  • Publication number: 20110146671
    Abstract: The present invention provides a pharmaceutical composition comprising a chemical compound or a herb extract or the combination having at least one of the activities of antiviral, antibacterial, antifungal, anti-inflammatory, anti-allergy, anti-cancer, promoting membrane healing or immunomodulating, for the treatment and prevention of a disease of a mammal. The present invention also provides a system for delivering the composition to the hard-to-reach sinuses of a mammal to reduce the load of the pathogen, to reduce the amount of inflammatory mediators, to heal pathological changes, and collectively to treat a disease of a mammal, such as allergic fungal rhinosinusitis. The invented method of treating a human disease reduces infectious and inflammatory agents without causing antibiotic resistance or adverse event.

  • Patent number: 6646005
    Abstract: Methods for treating hair loss using a composition including a compound having the following structure and pharmaceutically acceptable salts, hydrates, and biohydrolyzable amides, esters, and imides thereof are provided. R1 is —(CH2)n(CHNR7R8)mC(O)R9, wherein n is an integer from 1 to 3, and m is an integer from 0 to 1. R3 and R5each, independently, is chlorine, bromine, iodine and —CH3. R7 and R8 each, independently, is hydrogen or C1 to C4 alkyl. R9 is hydroxy, C1 to C4 alkoxy and —NR7R8. R31 is a hydrogen, chlorine, bromine, iodine, C1 to C4 alkyl, C4 to C6 cycloalklyl, C1 to C4 haloalkyl, C4 to C6 halocycloalkyl, or CH(R10)Ar. Ar is 5-hydroxypyrid-2-yl, 6-hydroxypyrid-3-yl, 6-hydroxypyridazin-3-yl, 6-methioxypyridazin-3-yl N-oxide or 6-hydroxypyridazin-3-yl N-oxide. R10 is hydrogen or C1 to C4 alkyl. R41 is hydroxy or C1 to C4 alkoxy.
