摘要:Compositions, methods and kits for in vitro systems for synthesis of biomolecules such as polypeptides, are provided herein. Cell extracts that provide enhanced yields of soluble proteins using in vitro protein synthesis methods are provided. The invention also includes methods for producing high yields of proteins by the addition of a feeding solution that includes amino acids and an energy source to an ongoing in vitro synthesis system. The invention also includes methods of using a high-yield in vitro synthesis system to produce large quantities of proteins with incorporated labeled amino acids for analysis by methods such as by NMR. The invention further includes vectors for enhanced production of proteins from nucleic acid templates using in vitro synthesis systems.

标 题:Synthesis of furyl intermediates, and cardenolides and their isomers prepared therefrom
发明人：WIESNER KAREL; TSAI THOMAS Y R
权利人:ADVANCE BIOFACTURES CORP
摘要:The invention relates to furyl intermediates and the preparation thereof, said intermediates being particularly useful in the preparation of synthetic cardenolides and their isomers. The process provides for the reaction of an unsaturated steroidal 17 ketone with a β-furyl compound to produce an allylic alcohol which is subjected to acetylation and allylic rearrangement. The resulting material is then hydrogenated to produce the furyl intermediate. Cardenolides are formed therefrom by oxidation of the furyl intermediates.
