Puromycin is an antitumor antibiotic that uses early protein chain termination to induce cell death and has the potential to prove useful in the treatment of infections like multidrug resistant staphylococcus aureus (MRSA). However, a major drawback of puromycin is its metabolism to the nephrotoxic compound puromycin aminonucleoside (PAN).

To solve such issue, we designed and synthesized analogs that are equally or more active against different microorganisms, nonnephrotoxic, and chemically stable. This poster describes the synthesis of a promising new puromycin analog with antimicrobial activity against both Gram-positive and Gram-negative strains of clinical interest. Updated structure-activity relationships for modified puromycin-based molecules will also be presented.

Key Words: puromycin, nucleoside, antimicrobial
