Patent number: 10377701Abstract: A method of manufacturing 2-(1-{6-[(2-[F-18]fluoroethyl)(methyl)amino]-2-naphthyl}ethylidene)-malononitrile ([F-18]FDDNP) utilizes a semi-automated module that is used to perform fluorination, pre-purification, separation, product extraction, and formulation. The method is able to produce [F-18]FDDNP with high yields and ready for human administration under existing FDA regulations, and without the need for hazardous organic solvents such as dichloromethane (DCM), methanol (MeOH), and tetrahydrofuran (THF). The method also improves the speed with which [F-18]FDDNP can be synthesized with the method being able to generate a final product within about 90 to 100 minutes. This synthesis method is easily adaptable to FDA registered and approved automated synthesis systems.Type: GrantFiled: November 8, 2017Date of Patent: August 13, 2019Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Nagichettiar Satyamurthy, Jie Liu, Jorge R.

Patent number: 7094918Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well.Type: GrantFiled: April 28, 2003Date of Patent: August 22, 2006Assignee: Milliken & CompanyInventors: Jusong Xia, Mary E. Mason, Eric B. Stephens
