摘要:Methods are provided for preventing neurodegeneration and neuronal loss by administering compositions comprising small molecule compounds with the effect of preventing neurodegeneration and neuronal loss. In one aspect of the invention, the methods and compositions are also useful for treating neurodegenerative diseases. Small molecule compounds provide an important treatment option because of their stability, ease of use in both manufacture and formulation, ease of administration, and patient compliance. The small molecule compound compositions of the present invention may include topoisomerase II inhibitors, bacterial transpeptidase inhibitors, calcium channel antagonists, cyclooxygenase inhibitors, folic acid synthesis inhibitors, or sodium channel blockers and functional analogues thereof that have an effect on neurodegeneration. The compositions of the present invention may be administered prophylactically before the onset of clinical symptoms or after clinical symptoms of a neurodegenerative disease have manifested.

摘要:The acetylmethyl ester of hetacyllin and/or its salts of an organic or inorganic acid are described and methods for their synthesis wherein a tertiary amine and chloroacetone are introduced to hetacyllin in an organic solvent or chloroacetone is introduced to hetacyllin in the form of a salt with an alkali metal in an organic solvent, and then from the reaction mixture, the acetylmethyl ester of hetacyllin is isolated in free form and, if desired, a salt of the ester is obtained by reaction with an organic or inorganic acid in an organic solvent. n As tertiary amines, trialkylamine, N-methylpiperidine, N-ethylpiperidine or N-methylmorpholine are used; as organic solvents in obtaining the ester, dimethylformamide, dimethylacetamide or dimethylsulfoxide are used. In obtaining salts of the ester the organic solvents used are aliphatic alcohols of a chain length C 2 -C 5 ; ketones, preferably acetone; ethers, such as diethyl, dipropyl, diisopropyl, dibutyl ethers, or their mixtures. n The obtained compounds show an antibacterial action like ampicillin but after administration per os they show a considerably higher level of the antibiotic than that after administration of free ampicillin or its esters.
