This invention relates to a process for preparing 2'-hydroxy- 2'-desamino-4,6-di-0-(aminoglycosyl) -1,3-diaminocyclitols having a 6'-amino function and pharmaceutically acceptable acid addition salts thereof, to novel compounds and salts obtained by this process; and to novel antibacterially active compositions comprising such novel compounds or salts.
The process comprises reacting the corresponding N-protected (except the 2'-amino)-4,6- di-0- (aminoglycosyl)-1,3-diaminocyclitol with hydrogen peroxide in the presence of tungstate ion, followed by cleavage of the thereby formed 2'-oximino derivative and by reduction of the resulting 2'-oxo derivative and by removal of the N-protecting groups.
The preferred group of novel compounds obtained by this process are the 1-N- (ω-amino-α- hydroxyalkanoyl) -2'-hydroxy-2'- desamino-4,6-di-0- (aminoglycosyl)- 1,3-diaminocyclitols. The compounds obtained by the process of !this invention exhibit antibacterial activity
本发明涉及一种制备具有 6'-氨基功能的 2'-羟基-2'-二氨基-4,6-二-0-(氨基糖基)-1,3-二氨基环糖醇及其药学上可接受的酸加成盐的工艺,涉及通过该工艺获得的新型化合物和盐;还涉及包含这种新型化合物或盐的新型抗菌活性组合物。
该工艺包括在钨酸盐离子存在下,使相应的 N-保护(2'-氨基除外)-4,6-二-0-(氨基糖基)-1,3-二氨基环糖醇与过氧化氢反应,然后裂解由此形成的 2'-氧亚氨基衍生物,还原生成的 2'-氧代衍生物,并除去 N-保护基团。
通过该工艺获得的新型化合物的优选类别是 1-N-(ω-氨基-α-羟基烷酰基)-2'-羟基-2'-去氨基-4,6-二-0-(氨基糖基)-1,3-二氨基环糖醇。通过本发明工艺获得的化合物具有抗菌活性
