Acting as an analog of the 3' terminal end of aminoacyl-tRNA, puromycin incorporates itself into a growing polypeptide chain and causes its premature termination, thereby inhibiting protein synthesis. This agent has antimicrobial, antitrypanosomal, and antineoplastic properties; it is used as an antibiotic in cell culture."}]
