US Classification:

514394, 5483047, 549472

Abstract:

Asymmetric derivatives of furamidines with one of the phenyl rings of furamidine replaced with a benzimidazole have been found by quantitative footprinting analyses to bind GC containing sites on DNA more strongly than to pure AT sequences. These compounds have been shown to bind in the minor groove at specific GC containing sequences of DNA in a highly cooperative manner as a stacked dimer. Compounds of the present invention find use in selectively binding mixed sequence DNA, and may also be used in methods of regulating gene expression, methods of treating opportunistic infections and cancer, as well as in methods of detecting certain sequences of DNA.

Abstract:

Pentamidine and analogs thereof have activity as imidazoline receptor binding compounds. A method of binding the imidazoline receptor, comprises contacting a bis-benzene to said imidazoline receptor in an amount effective to bind to said receptor, wherein said bis-benzene contains at least one amidine group (e. g. , one or two). The contacting step may be carried out in vivo or in vitro. Contacting may be carried out with individual active compounds or with libraries of active compounds.

Abstract:

In one aspect, the invention relates to a method of treating infectious bursal disease (IBD) in an avian subject in need of such treatment. The method comprises administering to the subject a compound of the formulas (I) through (IV) or a pharmaceutically acceptable salt thereof in an amount sufficient to treat IBD. In another aspect, the invention relates to a method of producing active immunity against infectious bursal virus disease (IBD) in an avian subject. The method comprises administering to a subject an immunogenic-amount of an IBDV vaccine and a compound selected from the compounds of formulas (I) through (IV) described herein. The compound represented by formulas (I) through (IV) is administered in an amount sufficient to induce an immune response in the avian subject.
