bacterial ribosome

Anisomycin (NSC-76712) is an antibiotic isolated from various Streptomyces species. It interferes with protein and DNA synthesis by inhibiting peptidyl transferase or the 80S ribosome system.

Fusidic acid (Fusidine) is an antibiotic isolated from the fermentation broth of Fusidium coccineum.

Fusidic acid sodium salt (SQ-16360) is a sodium salt form of fusidic acid, a bacteriostatic antibiotic derived from the fungus Fusidium coccineum and used as a topical medication to treat skin infections.

Spectinomycin dihydrochloride (Actinospectacin) is an antibiotic produced by Streptomyces spectabilis. It is active against gram-negative bacteria and used for the treatment of gonorrhea.

Tetracycline hydrochloride (NCI-c55561) is the hydrochloride salt of the tetracycline, a broad-spectrum naphthacene antibiotic produced semisynthetically from chlortetracycline, an antibiotic isolated from the bacterium Streptomyces aureofaciens. In bacteria, tetracycline blocks binding of aminoacyl-tRNA to the mRNA-ribosome complex, thereby inhibiting protein synthesis and bacterial cell growth. Because naturally, fluorescing tetracycline binds to a newly formed bone at the bone/osteoid interface, tetracycline-labeling of bone and fluorescence microscopy may be used to perform bone histomorphometry.

Pristinamycin IA (Mikamycin B) is a substrate for the P-glycoprotein and a cyclo-peptidic macrolactone antibiotic.

Clindamycin (Sobelin) dissociates peptidyl-tRNA from the bacterial ribosome, thereby disrupting bacterial protein synthesis. Clindamycin is a semisynthetic broad-spectrum antibiotic produced by chemical modification of the parent compound lincomycin.

Levomecol, a broad-spectrum antibiotic derived from Streptomyces venezuelae, comprises Chloramphenicol and Methyluracil. It exerts its bacteriostatic effect by binding to the bacterial ribosome, inhibiting protein synthesis by blocking peptidyl transferase.
