Abstract:
The present invention provided an improved process for the preparation of Metformin compound of formula I or its pharmaceutically acceptable salts 5 thereof, by employing an alcoholic solvent throughout the process
Abstract:
The invention provides a combination of an antibacterial agent (in particular vancomycin or moenomycin) and a delivery agent, in which the delivery agent is bonded, or capable of binding, to the antibacterial agent, and in which the delivery agent is capable of binding to one or more structures on a bacterial cell membrane. The invention further provides the use of such combinations in treating or preventing bacterial infections.
Abstract:
La presente invención se refiere a un procedimiento de obtención de aminoácidos libres a partir de harinas de leguminosas, preferiblemente de garbanzos, que comprende las etapas de extracción, nanofiltrado, purificación mediante resinas de intercambio iónico y concentración del producto final.
