Legionella Infection

Swertianolin is a xanthone glycoside. Swertianolin can be isolated from plants of the Gentianaceae family (e.g., Gentiana campestris and Swertia punicea). Swertianolin inhibits p38 phosphorylation and NF-κB activation, and reduces NO and ROS production. Swertianolin exhibits anti-Helicobacter pylori activity with an IC₅₀ of 6.1 μM and a minimum bactericidal concentration of 91.7 μM. Swertianolin modulates immune function in sepsis. Swertianolin is useful in the research of diseases such as Alzheimer's disease, hepatitis B, Helicobacter pylori infection, and sepsis.

Cefetamet pivoxyl (Ro 15-8075 free base) is an orally active cephalosporin Antibiotic and a prodrug of Cefetamet (HY-A0111). After ingestion, Cefetamet pivoxyl is hydrolyzed by gastrointestinal esterases to form Cefetamet. Cefetamet pivoxyl is primarily active against aerobic Gram-negative bacteria (such as Enterobacteriaceae, Neisseria, Haemophilus) and some Gram-positive bacteria (such as non-enterococcal streptococci). Cefetamet pivoxyl exhibits potent in vivo antibacterial activity against strains of Gram-positive bacteria (S. pyogenes) and Gram-negative bacteria (E. coli, K. pneumoniae, S. marcescens, P. vulgaris, P. mirabilis, H. influenzae).
