Patent number: 7211603Abstract: The invention provides novel tetradentate enediyne ligands that are themselves thermally stable, yet react at about room temperature or slightly higher upon addition of metal ions or under photothermal conditions. In another aspect of the invention, a method of treating a disorder in a mammal comprising administering a therapeutically effective amount of a compound or composition is provided. In addition, the free ligand can be delivered to the mammal prior to complexation to metals, such that the ligand is exposed to a metal in the body and forms a metal complex in vivo. Furthermore, a metal complex of the invention can be administered to the mammal such that the complex exchanges the first metal center with another endogenous metal in order to form a second metal complex in vivo. The second metal complex is capable of forming a benzenoid diradical under physiological conditions and/or under photothermal conditions.Type: GrantFiled: September 29, 2005Date of Patent: May 1, 2007Assignee: Indiana University Research and Technology CorporationInventors: Jeffrey M. Zaleski, Diwan Singh Rawat

Patent number: 6677491Abstract: The present invention relates to a fragrance delivery system for use in laundry detergent compositions including rinse-added and dryer-added fabric conditioning compositions which provides a long lasting “freshness” or “clean” scent to fabric. The compositions described herein deliver highly fabric substantive linear acetal and/or ketal pro-fragrances to the fabric surface during laundering wherein the pro-fragrances release their fragrance raw materials over a period of up to two weeks. The present invention also relates a method for delivering a pleasurable scent to fabric which has a lasting freshness quality by contacting the fabric with a laundry detergent composition which comprises the fragrance-releasable pro-fragrances.Type: GrantFiled: May 9, 2002Date of Patent: January 13, 2004Assignee: Procter & Gamble CompanyInventor: Mark Robert Sivik
