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.

摘要:The present disclosure provides a method of preparing certain 3,4-dihydro-4-aryl coumarin derivatives. Cinnamic acid, or a certain derivative thereof, may react with phenol, or a certain derivative thereof (e.g., resorcinol), with removal of water azeotropically in the presence of a catalyst and an organic solvent to form a certain 3,4-dihydro-4-aryl coumarin derivative. The present disclosure also provides certain novel 3,4-dihydro-4-aryl coumarin derivatives, and compositions, kits, and methods of use thereof.

权利人:VIRGINIA TECH INTELL PROP
摘要:Novel bis(extraannular functionally-substituted phenylene) crown compounds, useful as chelating agents or in the synthesis of condensation polymers containing large semi-rigid macrocycles in the polymer backbone, are described. A broad range of functional groups (preferably in the 5-position) can be used in the 1,3-phenylene varieties. Carboxy functional groups are used in certain novel 1,2-phenylene crowns.
