| amikacin | An amino cyclitol glycoside that is kanamycin A acylated at the N-1 position by a 4-amino-2-hydroxybutyryl group. | amikacin |
| etimicin | An aminoglycoside antibiotic that is gentamycin C1a in which the hydrogen of the amino group at position 1 is substituted by an ethyl group. It is a fourth generation semisynthetic aminoglycoside that has antimicrobial activity against both gram-positive and gram-negative bacterial infections and also effective against aminoglycoside resistant strains. | etimicin |
| fortimicin a | An amino cyclitol glycoside that is L-chiro-inositol in which the hydroxy groups at positions 1, 4, and 6 are replaced by aminoacetyl)methylamino, amino, and methoxy groups, respectively, and in which the hydroxy group at position 3 is converted to the corresponding 2,6-diamino-2,3,4,6,7-pentadeoxy-beta-L-lyxo-heptopyranoside. The major component of fortimicin, obtained from Micromonospora olivasterospora. It is administered (as the sulfate salt) by intramuscular injection or intravenous infusion for the treatment of severe systemic infections due to sensitive Gram-negative organisms. | astromicin |
| paromomycin | An amino cyclitol glycoside that is the 1-O-(2-amino-2-deoxy-alpha-D-glucopyranoside) and the 3-O-(2,6-diamino-2,6-dideoxy-beta-L-idopyranosyl)-beta-D-ribofuranoside of 4,6-diamino-2,3-dihydroxycyclohexane (the 1R,2R,3S,4R,6S diastereoisomer). It is obtained from various Streptomyces species. A broad-spectrum antibiotic, it is used (generally as the sulfate salt) for the treatment of acute and chronic intestinal protozoal infections, but is not effective for extraintestinal protozoal infections. It is also used as a therapeutic against visceral leishmaniasis. | paromomycin |
| ribostamycin | An amino cyclitol glycoside that is 4,6-diaminocyclohexane-1,2,3-triol having a 2,6-diamino-2,6-dideoxy-alpha-D-glucosyl residue attached at position 1 and a beta-D-ribosyl residue attached at position 2. It is an antibiotic produced by Streptomyces ribosidificus (formerly S. thermoflavus). | ribostamycin |
| sisomicin | | sisomycin |
| tobramycin | A amino cyclitol glycoside that is kanamycin B lacking the 3-hydroxy substituent from the 2,6-diaminoglucose ring. | tobramycin |
