Lindenenol (Linderene) is isolated from Radix linderae and has antioxidant and antibacterial effects.

Mecillinam (Hexacillin), an extended-spectrum penicillin antibiotic, is considered to be active against Gram-negative bacteria by binding specifically to penicillin-binding protein 2 (PBP2). It is used primarily to treat urinary tract infections and has also been used in the treatment of paratyphoid fever and typhoid.

Propargylcholine (Propargylcholine (bromide)) is an alkyne-modified choline analog and inhibits choline catabolism at the level of Dgc enzyme-catalyzed dimethylglycine demethylation in Pseudomonas aeruginosa.

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

Telithromycin (HMR3647) is a ketolide antibiotic to treat community acquired pneumonia of mild to moderate severity. Antibacterial Telithromycin prevents bacteria from growing, by interfering with their protein synthesis. Telithromycin binds to the subunit 50S of the bacterial ribosome, and blocks the progression of the growing polypeptide chain. Telithromycin has over 10 times higher affinity to the subunit 50S than erythromycin. In addition, telithromycin strongly bind simultaneously to two domains of 23S RNA of the 50 S ribosomal subunit, where older macrolides bind strongly only to one domain and weakly to the second domain. Telithromycin can also inhibit the formation of ribosomal subunits 50S and 30S.
