Abstract
Resistance to aminoglycoside antibiotics has had a profound impact on clinical practice. Despite their powerful bactericidal activity, aminoglycosides were one of the first groups of antibiotics to meet the challenge of resistance. The most prevalent source of clinically relevant resistance against these therapeutics is conferred by the enzymatic modification of the antibiotic. Therefore, a deeper knowledge of the aminoglycoside-modifying enzymes and their interactions with the antibiotics and solvent is of paramount importance in order to facilitate the design of more effective and potent inhibitors and/or novel semisynthetic aminoglycosides that are not susceptible to modifying enzymes.

Abstract
Novel fungicides are urgently needed. It was recently reported that the attachment of an octyl group at the O-4″ position of kanamycin B converts this antibacterial aminoglycoside into a novel antifungal agent. To elucidate the structure-activity relationship (SAR) for this phenomenon, a lead compound FG03 with a hydroxyl group replacing the 3″-NH2 group of kanamycin B was synthesized. FG03's antifungal activity and synthetic scheme inspired the synthesis of a library of kanamycin B analogues alkylated at various hydroxyl groups. SAR studies of the library revealed that for antifungal activity the O-4″ position is the optimal site for attaching a linear alkyl chain and that the 3″-NH2 and 6″-OH groups of the kanamycin B parent molecule are not essential for antifungal activity. The discovery of lead compound, FG03, is an example of reviving clinically obsolete drugs like kanamycin by simple chemical modification and an alternative strategy for discovering novel antimicrobials.

Abstract
The attachment of alkyl and other hydrophobic groups to traditional antibacterial kanamycins and neomycins creates amphiphilic aminoglycosides with altered antimicrobial properties. In this review, we summarize the discovery of amphiphilic kanamycins that are antifungal, but not antibacterial, and that inhibit the growth of fungi by perturbation of plasma membrane functions. With low toxicities against plant and mammalian cells, they appear to specifically target the fungal plasma membrane. These new antifungal agents offer new options for fighting fungal pathogens and are examples of reviving old drugs to confront new therapeutic challenges.

Abstract
Deoxygenation of the diol groups in rings A and D of neomycin in combination with the introduction of an N1-(l)-HABA group in the 2-deoxystreptamine subunit (ring B) leads to a novel and potent antibiotic (1) with activity against strains of S. aureus carrying known aminoglycoside resistance determinants, as well as against an extended panel of Methicillin-resistant S. aureus isolates (n = 50). Antibiotic 1 displayed >64 fold improvement in MIC50 and MIC90 against this MRSA collection when compared to the clinically relevant aminoglycosides amikacin and gentamicin. The synthesis was achieved in six steps and 15% overall yield.
