Abstract:
On the occasion of the 60th anniversary of the discovery (1957) of kanamycin (KM), a series of research achievements on KM and its semisynthetic derivative Arbekacin (ABK) are outlined. KM was first used clinically in 1958 and was appreciated for its remarkable curing effect on various bacterial infections, especially tuberculosis. ABK is a KM derivative rationally semisynthesized to overcome KM resistance due to enzymatic phosphorylation and acetylation. Since its approval in 1990 as an anti-MRSA drug, ABK has been and still is effectively used in chemotherapy because MRSA rarely develops high ABK-resistance. Research that illuminated the unique features of ABK enabling it to resist the development of resistance by MRSA are also described.
