Abstract:
The present invention provides novel phenazine derivatives, such as compounds of Formula (I) and (II), and pharmaceutically acceptable salts thereof. The compounds of the invention are expected to be anitmicrobial agents and may act by a microbial warfare strategy (e.g., a reactive oxygen species (ROS)-based competition strategy). The present invention also provides pharmaceutical compositions, kits, uses, and methods that involve the compounds of the invention and may be useful in preventing or treating a microbial infection (e.g., a bacterial infection) in a subject, inhibiting the growth and/or reproduction of a microorganism (e.g., a bacterium), killing a microorganism (e.g., a bacterium), inhibiting the formation and/or growth of a biofilm, or reducing or clearing a biofilm.
Abstract:
This invention pertains generally to processes, uses, methods and materials utilising xanthylium compounds of formula (II) as further defined herein. These compounds are useful as drugs, for example, in the treatment of tauopathies, such as Alzheimer's disease.
Abstract:
A process of making a polymeric phenazonium compound having the general formula: wherein R 1 , R 2 , R 4 , R 5 , R 6 , R 8 and R 9 are the same or different, and represent hydrogen, a low alkyl or a substituted aryl, R 3 stalls as NH 2 and is diazotized followed by polymerization, R 5 and R 8 may alternatively represent monomeric or polymeric phenazonium radicals, R 7 is a carbon in the aromatic ring, and wherein R X -N-R Y represents a substituted amine, and R x and R y represent any combination of CH 3 , C 2 H 5 , and hydrogen, except that R x and R Y cannot both be hydrogen, A is an acid radical, and n is an integer from 2 to 100. The polymeric phenazonium compound is usable in as an additive in a metal plating bath. The method includes the steps of: a) dissolving an effective amount of an amino compound in a formic acid solution; b) adding a nitrite salt to diazotize the amino compound; and c) adding sulfamic acid to neutralize any excess nitrous acid that may be fonned in step b), whereby a polymeric phenazonium compound is produced.
Abstract:
The present invention provides a family of dark quenchers, termed Black Hole Quenchers ("BHQs"), that are efficient quenchers of excited state energy but which are themselves substantially non-fluorescent. Also provided are methods of using the BHQs, probes incorporating the BHQs and methods of using the probes.
Abstract:

Abstract:
The invention is directed to novel sEH inhibitors and their use in the treatment of diseases mediated by the sEH enzyme. Specifically, the invention is directed to compounds according to Formula I: wherein R1, R2, R4, R5, R6, A, B, Y, Z, n, and m are defined below, and to pharmaceutically-acceptable salts thereof. The compounds of the invention are sEH inhibitors and can be used in the treatment of diseases mediated by the sEH enzyme, such as hypertension. Accordingly, the invention is further directed to pharmaceutical compositions comprising a compound of the invention. The invention is still further directed to methods of inhibiting sEH and treatment of conditions associated therewith using a compound of the invention or a pharmaceutical composition comprising a compound of the invention.
Abstract:
