실험 절차

Fortimicin KE may also be obtained by heating Fortimicin D in an alkaline aqueous solution such as sodium hydroxide and barium hydroxide. Specifically, Fortimicin D is heated in an aqueous solution of saturated barium hydroxide at a temperature of 100° C. for 3 hours. Then the reaction solution is neutralized with dry ice and the resulting precipitate of barium carbonate is removed by filtration. The filtrate is concentrated and passed through a column packed with Amberlite CG-50 (ammonium form). After washing the column with water, elution is carried out with 0.2 N aqueous ammonia. First, a small amount of reaction by-products is eluted and subsequently Fortimicin KE is eluted. The fractions containing Fortimicin KE are combined and concentrated under reduced pressure. The concentrate is then freeze-dried to obtain the free base of Fortimicin KE.
