Trovafloxacin, a broad-spectrum quinolone antibiotic, exhibits potent activity against Gram-positive bacteria.

Trovafloxacin is a broad-spectrum fluoroquinolone antibiotic that inhibits the activity of DNA gyrase and topoisomerase IV, enzymes involved in DNA replication. It also acts as an effective and specific inhibitor of the pannexin 1 channel (PANX1, IC50 = 4 μM).

Clometocillin is a penicillin that can active penicillin to pen-I or pen-R pneumococci.

Diphenicillin (Ancillin (free acid); 2-Biphenylyl penicillin (free acid); SKF-12141 (free acid)) is a penicillin that resists Penicillinase and exhibits antibacterial activity. It shows effective activity against Gram-positive cocci. Diphenicillin is promising for research on infectious diseases caused by Gram-positive bacteria such as staphylococci, pneumococci, and group A streptococci.
