Conjugates derived from non-steroidal anti-inflammatory drugs (NSAIDs) and methods of use thereof are disclosed, useful for, inter alia, identifying and localizing the site of pathology and/or inflammation responsible for the sensation of pain in a patient; for identifying the sites of primary, secondary, benign, or malignant tumors; and for diagnosing infection or confirming or ruling out suspected infection. The NSAID-based conjugates contain an imaging moiety. The conjugates concentrate at sites of increased cyclooxygenase expression, thus revealing the sites of increased prostaglandin production, which is correlated with pain and inflammation, and correlated with tumor presence and/or location. Identifying areas of increased COX expressing can also aid in screening for infections.

[EN] This invention provides a process for forming secondary diamines. The process comprises bringing together a) at least one aliphatic hydrocarbyl ketone or aldehyde in which the carbon atom(s) alpha to the carbonyl group are primary or secondary and the hydrocarbyl portion of the ketone or aldehyde is linear or branched; b) at least one aliphatic primary diamine which is an aliphatic primary a,?-diamine, c) hydrogen; and d) a hydrogenation catalyst selected from platinum on carbon, palladium on carbon, sulfided platinum on carbon, sulfided palladium on carbon, and a mixture of any two of the foregoing. The process is conducted at a temperature in the range of about 20 °C to about 76 °C and at a hydrogen pressure in the range of about 1 to about 85 pounds per square inch gauge, such that a secondary diamine is formed. [FR] L'invention concerne un procédé de formation de diamines secondaires. Le procédé comprend le rassemblement a) d'au moins une hydrocarbyl cétone ou un hydrocarbyl aldéhyde aliphatique dans lequel le ou les atomes de carbone alpha par rapport au groupe carbonyle sont primaires ou secondaires et la portion hydrocarbyle de la cétone ou de l'aldéhyde est linéaire ou ramifiée ; b) d'au moins une diamine primaire aliphatique qui est une a,?-diamine primaire aliphatique, c) de l'hydrogène ; et d) d'un catalyseur d'hydrogénation choisi parmi platine sur carbone, palladium sur carbone, platine sulfuré sur carbone, palladium sulfuré sur carbone et un mélange de deux quelconque d'entre eux. Le procédé est conduit à une température se situant dans une plage d'environ 20 °C à environ 76 °C et à une pression d'hydrogène se situant dans une plage d'environ 1 à environ 85 livres par pouce carré relative, de sorte qu'une diamine secondaire est formée.
Structure−Activity Relationships of Acetylcholinesterase Noncovalent Inhibitors Based on a Polyamine Backbone. 2. Role of the Substituents on the Phenyl Ring and Nitrogen Atoms of Caproctamine
therapeutics, we investigated the structure-activity relationships (SAR) of a lead compound (caproctamine, 3) identified in a previous work. In particular, we varied the substituents on the phenyl ring and on the nitrogen functions (both the amine and the amide), and studied the effects of such modifications on the inhibitory potency against isolated acetyl- and butyryl-cholinesterase (AChE and BChE). Moreover
