    • The invention relates to a novel 2H-1-pyran-2-ones of general formula (I), wherein R1 represents an alkyl radical with 2-5 C atoms, a cycloakyl radical with 4-6 C atoms, a cycloalkyl radical with 4-8 C atoms or an alkoxy alkyl radical with a total of 3-5 C atoms and R2 represents a 2-(3, 4-methylene dioxyphenyl) radical or a 2-phenyl ethenyl radical substituted with R3, R4 and R5 in positions 3, 4 and 5, whereby independently from each other R3 and R5 represent methoxy or ethoxy and R4 is a straight chain or branched alkoxy radical with 1-5 C atoms, an alkenyl radical with 3-5 C atoms, a cycloalkoxy radical with 4-6 C atoms, a cycloalkyl radical with 4-8 C atoms or an alkoxy alkoxy radical with a total of 3-5 C atoms. The invention also relates to a method for producing said compunds in addition to novel untermediate products and to a method for the production thereof. The novel pyranone derivatives have an anti-convulsive and/or anti-epileptic efect in addition to a neuroprotective effect or act against neurodegenerate diseases. The invention further relates to medicaments containing these compounds.
    • 本发明涉及通式(I)的新颖的2H-1-吡喃-2-酮,其中R1表示具有2-5个C原子的烷基,具有4-6个C原子的环烷基,具有4个 -8个C原子或烷氧基烷基,R2表示2-(3,4-亚甲基二氧苯基)基或3-位置R3,R4和R5取代的2-苯基乙烯基, ,4和5,其中彼此独立地为R 3和R 5表示甲氧基或乙氧基,R 4为具有1-5个C原子的直链或支链烷氧基,具有3-5个C原子的链烯基, 6个C原子,具有4-8个C原子的环烷基或总共3-5个C原子的烷氧基烷氧基。 本发明还涉及一种除了新颖的非中间产物之外生产所述组合物的方法及其生产方法。 新型吡喃酮衍生物除了神经保护作用或抗神经变性疾病之外,还具有抗惊厥和/或抗癫痫效果。 本发明还涉及含有这些化合物的药物。
