摘要:In the synthesis of ascofranone, a compound represented by formula (III), (IV), (V) or (VII) or an optical isomer thereof is used as an intermediate for the synthesis. [In the formulae, R 1 and R 2 independently represent a hydrogen atom, a C 1-7 alkyl group, a phenoxyalkyl group having a halogen atom on a carbon atom in a benzene ring therein, or a phenyl group having a C 1-7 alkoxy group or a C 1-7 alkoxycarbonyl group on a carbon atom in a benzene ring therein; and X represents a halogen atom or a group R 5 SO 3 (wherein R 5 represents a C 1-7 alkyl group or a phenyl group having a C 1-7 alkyl group on a carbon atom in a benzene ring therein).] By using the compound, it becomes possible to reduce the number of steps required for the total synthesis of ascofranone to 7 or 8 from 12 which is a number of the steps required for the conventional ascofranone total synthesis processes.

摘要:The invention is directed to isopsoralen compound compositions that contain a variety of substitutions which yet permit their binding to nucleic acid polymers. Reaction conditions that activate these bound isopsoralens results in covalent crosslinking to the nucleic acid polymers. The resultant complex is inhibited from being a template for the template-directed enzymatic synthesis of a complementary nucleic acid polymer. Beside the isopsoralens compositions, the invention includes their synthesis, the nucleic acid complex production and detection, and the above inhibitory method of use of the isopsoralens.

标题 :Synthesis of rotavirus receptor saccharides

摘要:Saccharides which are active as rotavirus receptor sites are disclosed. These saccharides are synthetically produced sugar derivatives recognized by the antireceptor of a rotavirus. The molecules are useful in studying the interaction between the rotavirus antireceptor and most receptor sites so as to develop drugs useful in blocking the connection between such viruses and the host cells. Further, the molecules can be modified in order to increase the degree to which they attract the antireceptor sites of the virus and/or modified by binding to them antiviral compounds which are effective in destroying the virus once the receptor molecule binds to the virus. Synthetic receptor molecules recognizable by a rotavirus are obtainable by the synthesis methods disclosed.
