Abstract:
Disclosed are salts of nucleoside analogs and methods of forming the salts. An anion of a nucleoside analog is paired with a permanent counter cation to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. Also a cation of a nucleoside analog is paired with a permanent counter anion to form a salt that has decreased melting point and increased aqueous solubility compared to the nucleoside compound prior to the salt formation. The nucleoside analog in some embodiments has therapeutic activity such as antiviral. The permanent counter cation or anion in some embodiments has bioactivity such as antibacterial or being a vitamin.

Abstract:
New stabilizers for solutions of choline hydroxide and related quaternary trialkylalkanolamines are disclosed. The stabilizers are alkyl hydroxylamines, hydrazines, hydrazides, or derivates thereof, including compounds containing more than one such functionality. The new stabilizers are effective at concentrations less than about 1000 ppm, and choline hydroxide solutions stabilized with the compounds described herein typically have Gardner Color change less than about 2.0 after six months at reasonable temperatures.
Abstract:
A method of removing a residue from a surface, including applying to the surface a composition including (a) a quaternary ammonium hydroxide having a general formula (I): as defined herein, and (b) a dipolar aprotic solvent substantially free of water; and removing at least a substantial portion of the residue from the surface.
Abstract:
6-chloro-3-[2-(1-ethyl-propylamino)-3,4-dioxo-cyclobut-1-enylamino]-2-hydroxy-N- methoxy-N-methyl-benzenesulfonamide choline, solid pharmaceutical compositions and oral dosage forms that contain said compound, and a method of using such compositions and oral dosage forms to treat people who have inflammatory, obstructive or allergic conditions and diseases.
Abstract:
The present invention refers to joint mixtures of phenylbutyric acid or its ions and at least one organic molecule, like organic salts of phenylbutyrate, polymorphs, hydrates or solvates thereof and co-crystals of phenylbutyric acid and at least one organic molecule, polymorphs, hydrates or solvates thereof, as well as their use in cancer therapy and other pharmaceutical applications.
Abstract:
Novel radiotracer(s) for Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) imaging of disease states related to altered choline metabolism (e.g., tumor imaging of prostate, breast, brain, esophageal, ovarian, endometrial, lung and prostate cancer - primary tumor, nodal disease or metastases). The present invention also describes intermediate(s), pre-cursor(s), pharmaceutical composition(s), methods of making, and methods of use of the novel radiotracer(s).
