Chemical syntheses and medical uses of novel inhibitors of the gastric H⁺, K⁺-ATPase for the treatment and/or management of duodenal ulcers, heartburn, acid reflux, other conditions mediated by gastric acid secretion and/or psoriasis are described.

RNA interference is provided for inhibition of ocular hypertension target mRNA expression for lowering elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension. Ocular hypertension targets include carbonic anhydrase II, IV, and XII; β1- and β2 adrenergic receptors; acetylcholinesterase; Na⁺/K⁺-ATPase; and Na—K-2Cl cotransporter. Ocular hypertension is treated by administering interfering RNAs of the present invention.

An enteric coated pharmaceutical extended release dosage form of a H+, K+-ATPase inhibitor giving an extended plasma concentration profile of a H+, K+-ATPase inhibitor. The extended plasma profile is obtained by a pharmaceutical composition which comprises a core material of a hydrophilic or hydrophobic matrix, and the H+, K+-ATPase inhibitor and optionally pharmaceutically acceptable excipients. The dosage form may be administered once daily.

Methods and kits for detecting the presence of ATP, for measuring ATP concentrations, and for detecting viable cells using a composition comprising an ATP-dependent enzyme and one or more ATPase inhibitors.

A method of treating gastric acid disorders by administering to a patient a pharmaceutical composition comprising a proton pump inhibitor (PPI) in a pharmaceutically acceptable carrier.

The present invention provides an oral solution/suspension comprising a proton pump inhibitor and at least one buffering agent. The PPI can be any substituted benzimidazole compound having H⁺,K⁺-ATPase inhibiting activity and being unstable to acid. Omeprazole and lansoprazole are the preferred PPIs for use in oral suspensions in concentrations of at least greater than 1.2 mg/ml and 0.3 mg, respectively. The liquid oral compositions can be further comprised of parietal cell activators, anti-foaming agents and/or flavoring agents. The inventive compositions can alternatively be formulated as a powder, tablet, suspension tablet, chewable tablet, capsule, effervescent powder, effervescent tablet, pellets and granules. Such dosage forms are advantageously devoid of any enteric coating or delayed or sustained-release delivery mechanisms, and comprise a PPI and at least one buffering agent to protect the PPI against acid degradation. Similar to the liquid dosage form, the dry forms can further include anti-foaming agents, parietal cell activators and flavoring agents. Kits utilizing the inventive dry dosage forms are also disclosed herein to provide for the easy preparation of a liquid composition from the dry forms. In accordance with the present invention, there is further provided a method of treating gastric acid disorders by administering to a patient a pharmaceutical composition comprising a proton pump inhibitor in a pharmaceutically acceptable carrier and at least one buffering agent wherein the administering step comprises providing a patient with a single dose of the composition without requiring further administering of the buffering agent. Additionally, the present invention relates to a method for enhancing the pharmacological activity of an intravenously administered proton pump inhibitor in which at least one parietal cell activator is orally administered to the patient before, during or after the intravenous administration of the proton pump inhibitor.

The present invention is directed to preventing the consequences of the misfolding of proteins, such as those associated with protein folding diseases. Provided are methods of treatment that involve administering an agent that decreases the level of the heat shock protein ATPase Aha1 and/or related molecules with similar function. Such methods can result in the rescue of folding, trafficking, and function of proteins with suboptimal folding kinetics. Also provided are screening methods to identify agents for the treatment of protein misfolding disease

The present invention is related to novel oral compositions comprising an irreversible gastric H⁺/K⁺-ATPase proton pump inhibitor (PPI) as a gastric acid secretion inhibitor, pentagastrin (PG) or a PG analogue as an activator of parietal cells in the gastric lumen. In a preferred embodiment, the composition further comprises at least one agent that preserves the availability of PG in the gastric fluids, thus enabling PG to act locally in the stomach. Unexpectedly, the compositions of the present invention exhibit anti-acid activity locally in the stomach that is meal-independent, exhibit fast onset and prolonged inhibition of acid secretion.

The present invention provides methods of producing libraries of compounds with enhanced desirable properties and diminished side effects as well as the compounds produced by the methods. In preferred embodiments, methods of the present invention use a universal chemical glycosylation method that employs reducing sugars and requires no protection or activation. In a preferred embodiment, the invention provides a library of neoglycoside digitoxin analogs that includes compounds with significantly enhanced cytotoxic potency toward human cancer cells and tumor-specificity, but are less potent Na⁺/K⁺-ATPase inhibitors in a human cell line than digitoxin.

The reagent, pharmaceutical formulation, kit, and methods of the invention provides a new approach to treat refractory cancers using Na⁺/K⁺-ATPase inhibitors, such as cardiac glycosides, including bufadienolides or their corresponding aglycones (e.g., proscillaridin, scillaren, and scillarenin, etc.), especially in oral formulations and/or solid dosage forms containing more than 1 mg of active ingredients.

Novel polypeptides for one such target, DNA-dependent ATPase A, and novel polynucleotides encoding DNA-dependent ATPase A are disclosed. Phosphoaminoglycoside compounds which act on such protein targets to inhibit nucleic acid metabolism. In addition, screening assays for identifying compounds that inhibit nucleic acid-dependent ATPase activity, including, but not limited to, DNA-dependent ATPase A, are disclosed. Such compounds are useful in the treatment of diseases, including but not limited to cancer and infectious disease, through disruption of nucleic acid metabolism and induction of apoptosis. Moreover, methods for prevention and treatment of diseases including, but not limited to cancer and infectious disease are disclosed.

A method for the preparation of homogeneous microparticles containing a H⁺,K⁺-ATPase inhibitor by a spray freezing technique characterized in that the medium to be atomized into droplets is having a high solid content and comprising besides the acid labile H⁺,K⁺-ATPase inhibitor also a polymer and a liquid in which the polymer is soluble.
