  • Publication number: 20040116385
    Abstract: Porphyrins containing one or more negatively-charged, amphiphilic nido-carborane substituents have antiviral or virucidal activity. The most active compounds tested to date are negatively charged, amphiphilic, and water-soluble. The negative charges lie primarily in the boron clusters. The carbon-carbon bonds linking the boron-containing groups to the porphyrin ring make the compounds highly resistant to hydrolysis. These compounds have strong potential for use as antiviral and virucidal drugs, as they are highly stable, water-soluble, negatively-charged, amphiphilic, and have low toxicity to normal mammalian cells. Preliminary tests in vitro have shown high activity against HIV.

  • Patent number: 5986074
    Abstract: The present invention relates to novel metal chelates, exemplified as technetium-99m or rhenium chelates, and to the process of preparing such metal chelates from corresponding ligands. These ligands and their corresponding metal chelates are synthesized to have a cysteinylethylene (EC) structure, a monothiourea (MTU) structure, or a dithiourea (DTU) structure. The present invention further relates to a pharmaceutical composition comprising a metal chelate, for example, a .sup.99m Tc-chelate, to the use of the composition for renal imaging and examination of renal function, and to a kit for preparing such a composition prior to use.

  • Patent number: 5281616
    Abstract: Compositions for the inhibition of replication of human immunodeficiency virus containing one or more "porphyrins" possessing antiviral activity. As used herein "porphyrins" includes porphyrins, phthalocyanines, chlorins, metallo derivatives thereof, and other porphyrin-like compounds. Examples of natural and synthetic, positively, negatively, and neutrally charged porphyrins, phthalocyanines, and derivatives thereof have been found to exhibit selective anti-HIV activity which is not dependent on the presence of light.

  • Patent number: 5192788
    Abstract: Compositions for the treatment or prevention of AIDS or other diseases resulting from infection with the Human Immunodeficiency Virus containing one or more porphyrins.Porphyrins are tetrapyrrole macrocyle compounds with bridges of one carbon joining the pyrroles. Porphyrins occur naturally and are made synthetically. Derivatives of porphyrins include porphyrins with one or more substituents on one or more of the rings, porphyrins in which the conjugation of the ring has been altered by addition of substituents, porphyrins in which one or more center nitrogens is attached to substituents such as metals, liganded metals, and organic moieties, metalloporphyrins and metalloporphyrin-ligand complexes.Examples of natural and synthetic, positively, negatively, and neutrally charged porphyrins and porphyrin derivatives have been found to exhibit selective anti-HIV activity which is not dependent on the presence of light.
