Eflornithine is an agent that can be used to treat glioma, especially glioma of WHO Grade II or Grade III such as anaplastic glioma. Eflornithine can suppress or prevent mutations in glioma which can cause the glioma to progress to a higher grade. The present invention describes pharmaceutical compositions that contain eflornithine or a derivative, analog, or prodrug thereof. The pharmaceutical compositions can be prepared in a number of dosage forms and may contain another therapeutically active agent or an agent that enhances the therapeutic activity of the elformithine or the derivative, analog, or prodrug thereof. The present invention also describes a kit that includes dosage forms of pharmaceutical compositions according to the present invention.

Various embodiments of this invention are directed to pharmaceutical compositions and methods for treating disease. The compositions of such embodiments include reversible nitroxide derivatives of nitroalkenes. The methods of various embodiments include administering an effective amount of any of these pharmaceutical compositions to a patient in need of treatment.

Glycine is an organic compound that can be used in the making of a synthetic acid that obviates all the drawbacks of strong acids such as hydrochloric acid. The new compound is made by dissolving glycine in water, in a weight ratio of approximately 1:1 to 1:1.5. The solution is mixed until the glycine is essentially fully dissolved in the water. Once dissolution is complete, hydrogen chloride gas is dissolved in the solution to produce the new compound, which can be referred to as hydrogen glycine. Also disclosed is a method for adjusting the pH of a fluid, the method comprising adding an effective amount of a solution to the fluid for adjusting the pH thereof to a desired level, wherein the solution is prepared by mixing glycine in water to form a glycine solution; and adding hydrogen chloride to the glycine solution.

The disclosure relates polyoxometalate complexes and uses in the management, treatment, or prevention of cancer. In certain embodiments, the polyoxometalate complexes comprise polydentate oxygen bridging ligands such as those of the following formula: [POM{(OCH2)3CX}2], [M6O13{(OCH2)3CX}2], [V6O13{(OCH2)3CX}2], salts, or derivatives thereof wherein POM is a polyoxometalate, M is a metal, and X is defined herein. In certain embodiments, the disclosure relates to pharmaceutical compositions comprising polyoxometalate complexes disclosed herein.

The present invention is related to synthesis of highly pure cationic surfactant products by eliminating or reducing impurities generation that has beset prior art. This is achieved through the N-acylation of ester of amino acid and its inorganic salts or its organic salts (e.g. amino acid or hydrochloride of amino acid or sulfate of amino acid or acetate of amino acid etc.) in non-hydrolytic or nearly non-hydrolytic reaction conditions involving mono or biphasic reaction system with fatty acid halide (C.sub.4 to C.sub.20), under moderate uniform basic condition yielding high purity N-acyl substituted amino acid ester, particularly ethyl lauroyl arginate. The present process achieves pH control through process strategy rather than the measurement and control steps. This ambient temperature process is stable through a range of temperature variation eliminating rigid low temperature control.

The present invention provides a technology which enables introduction of an active ingredient (e.g. nucleic acids) into various cells with a high efficiency, and compounds used therefor. The present invention provides a compound represented by the formula: ##STR00001##
[wherein, each symbol is as defined in the present description] or a salt thereof.

The present invention relates to a process to prepare N,N-di(2-hydroxybenzyl) ethylenediamine-N,N-diacetic acid and salts thereof comprising a reaction between formaldehyde, ethylenediamine diacetic acid or a salt thereof and phenol at a pH of between 3 and 7 and a temperature below 60 C. wherein the reaction mixture contains 0.2 to 1.1 molar equivalents of alkali metalions on the molar amount of EDDA.
