Cefpimizole is an antibiotic of broad spectrum developed in Japan for the treatment of such conditions as uncomplicated gonorrhea and gynecologic infections. The drug was tested in clinical trials, however, its development was terminated.

Bunamidine is a anti-parasitic drug, which was approved by FDA for the treatment of tapeworms in cats and dogs (Scolaban 400 tablets).

Dequalinium is a quaternary ammonium cation commonly available as the dichloride salt. Dequalinium chloride has an antiseptic effect against a wide range of bacteria, yeasts, and some fungi and viruses. It kills the micro-organisms associated with various mild infections of the mouth and throat. Also, Dequalinium chloride is active against the bacteria which cause bacterial vaginosis. Dequalinium Chloride (DECA) is a PKC inhibitor and high-affinity blocker CNGA1 channel, and nearly as effective on heteromeric CNGA1+CNGB1 channels. Common side effects are: vaginal discharge; vaginal itching or vaginal burning; vaginal yeast infection (thrush); tender tongue.

Apalcillin is a naphthydridine derivative of ampicillin. Apalcillin has a broad spectrum of antibacterial activity that is very similar to that of piperacillin, except that apalcillin is significantly more active against Pseudomonas aeruginosa and Acinetobacter spp. Against Acinetobacter spp., apalcillin is uniquely active, compared to the other penicillins and comparison drugs. Strains producing high amounts of β-lactamases do become resistant to apalcillin. PAH (p-aminohippurate) clearance was significantly decreased during apalcillin infusion. Apalcillin appeared to compete with PAH for proximal tubular secretion but induced no further renal dysfunction.

Clamoxyquin is an antiamebic and antidiarrheal agent. Clamoxyquin is usually used as the pamoate or hydrochloride salt. It is a veterinary antiparasitic drug used to treat salmonids for the myxozoan parasite Myxobolus cerebralis. Dietary inclusion of several anti-coccidial drugs, including clamoxyquin, proguanil and fumagillin, has been found effective against myxozoan infections in finfish.

Clevudine (also known as L-FMAU) is a nucleos(t)ide reverse transcriptase inhibitor, which inhibits the DNA synthesis activity of the hepatitis B virus polymerase. The drug was approved in Korea and Philippines and is being marketed under the names Levovir and Revovir. The drug is indicated in patients with chronic hepatitis B virus infection. Upon administration, clevudine is metabolized to the active metabolite, clevudine triphosphate, which is responsible for the inhibition of viral polymerase.

Cefsulodin is a third-generation of cephalosporin antibiotic with a narrow spectrum of activity. It has a specific activity against Pseudomonas aeruginosa. Cefsulodin’s targets are bacterial penicillin binding proteins. Drug is indicated for the treatment of infections of lower respiratory tract, skin and skin structures, urinary tract, bone and joint; treatment of gynecological infections; treatment of intra-abdominal infections; treatment of septicemia and CNS infections including meningitis caused by susceptible strains of specific microorganisms. Cefsulodin appears to be well tolerated and relatively free of any significant toxicity except for nausea and vomiting.

Dequalinium chloride has an antiseptic effect against a wide range of bacteria, yeasts, and some fungi and viruses. It kills the micro-organisms associated with various mild infections of the mouth and throat. Also, Dequalinium chloride is active against the bacteria which cause bacterial vaginosis. Dequalinium Chloride (DECA) is a PKC inhibitor and high-affinity blocker CNGA1 channel, and nearly as effective on heteromeric CNGA1+CNGB1 channels. Common side effects are: vaginal discharge; vaginal itching or vaginal burning; vaginal yeast infection (thrush); tender tongue.

Astromicin is an aminoglycoside antibiotic produced by Micromonospora spp. It is effective against major gram-negative bacterias such as Proteus, Serratia, Citrobacter, Enterobacter spp., Klebsiella, Escherichia coli and Staphylococcus aureus. Astromicin sulfate has been given by intramuscular injection or intravenous infusion. Side effects are: rash, urticaria, itch, erythema, fever, nausea, vomiting, and diarrhea. Combination with strong diuretics can cause nephrotoxicity and ototoxicity.

Cefprozil is a 2nd generation cephalosporin that is FDA approved for the treatment of mild to moderate infections of upper respiratory tract, lower respiratory tract, and uncomplicated skin and skin-structure infections. Cefprozil, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Common adverse reactions include diarrhea, nausea, vomiting, dizziness, abdominal pain and vaginitis. Nephrotoxicity has been reported following concomitant administration of aminoglycoside antibiotics and cephalosporin antibiotics. Concomitant administration of probenecid doubled the AUC for cefprozil.
