  • Patent number: 7956086
    Abstract: A method for the manufacture of a sterile intravenous or intramuscular formulation of artesunic acid and the formulation are the subject of this invention. First the artesunic acid powder is sterilized with ethylene oxide and placed into a sterile container. The contained sterilized powder is then dissolved in sterile sodium phosphate buffered solution to produce an injectable intravenous or intramuscular formulation. The sodium phosphate dissolves and dilutes the artesunic acid powder without caking or frothing resulting in an improved drug product. The invention also relates to the formulation and a method of treating a patient with either uncomplicated or severe and complicated malaria.
    Type: Grant

  • Publication number: 20020115678
    Abstract: This invention relates to the treatment of antibiotic-resistant infections, including particularly infections caused by bacteria, Mycobacteria and fungi. A preferred group of compositions of the invention contain as active agents compounds containing pyridyl, quinolyl or benzoquinolyl ring systems substituted on the nitrogen-containing ring at the carbon opposite the nitrogen by a carbon bound to an oxygen which is also bound to a nitrogen through a saturated carbon or carbon chain, or, in the case of the pyridyl ring system, the substituent at the 4 position of the pyridyl ring may be an alkyl which may be substituted with halo, hydroxy, alkoxy, amino or alkylamino.

  • Patent number: 6268383
    Abstract: This invention relates to compounds of the general formula: wherein A is a aromatic hydrocarbon ring system and R1 is a carbon bound directly to an oxygen and is also bound to a nitrogen through a saturated carbon and wherein at least one of R2, R3 and R4 is an electron-rich substituent. The active agents are useful for treating patients suffering from infections including gram positive organisms, such as streptococcus, staphylococcus, anthracis, gram negative bacteria such as neisseria species, yeasts and mycobacterium. They are effective against strains which have shown resistance to other antimicrobial agents.
