  • Patent number: 6689399
    Abstract: The present invention provides an anti-inflammatory composition for treatment of joint and muscle pain through transdermnal delivery of a capsacinoid in conjunction with glucosamine. The ingredients of the composition of the present invention, namely, a capsacinoid in combination with a primary amine, such as glucosamine, at a high concentration, interact in a synergistic manner to provide a prolonged effect of pain relief when used in the treatment of joint and/or muscle pain associated with an inflammatory response. The prolonged pain relief effect is achieved without incurring the intense burning or stinging sensation usually associated with topical capsaicin administration. The present invention also provides methods for relieving joint and/or muscle pain associated with an inflammatory response, which employ the composition of the present invention.

  • Patent number: 6214805
    Abstract: The present invention relates to methods of inhibiting infection by RNA viruses with complexes of an activator of RNase L and an oligonucleotide that is capable of binding to the genome, antigenome or mRNAs of a negative strand RNA virus to specifically cleave the genomic or antigenomic RNA strand of the virus. In accordance with the present invention, the methods and complexes of the invention may be applied to target any negative strand RNA virus. The invention in one embodiment relates to a covalently linked complex of an oligonucleotide that is capable of binding to the genomic or antigenomic template RNA strand of a negative strand RNA virus and/or binding to an mRNA of a viral protein (an “antisense oligonucleotide”) coupled to an activator of RNase L. In a preferred embodiment of the present invention, the oligonucleotide component of the complex is complementary to a region of the viral genomic RNA strand characterized by repeated or consensus sequences.
