使用
Antibiotic complex produced by Streptomyces kanamyceticus Okami & Umezawa from Japanese soil. Comprised of three components, kanamycin A, the major component, and kanamycins B and C, two minor congeners. Antibacterial.
純化方法
A small quantity of kanamycin B (24mg) can be purified on a small Dowex-1 x 2 column (6 x 50mm); the required fraction is evaporated to dryness and the residue crystallised from EtOH containing a small amount of H2O. [Umezawa et al. Bull Chem Soc Jpn 42 537 1969.] It has been crystallised from H2O by dissolving ~1g in H2O (3mL), adding Me2NCHO (3mL) and setting aside at 4o overnight. The needles are collected and dried to constant weight at 130o. It has also been recrystallised from aqueous EtOH. It is slightly soluble in CHCl3 and isoPrOH. [IR: Wakazawa et al.
