Thiostrepton is a natural antibiotic produced by bacteria of Streptomyces genus. Thiostrepton has been used in veterinary medicine in mastitis caused by gram-negative organisms and in dermatologic disorders. It is mostly used in complex ointments containing neomycin, nystatin, Thiostrepton and topical steroids. It is also active against gram-positive bacteria. It is notable that ointments for human usage contain neomycin, nystatin, and topical steroids, but no Thiostrepton. It can induce apoptotic cell death in human cancer cells. Thiostrepton was reported (in 2008) to exhibit activity against breast cancer cells through targeting the transcription factor forkhead box M1 (FOXM1). It has also been shown to circumvent acquired cisplatin resistance in breast cancer cells under in invitro conditions. Thiostrepton is used in molecular biology as a reagent for both positive and negative selection of genes involved in nucleotide metabolism. It is protein synthesis inhibitor.

Miripirium chloride is used as an antimicrobial preservative in some pharmaceutical products. Miripirium was used as the preservative in Depo-Medrol. Miripirium was used as constituent of methylprednisolone acetate suspensions used for intra-articular corticosteroid therapy.
Isoflupredone is a veterinary drug used in cows, pigs and horses for the treatment of wide range of conditions: ketosis, musculoskeletal disorders, hypersensitivity, infections, inflammatory diseases, etc. The drug belongs to the class of corticosteroids and exerts its therapeutic effect by binding to glucocorticoid and mineralocorticoid receptors of animals.

Framycetin is a component of neomycin that is produced by Streptomyces fradiae. Framycetin is used for the treatment of bacterial eye infections such as conjunctivitis. Framycetin is an antibiotic. It is not active against fungi, viruses and most kinds of anaerobic bacteria. Framycetin works by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Framycetin is useful primarily in infections involving aerobic bacteria bacteria. Framycetin binds to specific 30S-subunit proteins and 16S rRNA, four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex, misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes. Framycetin is a component of SOFRACORT (Framycetin sulphate - Gramicidin-dexamethasone), indicated for the treatment of blepharitis and infected eczema of the eyelid; allergic, infective and rosacea conjunctivitis; rosacea keratitis; scleritis and episcleritis; iridocyclitis, and other inflammatory conditions of the anterior segment of the eye, as well as otitis externa (acute and chronic) and other inflammatory and sebhorrheic conditions of the external ear.

Polymyxin B is a lipopeptide antibiotic isolated from Bacillus polymyxa. Its basic structure consists of a polycationic peptide ring and a tripeptide side chain with a fatty acid tail. Polymyxin B is a mixture of at least four closely related components, polymyxin B1 to B4, with polymyxin B1 and B2 being the two major components. Polymyxin B acts on Gram-negative bacteria by interacting with lipopolysaccharide (LPS) of the outer membrane and destabilizing it. Polymyxin B is indicated for the treatment of many bacterial diseases such as meningeal infections, urinary tract infections and bacteremia.

Bacitracin is a polypeptide antibiotic produced by Bacillus subtilis and Bacillus licheniformis. Bacitracin in combination with neomycin and polymyxin B is indicated for the treatment of many bacterial diseases. The antibacterial properties of bacitracin are mediated by its binding to C55-isoprenyl pyrophosphate, resulting in inhibition of cell wall biosynthesis.
