Dibekacin is a semisynthetic aminoglycoside antibiotic useful in the treatment of severe gram-negative bacterial infections. The drug is marketed in Japan.

Tilorone (trade names Amixin, Lavomax and others) is the first recognized synthetic, small molecular weight compound that is an orally active interferon inducer. Tilorone induces the formation of interferons (alpha, beta, gamma) by intestinal epithelial cells, hepatocytes, T-lymphocytes, and granulocytes. After ingestion, the maximum production of interferon is determined in the sequence of the intestine - liver - blood after 4-24 hours. Activates the stem cells of the bone marrow, stimulates humoral immunity, increases the production of IgM, IgA, IgG, affects the antibody formation, reduces the degree of immunosuppression, restores the ratio of T-helperers / T-suppressors. The mechanism of antiviral action is associated with the inhibition of translation of virus-specific proteins in infected cells, thereby suppressing the replication of the virus. Effective against influenza viruses and viruses that cause ARVI, hepato- and herpesviruses, incl. CMV and others. The mechanism of antiviral action is associated with the inhibition of translation of virus-specific proteins in infected cells, thereby suppressing the replication of the virus.

Rufloxacin (MF-934) is a fluoroquinolone antibacterial drug. It acts as a DNA gyrase inhibitor. Rufloxacin shows in vitro antibacterial activity against E. coli, Salmonella, Klebsiella, Proteus and Staphylococcus spp. Lower in vitro activity was observed with Pseudomonas, Serratia, Enterobacter and the streptococci group D. Rufloxacin is indicated for the treatment of lower respiratory tract and urinary tract infections caused by germs sensitive to rufloxacin.

Bekanamycin is an aminoglycoside and is a congener of kanamycin. It is given topically as the sulfate for the treatment of eye infections. It is reported to be more toxic than kanamycin A. Antibiotic complex produced by Streptomyces kanamyceticus Okami & Umezawa from Japanese soil. There are no known interactions with other drugs.

Protionamide is a thioamide derivative with antitubercular activity, usually involving to treat MDR TB and leprosy. It has the same active substances and cross-resistance with ethionamide. Prothionamide is part of a group of drugs thioamides. The side effects of prothionamide are similar to ethionamide. Prothionamide is most commonly associated with nausea and vomiting. It may cause depression and hallucinations. Rarely, prothionamide will cause jaundice, menstrual disturbances and peripheral neuropathy. Prothionamide has received approval in Germany for the treatment of TB and drug resistant TB. While prothionamide is widely used to treat MDR TB, there is little published evidence demonstrating safety and efficacy. Protionamide forms a covalent adduct with bacterial nicotinamide adenine dinucleotide (NAD), PTH-NAD, which competitively inhibits 2-trans-enoyl-ACP reductase (inhA), an enzyme essential for mycolic acid synthesis. This results in increased cell wall permeability and decreased resistance against cell injury eventually leading to cell lysis. Mycolic acids, long-chain fatty acids, are essential mycobacterial cell wall components and play a key role in resistance to cell injury and mycobacterial virulence.

Sulfametrole is a sulfonamide antibiotic used typically in combination with trimethoprim. Sulfametrole combined with trimethoprim could provide a choice for difficult-to-treat infections, particularly when administered intravenously. Sulfametrole/trimethoprim is an alternative sulphonamide/trimethoprim combination available in several EU countries, including Austria and the Netherlands. Sulphonamide/trimethoprim combination is the most active antibacterial but sulfametrole and sulfametrole/trimethoprim did not overcome resistance to sulfamethoxazole and sulfamethoxazole/trimethoprim in Enterobacteriaceae.

Sulphathiourea (Badional) is short acting sulfonamide, belongs to antibacterial drugs

Tosufloxacin is a fluoroquinolone antibacterial agent. Tosufloxacin is an inhibitor of bacterial DNA gyrase and topoisomerase IV. Tosufloxacin is indicated for the treatment of various infections such as skin, respiratory, urinary, gynecologic, ophthalmologic, otolaryngologic, dental infections. Fluoroquinolones including tosufloxacin have a potential risk of inducing cartilage and joint toxicity in children. It is also associated with severe thrombocytopenia and nephritis, and hepatotoxicity.

Tetroxoprim is an inhibitor of bacterial dihydrofolate reductase. In combination with sulfadiazine (co-tetroxazine) it has been used for the treatment of susceptible bacterial infections.

FLURITHROMYCIN, an erythromycin fluorine derivative, was isolated from the fermentation broth of Streptomyces erythraeus ATCC 31772. It is used as an antibacterial drug. The spectrum of activity of FLURITHROMYCIN is almost identical to that of erythromycin but it is more stable to acid.
