Patent number: 6858649Abstract: The selective potentiation and/or inhibition of the 5-HT2A and/or 5-HT1A response to serotonin (5-HT) is achieved using analogs of oleamide. Selective potentiation and/or inhibition of the 5-HT2A and/or 5-HT1A leads to a modulation of serotonergic signal transduction of cells having various receptor subtypes. A subset of analogs is identified that inhibits rather than potentiates the 5-HT2A, but not the 5-HT1A, receptor response. These analogs enable the selective modulation of serotonin receptor subtypes and even have opposing effects on the different subtypes. An analysis of the activity of the oleamide analogs discloses that the structural features required for activity are highly selective. In particular, the presence, position, and stereochemistry of the 9-cis double bond is required and even subtle structural variations reduce or eliminate activity.Type: GrantFiled: April 30, 1998Date of Patent: February 22, 2005Assignee: The Scripps Research InstituteInventor: Dale L.

Patent number: 4908215Abstract: A one step process providing timed exposure to a substantially constant concentration of hypochlorite disinfectant is described, said process being completed when the hypochlorite is destroyed in an autocatalytic reaction with thiosulfate. The hypochlorite lifetime is precisely controlled by adjusting the initial pH of an alkaline disinfection solution of thiosulfate and hypochlorite, said solution containing a molar ratio of between 0.25 and 0.75 moles of thiosulfate to 1.00 mole of hypochlorite. Subsequently, with gradual evolution of acid and decreasing pH, the acid-dependent autocatalytic oxidation of thiosulfate is accelerated. This consumes the hypochlorite in a brief time interval, terminating the disinfection process. Also included in said alkaline disinfection solution is an appropriate concentration of Na.sub.2 HPO.sub.Type: GrantFiled: November 21, 1988Date of Patent: March 13, 1990Assignee: Brandeis UniversityInventor: Daniel Perlman
