  • Publication number: 20040092490
    Abstract: This invention provides a method for treating or preventing malaria in a subject. The method includes administering to the subject an effective amount of a substituted tetracycline compound, such that malaria is treated or prevented. In one aspect, the invention relates to pharmaceutical compositions which include an effective amount of a tetracycline compound to treat malaria in a subject and a pharmaceutically acceptable carrier. The substituted tetracycline compounds of the invention can be used to in combination with one or more anti-malarial compounds or can be used to treat or prevent malaria which is resistant to one or more other anti-malarial compounds.

  • Publication number: 20040033996
    Abstract: The present invention relates to novel chemistries which allow for heretofore unobtainable substituted tetracycline compounds which exhibit significant antibacterial activity. The methods disclosed herein utilize reactive tetracycline-based precursor compounds, reactive organic substituent precursors and transition metal catalysts under conditions such that a tetracycline compound substituted with the desired organic substituent is formed. In one embodiment of the invention, a substituted tetracycline compound may be prepared by combining a reactive tetracycline-based precursor compound such as an arene tetracycline diazonium salt, and a reactive organic substituent precursor, e.g., alkenes, substituted alkenes, vinyl monomers, aromatics and heteroaromatics, in the presence of a transition metal catalyst, such as palladium chloride, under conditions such that a tetracycline compound substituted with the organic substituent is formed.
