摘要:
The invention relates to N-hydroxysulfonamide derivatives that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. Novel N-hydroxysulfonamide derivatives release HNO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of functional groups on the N-hydroxysulfonamide derivatives.

摘要:
Disclosed herein is a polyhydroxy ketal adduct obtained by the esterification of a hydrocarbon polyol by at least 1.5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. The intermediate polyketocarboxylic ester is then ketalized to produce the polyhydroxyketal adduct, which can be used to provide a polymeric composition.
摘要:
A lithium secondary battery comprises an anode capable of intercalating or disintercalating lithium ions, a cathode configured with a lithium-containing oxide, and a nonaqueous electrolyte solution. The lithium-containing oxide comprises a lithium nickel based oxide. The nonaqueous electrolyte solution comprises vinyl ethylene carbonate (VEC) and a mono-nitrile compound. This lithium secondary battery solves the deterioration of charge/discharge cycle characteristics caused by a lithium nickel based oxide used for a cathode, and also controls the decomposition reaction of electrolyte to solve the swelling phenomenon even though the battery is stored at a high temperature or charged/discharged in a fully-charged state, thereby improving high-temperature life characteristics.

The present invention provides therapeutically active compounds and compositions as NMDA and MC receptor antagonists, which are useful in preventing and treating central nervous system disorders by inhibiting over-activation of NMDA and/or MC receptors. In one aspect, the present invention provides methods of treating and/or preventing neurodegenerative diseases and neuropathological disorders, methods of providing neuroprotection under stress conditions such as a stroke, methods of enhancing the brain's cognitive functions and methods of treating depression, anxiety and cachexia induced by a chronic disease in mammals and humans.
