Patent number: 10271556Abstract: The present invention is a surfactant(s) for use as a cleaner and freshener as well as methods for the production/use of such surfactants/cleaners/fresheners. The surfactant is produced using and relying upon properties of the Liquidambar tree, particularly the Liquidambar leaf, by creating a liquid solution useful for cleaning and freshening purposes by soaking or steeping the leaves of Liquidambar in a solvent, preferably water. The solutions formed have been found to be effective for general cleaning and freshening purposes including, but not limited to, all known household cleaning/freshening purposes as well as for personal bodily cleaning/freshening purposes including, but not limited to, body washing, hair washing, tooth brushing, mouth washing, and the like. It is non-allergenic, non-toxic, and will cause no adverse environmental effects.Type: GrantFiled: May 21, 2014Date of Patent: April 30, 2019Inventor: G. Richard Knox, Jr.

Publication number: 20070166296Abstract: A compound comprising a target cell-specific portion and human NAD(P)H:quinone reductase 2 (NQO2) or a variant or fragment or fusion or derivative thereof which has substantially the same activity as NQO2 towards a given prodrug, or a polynucleotide encoding said NQO2 or said variant or fragment or fusion or derivative. A recombinant polynucleotide comprising a target cell-specific promoter operably linked to a polynucleotide encoding human NAD(P)H:quinone reductase 2 (NQO2) or a variant or fragment or fusion or derivative thereof which has substantially the same activity as NQO2 towards a given prodrug. The compounds and polynucleotides are useful in a method of treating a patient in conjunction with a suitable prodrug.Type: ApplicationFiled: November 9, 2006Publication date: July 19, 2007Inventors: Philip Burke, Richard Knox

Publication number: 20060291020Abstract: Systems and methods for providing illumination suitable for imaging devices such as laser projection systems, wherein the illumination pattern is adjustable by modifying one or more characteristics of a controlled angle diffuser. In one embodiment, a highly collimated (e.g., laser light) beam is passed through a holographic diffuser to create a well defined cone angle for the light emanating from each point on the diffuser. This light is focused into an illumination image that is controlled by the prescription of the diffuser. In one embodiment, the diffuser can be positioned to alternately place different regions having different prescriptions in the optical path corresponding to the illumination image. In one embodiment, the diffuser can be continually moved to eliminate speckling and “worminess” in the illumination image.Type: ApplicationFiled: March 7, 2005Publication date: December 28, 2006Inventors: Richard Knox, Kevin Hathaway, David Kappel, Robert Fischer, Biljana Tadic-Galeb

Publication number: 20060106005Abstract: The invention provides metallocene compounds of formula 1 for use as medicaments in the treatment of cancer. wherein R1, R2, R3 and R4 represent a combination of H, alkyl, aryl or trimethylsilyl; L represents side chain substituents, at least one of which contains a group which enables the compound to become water-solubilised; X is halo, alkoxy, acetate or H2O; Y is a counter-ion; M is a metal; and n=1 or 2. The invention also provides novel compounds of the formula 1 wherein at least one of the groups L comprises a quaternary tetraalkylammonium group. The compounds have been shown to have significantly greater activity in the treatment of cancer than the compounds known from the prior art.Type: ApplicationFiled: July 4, 2003Publication date: May 18, 2006Inventors: Patrick McGowan, Richard Knox

Patent number: 5958682Abstract: A system is disclosed which comprises: (i) a viral vector comprising a nucleotide sequence encoding a nitroreductase, which nitroreductase is capable of converting a prodrug into a cytotoxic drug; and (ii) a prodrug capable of being converted into a cytotoxic drug by the nitroreductase encoded by the vector. The disclosed invention also includes methods for killing cancerous and/or non-cancerous cells using the system described above. Included in the invention are methods for killing cells in vitro by introducing a vector encoding a nitroreductase into the cells, and then by providing a prodrug to the cells growing in vitro. Also included are methods in which cancerous and/or non-cancerous cells are killed in vivo in an animal or human by administering the vector and prodrug directly to cells of the animal or human.Type: GrantFiled: July 1, 1996Date of Patent: September 28, 1999Assignee: Cancer Research Campaign Technology LimitedInventors: Thomas Connors, Richard Knox, Roger Sherwood

Patent number: 5633158Abstract: The invention provides a nitroreductase, obtainable from a bacterium having the following characteristics as exemplified by examples isolated from Escherichia coli B and Bacillus amyloliquifaciens: 1) it is flavoprotein having a molecular weight in the range of 20-60 Kilodaltons; 2) it requires either NADH or NAD(P)H or analogues thereof as a cofactor; 3) it has a Km for NADH or NAD(P)H in the range of 1-100 .mu.M; and 4) it is capable of reducing either or both nitro groups of CB1954 and analogues thereof to a cytotoxic form e.g. the hydroxylamine. The sequence of one such nitroreductase is shown in Seq. ID No. 1. The nitroreductase may be conjugated to a tumor targeting agent such as a monoclonal antibody and used to convert prodrugs into active antitumor agents. Such prodrugs and drugs are also provided.Type: GrantFiled: July 27, 1994Date of Patent: May 27, 1997Assignee: Cancer Research Campaign Technology LimitedInventors: Gillian Anlezark, Roger Melton, Roger Sherwood, Thomas Connors, Frank Friedlos, Michael Jarman, Richard Knox, Anthony Mauger
