Mupirocin lithium salt is a carboxylic acid isolated from Pseudomonas fluorescens. When at lower concentrations, it exhibits bacteriostatic properties, while exhibiting bactericidal properties at higher concentrations. It targets gram-positive bacteria such as methicillin-resistant Staphylococcus aureus (MRSA). Mupirocin lithium salt has been used to study mupirocin resistance in Mycoplasma bacteria.

Thiostrepton is a cyclic peptide antibiotic isolated from Streptomyces azureus. It targets a wide variety of gram-negative and gram-positive bacteria, especially those causing skin infections. It has been used as a marker for selection of recombinant Streptomyces cultures. Additionally, thiostrepton has been shown to inhibit FOXM1, a gene commonly overexpressed in cancer cell lines, thus inhibiting cancer cell growth.

Thiostrepton functions by binding elongation factor G (EF-G) and interfering with ribosomal GTPase activity, ultimately inhibiting protein synthesis.

Tiamulin fumarate is a pleuromutilin antibiotic targeting gram-positive bacteria and several Mycoplasma species. It is soluble in aqueous solution.

Pleuromutilin antibiotics target the 50s ribosomal subunit, inhibiting protein synthesis in bacteria, by binding peptidyl transferase. This blocks formation of peptide bonds.

Trimethoprim is a bactericidal antibiotic effective against bacteria responsible for urinary tract infections, prostatitis, and cystitis. It is commonly combined with sulfamethoxazole to combat Staphylococcus aureus.

Trimethoprim is a bactericidal antibiotic effective against bacteria responsible for urinary tract infections, prostatitis, and cystitis. It is commonly combined with sulfamethoxazole to combat Staphylococcus aureus. Trimethoprim lactate is a freely soluble form of trimethoprim. GoldBio also offers Trimethoprim, which contains only the pure active ingredient, but is also less soluble.

Valnemulin is a pleuromutilin antibiotic targeting Mycoplasma bacteria, especially those responsible for bovine respiratory infections. It is freely soluble in aqueous solution.

Valnemulin's mechanism of action involves its inhibition of protein synthesis in bacteria by binding the peptidyl transferase enzyme in the 50s ribosomal subunit.
