Armeniaspirol B is a selective antibiotic targeting Gram-positive pathogens, showing MIC values of 0.5 μg/mL against S. aureus Newman and 2.0 μg/mL against S. aureus USA300. Armeniaspirol B is promising for research of Gram-positive bacterial infections (e.g., MRSA, VRE infections).

Cidofovir sodium is an acyclic monophosphate nucleotide analogue and CMV inhibitor with antiviral activity. Cidofovir sodium inhibits cytomegalovirus (CMV) replication by selectively inhibiting viral DNA polymerase. Cidofovir sodium induces apoptosis and can be used in studies of AIDS cytomegalovirus retinitis, herpes, and cancer. Cidofovir sodium also has anti-orthopoxvirus and anti-variola activities.
