Description: Iclaprim, also known as AR-100; RO-48-2622; AR-100.001; RO-482622, is a diaminopyrimidine dihydrofolate reductase (DHFR)-inhibiting extended-spectrum antibiotic active against gram positive organisms being developed for the treatment of complicated skin and soft tissue infections caused by antibiotic-resistant bacteria. It is structurally related to trimethoprim. In vitro, iclaprim is highly active against MRSA, vancomycin-resistant Staphylococcus aureus (VRSA), strains of Streptococcus pneumoniae resistant to several common antibiotics, and some Gram-negative bacteria.
