AMINOOLIGOSACCHARIDE "SK-4416", METHOD OF ITS SYNTHESIS, INHIBITOR OF SACCHARIDE HYDROLASE AND ANTIBACTERIAL AGENT Russian patent published in 1999 - IPC

FIELD: organic chemistry. SUBSTANCE: invention relates to a new aminooligosaccharide "SK-4416" of the formula (I) where n = 0 or 1; n = 1-4; m + n = 1-5; R₁ - lower alkylhydroxide and R₂ - hydrogen atom or lower alkyl and its pharmaceutically acceptable nontoxic salts that show strong capability to inhibit activity of saccharine hydrolase and antibacterial activity also. Invention relates to also a method of synthesis of this compound and pharmaceutical compositions containing on said as an active component. Authors isolated a new aminooligosaccharide derivative from the soil microorganism identified as Streptomyces species and found that it can be used as a strong inhibitor of saccharide hydrolase and antibacterial agents also. EFFECT: new compound indicated above, enhanced effectiveness of agent. 4 cl, 4 dwg, 6 tbl, 8 ex
