Abstract

Kanamycin, an antibiotic complex produced by Streptomyces kanamycetius isolated from Japanese soil, was described by Okami and Umezawa as early as 1957 and consists of three components: Kanamycin A (the major component), B, and C. The disulfate salt of kanamycin A [4-O-(6-amino-6-deoxy-α-d-glucopyranosyl)-6-O-(3-amino-3-deoxy-α-d-glucopyranosyl)-2-deoxystreptamine] is a broad-spectrum antibiotic that is used to treat gonorrhea, salmonella, tuberculosis, and many other diseases. Crystals of kanamycin A monosulfate monohydrate obtained from water are triclinic, space group P1, with a = 7.2294(14), b = 12.4922(15), c = 7.1168(9), α = 94.74(1), β = 89.16(1), γ = 91.59(1), V = 640.2(2) Å3, μ(Cu Kα) = 18.4 cm-1, FW 600.6, Dcalc = 1.558 g/cm3, CAD-4 diffractometric data (2693 reflections, 2554 ≥ 3σ(I)), structure by shelx-86 and refined by full-matrix least squares to a final R value of 0.038. The wrong conformer had an R value of 0.043. Both of the d-glucose moieties are attached to the deoxystreptamine by α linkages. This absolute configuration agrees with the earlier determination by both chemical and X-ray methods with photographic data. The (φ{symbol}, ψ) values for the glycosidic linkages are 101.6°, -121.1°, 106.3°, and -140.4°, respectively. Kanamycin interacts with the ribosomal S12 protein to stabilize the codon-anticodon binding between mRNA and the aminoacyl tRNA and inhibits the elongation of peptide chains through a series of reactions resulting in the prevention of ribosomes from moving along mRNA.{A figure is presented}.
