High penetration comp1ositions (HPCs) or prodrugs (HPPs) of antimicrobials and antimicrobial-related compounds are provided. The HPCs/HPPs are capable of being converted to parent drugs or drug metabolites after crossing the biological barrier and thus can render treatments. Additionally, the HPCs/HPPs are capable of reaching areas that their parent drugs may not be able to access and rendering a sufficient concentration at the target areas and therefore render novel treatments.
