Fandofloxacin is a difluoroquinolone derivative. This compound possesses an antibacterial spectrum comparable to those of rufloxacin and ciprofloxacin in vivo. Fandofloxacin showed a rapid and nearly complete absorption, and a long residence time in the body. Because it has been reported that the in vivo antibacterial activity of Fandofloxacin is comparable or superior to other quinolones, despite the fact that its in vitro activity is significantly lower than that of the other compounds, the pharmacokinetics of this antibiotic may be responsible, at least in part, for the enhanced in vivo antibacterial activity of Fandofloxacin. Fandofloxacin is an inhibitor of bacterial DNA gyrase. The toxicities and adverse effects of Fandofloxacin observed in various toxicology studies and clinical trials were less than those of commercially available drugs. It has been in phase II clinical trial for the treatment of Urinary tract infections. However, this research has been discontinued in 2008.

Entospletinib (GS-9973) is an adenosine triphosphate competitive inhibitor of Syk that disrupts kinase activity, which is currently in clinical trials for multiple B-cell malignancies. The most common treatment-emergent serious adverse events included dyspnea, pneumonia, febrile neutropenia, dehydration, and pyrexia.

Dimecamine is ganglion blocking agent. A slowly developing but moderate contracture of the chick biventer cervicis muscle was observed with 5x10-4M-dimecamine methiodide solution. A small reduction in the twitch response was also observed. Similar concentrations of dimecamine and pempidine produced only slowly developing and very small contractures. Dimecamine differs in neuromuscular-blocking activity from its corresponding quaternary metho-salts by a factor of less than two.

Imazapic is a selective herbicide for both the pre- and post-emergent control of some annual and perennial grasses and some broadleaf weeds. Imazapic kills plants by inhibiting the production of branched chain amino acids, which are necessary for protein synthesis and cell growth. It has been useful for weed control in natural areas, particularly in conjunction with the establishment of native warm-season prairie grasses and certain legumes. Imazapic is relatively non-toxic to terrestrial and aquatic mammals, birds, and amphibians. It has a low level of toxicity to birds but is more toxic to aquatic life and honey bees. It has a high potential for bioaccumulation. Imazapic has an average half-life of 120 days in soil. It is may be persistent in soil systems but usually degrades quickly in aquatic systems via photolysis. It has a high aqueous solubility, is volatile and, based on its chemical properties, is moderately mobile and may leach to groundwater.

Tryparsamide is an arsenic compound with activity against Spirochaetes bacteria. Tryparsamide is used in the treatment of syphilis and African sleeping sickness. For decades Tryparsamide remained the standard treatment for trypanosomiasis. Tryparsamide has two remarkable properties: first, it increases the resistance of the individual by improving his general physical status; and, second, the high penetrability for nervous tissue which it possesses may increase the potential spirocheticidal action of the drug.

S-(+)-niguldipine is a more active enantiomer and is a selective antagonist for the and α1A-adrenoceptor. In addition, it can be used for discriminating of alpha 1A- from alpha 1B-adrenoceptors. There were made attempts to investigate the antidepressant action of S-(+)-niguldipine on rats, but that studies were unsuccessful.

Pranolium (UM-272) is propranolol derivative. It can reduce the extent of myocardial injury sustained during severe ischemia. UM-272 lacks significant beta-adrenergic blocking activity but retains the negative chronotropic, negative inotropic and antiarrhythmic effects common to both d- and l-propranolol. The protective effects of UM-272 during myocardial ischemia cannot be due to metabolic effects of the beta-adrenergic blockade but may be due to effects on oxygen consumption or to effects on myocardial membrane properties that are related to its antiarrhythmic and myocardial depressant activity. The ability of UM-272 to enhance blood flow to subendocardial myocardium may also play a role in its beneficial effects during ischemia. UM-272 may protect the ischemic heart through direct effects on myocardial Ca++ regulating mechanisms. UM-272 has kinetically similar use-dependent inhibitory action of the fast sodium channels of cardiac muscles as other Class Ia antiarrhythmic drugs like quinidine or procainamide. Pranolium was investigated as an antiarrhythmic agent.
