摘要:
The present invention relates to a cationic lipid having one or more biodegradable groups located in a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.
摘要:
The invention generally involves combining specialty amines with herbicidal carboxylic acids to form a new generation of salts with improved characteristics. The salts contain a cation of an amine and an anion of a carboxylic acid herbicide. The amine is advantageously selected from mono-isobutylamine (MIBA), N-methylaminoethanol (MMEA), dimethylaminopropylamine (DMAPA), 2-dimethylaminoethanol (DMAE), methyldiethanolamine (MDEA), and 1,2-diaminopropane (1,2-DAP). The amine-herbicide combinations may possess one or more improved characteristics, including maximum loading, wettability, drift, viscosity, and volatilization.
摘要:
The invention is a herbicidal composition containing an alkanolamine salt of an dicamba capable of remaining as a single phase liquid over a period of at least 1 week and containing low amounts of water and high loadings of the salt. Such herbicidal compositions are capable of remaining liquid in the absence of high amounts of water, thereby enhancing their capacity to remain liquid over an extended period of time when exposed to environmental conditions to improve their effectiveness to transport the active salt through a leafy substrate and can reduce transportation costs by increasing the salt loading without compromising the stability of the composition.
摘要:
The invention relates to a process for preparing primary amines, which comprises hydrogenating at least one nitrile in an apparatus (V1) in the presence of an unsupported cobalt catalyst to obtain at least one primary amine, with recurrent or continuous addition of at least one compound (I) to the apparatus (V1), said compound (I) comprising at least one component selected from alkali metal, alkaline earth metal and rare earth metal.
摘要:
The present invention describes a synergistic composition comprising of one or more statins, or one or more dipeptidyl peptidase IV (DPP IV) inhibitor or one or more biguanide antihyperglycaemic agent and a PPAR agonist of formula (1a) for the treatment of diabetes, especially non-insulin dependent diabetes or Type 2 diabetes and conditions associated with diabetes mellitus and to compositions suitable for use in such method. The invention also describes the preparation of such compositions. The present invention also relates to certain novel salts of the PPAR agonist of formula (I), processes for the preparation of: these novel salts and use thereof.

摘要:
A continuous method (P) for preparing diamine is described. The method includes reacting the corresponding alkene nitrile with the corresponding monoamine in order to form the corresponding aminonitrile. The monoamine can be introduced in molecular excess with respect to the alkene nitrile, wherein the unreacted monoamine is recirculated to the reaction; followed by reducing the aminonitrile produced by hydrogen in the presence of at least one alkali-metal hydroxide, water, and a hydrogenation catalyst; and purifying the diamine.
