Nitroclofene is an anthelminthic drug. Nitroclofene is a selective inhibitor of the fumarate reductase system of the adult liver fluke at a concentration of 4 umol/L. The enzyme plays an important role in the process of energy utilization. Consequently, it possesses good flukicidal activity against both Fasciola hepatica and F. gigantica.

Cicliomenol is iodo-substituted cyclohexyl phenol derivative patented used as a topical antiseptic. Cicliomenol is often included in preparations intended for the topical treatment of mouth and throat infections.

Cefcanel is a semisynthetic third-generation cephalosporin with antibacterial activity. Cefcanel is active against the species E. coli, K. aerogenes and Proteus mirabilis; H. influenzae and M. catarrhalis has reasonable susceptibility. Cefcanel inhibits 90% of S. aureus strains at 2 µg/ml, irrespective of the presence of a β-lactamase. Cefcanel binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Sovaprevir (formerly ACH-1625) is an oral, once-daily, small molecule inhibitor of HCV protease being developed by Achillion Pharmaceuticals for the treatment of Hepatitis C. ACH-1625 is a linear peptidomimetic inhibitor that non-covalently binds to HCV NS3 protease with high potency and specificity. Short-term monotherapy of HCV genotype-1 infection with ACH-1625 was found to be safe and resulted in ≥3.3 log(10) IU/ml mean viral load reduction. Sovaprevir was developed as a therapy for patients with chronic HCV. Approximately 550 patients already have been treated with the drug in two phase 2 studies with 12-week treatment programs. One study included treatment with sovaprevir combined with pegylated interferon and ribavirin, and the other monitored the use of sovaprevir in combination with ACH-3102, Achillions second-generation NS5A inhibitor. In the second study, all of the patients with HCV genotype 1b achieved sustained virologic response.

Vapendavir (BTA-798) is an orally active capsid-binding inhibitor. It is a potent, orally bioavailable, broad spectrum inhibitor of the large group of HRVs. Vapendavir binds tightly to VP1s canyon and disrupts the ability of the capsid to bind to a specific cell surface receptor. This further inhibits the release of the viral RNA into the cell cytoplasm during the viral uncoating process (removing the lipid bilayer), thereby disrupting viral replication. Vapendavir is designed to be dosed orally. Vapendavir is in phase II clinical trials for the treatment of rhinovirus-induced aggravation of pre-existing asthma or COPD. Vapendavir has shown significant results in proof-of-concept studies. Thus far, from the Phase 1/2 studies conducted, vapendavir has demonstrated a desirable clinical pharmacology profile with high bioavailability, linear pharmacokinetic profile, remained unaffected by concomitant medications, and was not exclusively metabolized.

Palinavir (formerly BILA2011BS) is a potent inhibitor of the human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) proteases and was studied for the treatment of HIV infections. However, information about the current development of this drug is not available.

Temodox is an antibacterial agent that was studied as a veterinary growth stimulant. Information about the current use of this compound is not available.

Ciadox is Quinoxaline 1,4-dioxide derivative with antimicrobial and promoting activities. Cyadox supplied as premix in the final feed in Eastern Europe and may be used in pigs up to four months of age. Some evidence demonstrated that the mechanism of Ciadox for improving pig growth performance was correlated with several metabolic hormones and growth factors. Cyadox also did not show any adverse effects in carcinogenicity tests with rats and long-term toxicity tests with mice and rats. Cyadox subchronic oral toxicity evaluation shows mild toxicity in non-rodents animals. Metabolic transformation of Ciadox leads to three major metabolites, including 1,4-bisdesoxycyadox, 4-desoxycyadox, and quinoxaline-2-carboxylic acid. Ciadox and metabolites shows virtually no toxic effects in the acute and subchronic oral toxicity study and no mutagenic, carcinogenic activivt.

Fumoxicillin was developed as an antibacterial agent that binds to penicillin-binding protein and inhibits the bacterial cell wall biosynthesis. Information about the current development of this compound is not available.

FLOPRISTIN is one of the components of the experimental drug NXL103 (XRP 2868), along with linopristin. Both are semi-synthetic streptogramin antibiotics derived from the Streptomyces genus. NXL103 has a spectrum of antibacterial activity that indicates it has the potential to be effective in the treatment of skin and skin structure infections, including those caused by methicillin-resistant Staphylococcus aureus, as well as community-acquired pneumonia. NXL103 has completed Phase II trials.
