专利号:US-4902790-A 优先权日:1985-10-10 标 题 :Novel process for the synthesis of amikacin 发明人:MANGIA ALBERTO; GIOBBIO VICENZO; ORNATO GIORGIO 权利人:PIERREL SPA 摘要:A novel process for the synthesis of amikacin starting from kanamycin A protected at the positions 3 and 6' is described comprising the reaction of kanamycin A with a salt of a bivalent metal cation selected from zinc, nickel, iron, cobalt, manganese, copper and cadmium in the presence of water as the solvent or co-solvent followed by the in situ reaction of the resulting complex with a reactive derivative of L-amino-2-hydroxy-butyric acid, removal of the metal cation of the protecting groups and purification of the thus obtained raw product. The acylation under these conditions is extremely selective.

The invention includes administering an effective amount of a carbapenem compound or salt and/or prodrug thereof to a host in need of such a treatment. The present invention is also in the field of synthetic organic chemistry and is specifically provides an improved method of synthesis of β-methyl carbapenems which are useful as antibacterial agents.
专利号:US-6015808-A 优先权日:1993-08-20 标 题 :Synthesis of pharmaceutical compositions with lactams and β-lactams/oxo thia azabicyclo compounds 发明人:THIRUMALACHAR MANDAYAM JEERSAN; NARASIMHAN JR MANDAYAM JEERSAN 摘要:Pharmaceutical compositions with heretofore unknown and enhanced physical, chemical, and biological properties are prepared by combining known biologically active parent compounds with oxo thia azabicyclo compounds, such as lactam and beta -lactam compounds, capable of rapidly transporting the parent compounds in undegraded form to their target sites of action. A process for combining the parent compound with beta -lactam compounds consists of dissolving the parent compound in a polar solvent, adding a beta -lactam compound, incubating the resulting mixture, followed by drying, and subjecting the remaining solid material to solvent washing or extraction to further purify the new pharmaceutical composition. The new pharmaceutical composition possesses the biological and therapeutic activity of the parent compound and the barrier penetrating characteristics of the beta -lactam compound, which results in improved pharmacodynamics, including bioavailability, and an improved chemotherapeutic index, such that lower amounts of the parent may be used to avoid the toxic effects of the parent compound. Some of the new pharmaceutical compounds provide for the first time parent compounds in an orally administerable form.
