Abstract: The invention relates to cyclic bioisosteres of derivatives of a purine system having a general structural formula R1=—H, —NH2, —Br, —Cl, —OH, —COOH, B=—N?, —CH?, Z=—CH?, —N?, A=—N? at B=—N?, Z=—CH—, A=—CH? at B=—N?, Z=—CH—, A=—CH? at B=—N?, Z=—N?, A=—CH? at B=—CH?, Z=—CH?, A=—CH? at B=—CH?, Z=—N?, and their pharmacologically acceptable salts having a normalizing effect on endocellular processes, in particular, it is capable eliminating endocellular metabolic acidosis and capable of binding excessively formed free radicals, in particular, free-radical forms of oxygen, capable of normalizing the nitrergic mechanisms of the cells, and also capable of interreacting with adenosine-sensitive receptors on the membrane of non-nuclear cells and in nuclei-containing cells to decrease the aggregation of thrombocytes. The compounds according to the invention have hepatoprotective effect and can be used for producing pharmaceutical compositions on their base.

Abstract: A method for microstructuring by means of locally selective sublimation is disclosed, whereby patterns or images of organic electroluminescent components are produced by application of low molecular weight emission material, provided on a support, to those points of substrate corresponding to the pattern or image for production, by means of sublimation. According to the invention, the method is carried out by firstly completely coating a film support made from temperature-resistant material with the emission material. The coated support and the substrate are then placed adjacent and parallel to each other in a vacuum chamber. The side of the support coated with the emission material faces the substrate. The support is subsequently locally heated for a short period of time on the non-coated side thereof in those positions corresponding to the pattern or image for generation, to a temperature adequate for the sublimation of the emission material.

Abstract: A two-layered anode (1?) has a lower layer (2) including a non-conductive carrier material to which a conductive electrode layer (3?) is applied. Non-conductive areas, formed by partial removal of the electrode layer, have a predetermined structure corresponding to the structure of a structured polymer film (11) to be formed. The anode (1?) is connected with a platinum cathode in an electrolyte into which compounds of low molecular weight, preferably monomers of the polymer film (11), are introduced. During current flow, a conductive polymer film (11) of the predetermined structure is formed on conductive areas brought into contact with the electrolyte. A non-conductive substrate layer (13) is applied to the structured polymer film (11). The structured polymer film (11) adheres to the non-conductive substrate layer (13) and can be released from the electrode (1?) without damaging the electrode.

Abstract: A two-layered anode (1′) is used for the electrochemical polymerisation. The lower layer (2) consists of a non-conductive carrier material to which a conductive electrode layer (3′) is applied, the electrode layer being removed in part-areas in order to form non-conductive areas. the non-conductive areas have a predetermined structure which corresponds to the structure of the structured polymer film (11) to be formed. the anode (1′) is held together with a platinum cathode in an electrolyte into which compounds of low molecular weight, preferably monomers of the polymer film (11) to be formed, are introduced. A current flow is produced through the electrolyte via the anode (1′) and cathode. In the course of this a conductive polymer film (11) of the predetermined structure is formed on the conductive areas which are brought into contact with the electrolyte.
