Anxiolytic drug, Gedocarnil [SH 530, ZK 113315], was undergoing phase I clinical trials with Schering AG in Germany as a potential nootropic agent. However it`s development for the treatment of cognition disorders was discontinued.

Pazufloxacin is a fused tricyclic quinolone derivative that has a broad spectrum of anti-bacterial activity. Pazufloxacin inhibits bot DNA gyrase and topoisomerase IV and has shown in vitro activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Klebsiella, Enterobacter, Hafnia, Citrobacter, Proteus, Providencia, Serratia, Shigella, Salmonella, Aeromonas and Yersinia. The drug is used for the treatment of infectious diseases such as abdominal infections, genital infections, urinary tract infections, respiratory tract infections, etc.

Meticrane is a diuretic. Meticrane is used to treat essential hypertension.

4,5-diphenylimidazole is an antihistaminic and antiallergic drug. It was shown to be an inhibitor of phenytoin p-hydroxylation in rat hepatic microsomes, however 1-imidazoles had higher inhibitory potency observed at submicromolar concentrations.

Tobicillin (TBPC) is an ester derivative of penicillin G. It is a beta-Lactam antibiotic, peptidoglycan biosynthesis inhibitor. TBPC was shown to be the effective antibiotic for the treatment of enterococcicosis in yellowtail.

Bibenzonium is an antitussive agent. Bibenzonium bromide is a cough suppressant which is stated to have a central action.

Biapenem (INN) is a carbapenem antibiotic. It has in vitro activity against anaerobes. Approved in Japan in 2001. Biapenem is a carbopenems antibiotic which suppresses bacterial growth by inhibiting the enzymes responsible for bacterial cell wall synthesis, and shows broad-spectrum antibacterial activity both against gram-positive bacteria and gram-negative bacteria. Biapenem is stable to dehaloperoxidase-I (DHP-I) and can not be administered together with DHP-I inhibitor. This product is applicable to the treatment of a variety of infections caused by sensitive bacteria: septicemia, pneumonia, lung abscess, secondary infections resulting from chronic respiratory disease, cystitis, pyelonephritis, peritonitis, appendagitis, etc. Biapenem is generally well tolerated. The most common adverse events in clinical trials were skin eruptions/rashes, nausea and diarrhoea.

Bevonium is a parasympatolytic antimuscarinic compound. It possesses spasmolytic properties. The use of the drug is discontinued.

Betamipron (BP) is an amino acid derivative that has benzoyl and carboxyl groups in its structure, and it also has very low toxicity in mammals (LD50 in the rat, more than 3,000 mg/kg, i.v.). BP is a renal anionic transport inhibitor and decreases nephrotoxicity caused by high doses of carbapenems, anionic drugs, by inhibiting the drug accumulation in the renal cortex. BP significantly inhibited organic anion uptake by human organic anion transporter 1 (human-OAT1) and human-OAT3 in a dose-dependent manner. Panipenem-betamipron is marketed as Carbenin® (Sankyo Company, Tokyo, Japan).
