阿贝卡星, Arbekacin

Inhibitor of DNA replication; aminoglycoside class.

Arbekacin is a semisynthetic aminoglycoside antibiotic derived from dibekacin with activity against both gram-positive and gram-negative bacteria. Arbekacin is most commonly used in the treatment of multi-resistant bacterial infections.

Arbekacin, also known as ABK or arbekacin sulfATE, belongs to the class of organic compounds known as 4, 6-disubstituted 2-deoxystreptamines. These are 2-deoxystreptamine aminoglycosides that are glycosidically linked to a pyranose of furanose unit at the C4- and C6-positions. Arbekacin exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Arbekacin has been detected in multiple biofluids, such as urine and blood. Within the cell, arbekacin is primarily located in the cytoplasm. In humans, arbekacin is involved in the arbekacin action pathway.

Arbekacin is a kanamycin that is kanamycin B bearing an N-(2S)-4-amino-2-hydroxybutyryl group on the aminocyclitol ring. It has a role as an antimicrobial agent, a protein synthesis inhibitor, an antibacterial agent and an antibacterial drug. It is a member of kanamycins and an aminoglycoside. It derives from a kanamycin B.
