Abstract: Disclosed are compounds that release nitric oxide, e.g., a compound of Formula (I) wherein R1-10, X, and n are as described herein, which are NSAID derivatives comprising a diazeniumdiolate moiety N2O2?. The compounds are chemopreventive agents with gastric-sparing, analgesic, cardioprotective, and/or anti-inflammatory properties. Also disclosed is a pharmaceutical composition comprising a compound of the invention and a pharmaceutically acceptable carrier. Also disclosed is a method of preventing or treating cancer or treating inflammation or an inflammation-related condition in a mammal comprising administering an effective amount of a compound of the invention to the mammal.

Abstract: The invention described herein provides for novel nitric oxide-releasing polymers that comprise at least two adjacent units derived from acrylonitrile monomer units and containing at least one carbon-bound diazeniumdiolate. The diazeniumdiolated acrylonitrile-derived polymers can be used in medical devices therapeutically. Accordingly, the invention also provides a method of treating a biological disorder and a method of promoting angiogenesis that includes administering a medical device comprising a nitric oxide-releasing polymer comprising at least two adjacent units of acrylonitrile before exposure to nitric oxide and at least one nitric oxide releasing N2O2— group, wherein the N2O2— group is attached directly to the polyacrylonitrile backbone, to a specific location on or within the mammal in an amount effective to treat the biological disorder or promote angiogenesis.

Abstract: Mass-spectrometry based methods of analyzing estrogens and other steroids from biological samples are disclosed herein. Further disclosed are methods of detecting the presence of illegal steroids in a mammal. Methods of detecting a disease state or condition or elevated risk of a disease state or condition in a mammal are also disclosed. Also disclosed are kits for use in a method for detecting and/or quantifying one or more steroids in a sample by mass spectrometry.

Abstract: The present invention relates to nitric oxide-releasing amidine diazeniundiolates, compositions comprising same, methods of using same, and a method for preparing same from imidate diazeniumdiolates and primary or secondary amines.

Abstract: Diazeniumdiolates, wherein the N1 position is substituted by an inorganic or organic moiety and the O2-oxygen is bound to a substituted or unsubstituted aromatic group, are provided. Also provided are O2-glycosylated 1-substituted diazen-1-ium-1,2-diolates (O2-glycosylated diazeniumdiolates) and O2-substituted 1-[(2-carboxylato)pyrrolidin-1-yl]diazen-1-ium-1,2-diolates (1-[(2-carboxylato)pyrrolidin-1-yl]diazeniumdiolates). The O2-aryl diazeniumdiolates are stable with respect to the hydrolytic generation of nitric oxide in neutral to acidic solutions and generate nitric oxide in basic or nucleophilic environments or microenvironments. Also provided are compositions, including pharmaceutical compositions, comprising such compounds and methods of using such compounds.

Abstract: Methods for enhancing detection by mass spectroscopy (MS) and/or chromatographic separability of carbonyl-containing compounds such as steroids are disclosed. Reaction of a carbonyl compound with a sulfonhydrazide compound provides a sulfonhydrazone with enhanced ionization efficiency during the electrospray ionization process. In a particularly disclosed embodiment, derivatization of catechol estrogens with p-toluenesulfonhydrazide enhances both detection by atmospheric pressure ionization-MS (API-MS), such as electron spray ionization-MS (ESI-MS) and separation by liquid chromatography (such as HPLC) under reverse phase conditions. In yet other embodiments, the sulfonhydrazone is further reacted with a sulfonyl halide under alkaline conditions to derivatize hydroxyl groups in the compound. Prior formation of the sulfonhydrazide derivative protects the carbonyl bond of the compound during subsequent alkaline reaction with the sulfonyl halide.

Abstract: The present invention provides compound of the formula (I): in which at least two of R1, R2, R3, R4, R5, and R6 are N2O2M and related compounds, substrates, compositions, and methods of using such compounds and compositions to treat biological disorders in which a polyphasic release of nitric oxide would be beneficial.

Abstract: Extremely hydrophobic nitric oxide (NO) releasing polymers are disclosed. The extremely hydrophobic NO-releasing polymers provided are extensively cross-linked polyamine-derivatized divinylbenzene diazeniumdiolates. These polymers can be loaded with extremely high NO levels and designed to release NO in manners than mimic natural biological systems. The NO-releasing extremely hydrophobic polymers provided can maintain a sustained NO release for periods exceeding nine months. Also provided are related medical devices made using these NO-releasing extremely hydrophobic polymers.
