标题:Apparatus and method used in multiple, simultaneous synthesis of general compounds

摘要:The apparatus and method of the present invention provides for conducting simultaneous multiple synthesis of general compounds, which often takes place under varied uneven conditions requiring heating, cooling, agitation, reagent/solvent additions to the reactor contents at each reaction vessel location, supply and maintenance of inert atmosphere and means to facilitate the reflux of the reactor contents. Thus, it becomes necessary to monitor and control the reaction conditions during the simultaneous multiple synthesis of general compounds. The apparatus allows the user to connect various independently controlling and conveying means to each reaction vessel through multiple ports provided on a stopper mounted on each reaction vessel. The apparatus of the present invention permits user to readily access the reaction vessels without interrupting the reactions occurring in the adjacent reaction vessels. The unique geometry and shape of the stopper allows positioning of multiple ports, while still providing the stopper with a compact size. As a result, a large array of reaction vessels can be accommodated in the device of the present invention without significantly increasing the overall size of the apparatus. Some of the general compounds that can be readily synthesized by the apparatus and the method of the present invention include inorganic compounds as well as organic compounds, such as oligomers, polymers, agricultural chemicals, drugs, peptides and oligonucleotides.

摘要:Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of type (I) are constituted by three distinct building blocks: an aromatic template a, a conformation modulator b and a spacer moiety c as detailed in the description and the claims. Macrocycles of type (I) are readily manufactured by parallel synthesis or combinatorial chemistry. They are designed to interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT 2B (5-HT 2B receptor), and on the prostaglandin F2•receptor (FP receptor). They are thus potentially useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; of CNS related diseases like migraine, schizophrenia, psychosis or depression; of ocular hypertension such as associated with glaucoma and preterm labour.
