is an activator of RNase L with EC50 of 22 uM; shows broad-spectrum antiviral activity against diverse types of RNA viruses, including the human pathogen human parainfluenza virus type 3, with no cytotoxic at the effective concentrations.

Ligustroside shows little antioxidant, and anti-inflammatory properties, it shows a significant inhibition effect on prostaglandin E2 (PGE2)-release. Ligustroside shows moderate antiviral activities against parainfluenza type 3 virus.
