Abstract: The invention refers to novel 2,3-benzodiazepine derivatives of formula (I) and pharmaceutical compositions containing the same as the active ingredient. The novel compounds antipasmodic, muscle relaxant and neuroprotective activities. In formula I; X represents a hydrogen atom, a chloro atom or a methoxy group; Y stands for a hydrogen atom or a halo atom; Z means a methyl group or a chloro atom; R is a C1-4 alkyl group or a group of the formula —NR1R2, wherein R1 and R2 represent, independently, a hydrogen atom, a C1-4 alkyl group, a C1-4 alkoxy group or a C3-6 cycloalkyl group.

Abstract: The invention relates to new 2,3-benzodiazepine derivatives of general Formula (I), (wherein R1 stands for methyl, formyl, carboxy, cyano, —CH?NOH, —CH?NNHCONH2 or —NR5R6, wherein R5 and R6 independently from each other represent hydrogen or lower alkyl or together with the nitrogen atom, they are attached to, form a 5- or 6-membered, saturated or unsaturated heterocyclic ring optionally containing one or more further nitrogen, sulfur and/or oxygen atom(s); R2 is nitro or amino; R3 stands for hydrogen, lower alkanoyl or CO—NR7R8, wherein R7 and R8 independently from each other stand for hydrogen, lower alkoxy, lower alkyl or lower cycloalkyl or together with the nitrogen atom, they are attached to, form a 5- or 6-membered, saturated or unsaturated heterocyclic ring optionally containing one or more further nitrogen, sulfur and/or oxygen atom(s); R4 is hydrogen or lower alkyl; the dotted lines have the following meaning: if R3 and R4 are not present, the bond between positions C8 and C9 is a single bond and th

Abstract: The invention relates to novel processes for the preparation of 5-chloro-4-{3-[N-[2-(3,4-dimethoxyphenyl)-ethyl]-N-methylamino]-propylamino-3(2H) pyridazinone of formula (I) and the pharmaceutically acceptable acid addition salts thereof. An important feature of the invention is using 3,4,5-trichloropyridazone as starting substance of the synthesis.

Abstract: A process is disclosed for the preparation of amorphous atorvastatin calcium which comprises dissolving crude atorvastatin calcium in a lower alkanol containing 2 to 4 carbon atoms or a mixture of such alkanols under heating and, after cooling, isolating the precipitated amorphous atorvastatin calcium.

Abstract: The invention relates to a process for the preparation of amorphous atorvastatin calcium by recrystallization of crude atorvastatin from an organic solvent which comprises dissolving crude amorphous atorvastatin calcium in a lower alkanol containing 2-4 carbon atoms or a mixture of such alkanols under heating and isolating the amorphous atorvastatin calcium precipitated after cooling. The atorvastatin calcium obtained is a known valuable agent useful in treating hyperlipidemia and hypercholestrolemia.

Abstract: The disclosure relates to a novel 8-substituted-9H-1,3-dioxolo-[4,5-h][2,3]benzodiazepine compound of formula I and pharmaceutically acceptable quaternary ammonium salts thereof, a process for preparing the same, a pharmaceutical composition containing a 8-substituted-9H-1,3-dioxolo-[4,5-h][2,3]benzodiazepine compound, and a method of treatment using the pharmaceutical composition. A complete description of the compound of formula I is found in the specification. The compounds of the general formula I possess unique competitive AMPA/kainite antagonist properties making them useful in the treatment of diseases where inhibition of the AMPA/kainite receptors may a favorable effect.
