Nifuraldezone is an antibacterial compound. It completely mimics the radiosensitizing effect of molecular oxygen in hypoxic mammalian cells in vitro at concentrations in tissue culture medium which showed no measurable acute toxicity.

Thiphencillin is a penicillin analog patented by Abbott Laboratories as an antibacterial agent. Thiphencillin shows potent antibacterial activity against various species and genera of pathogenic bacteria.

Acedapsone (4,4′-diacetyldiaminodiphenyl sulfone) is a long-acting intramuscular repository derivative of dapsone. Acedapsone is mainly used as a depot leprostatic agent. The parent compound possesses little activity against M. leprae but is metabolized into active dapsone. Its half-life is 46 days, and that of the derived dapsone is 43 days. A 300-mg intramuscular dose maintains dapsone levels in volunteers above the inhibitory concentration for M. leprae for approximately 100 days. Microbiologic and clinical responses are somewhat slower than those for daily dapsone are. Long-term studies with acedapsone by injection five times yearly have yielded encouraging results. Acedapsone shows promise especially in regions where, or in patients in whom, long-term oral therapy is not practical.

Pentalamide (also known as O-pentylsalicylamide) was developed as an antifungal agent for topical applications. Information about the current use of this drug is not available.

Nifurquinazol, a 5-nitrofuran derivative, is an antibacterial agent.

Gentamicin C2 together with epimer C2a is a part of the antibiotic of the aminoglycoside group, gentamicin. Gentamicin C2 has a methyl group in the 6′ position. Gentamicin is a broad-spectrum antibiotic that binds to the prokaryotic ribosome, inhibiting protein synthesis in susceptible bacteria. Gentamicin is bactericidal in vitro against Gram-positive and Gram-negative bacteria.
