权利人:UNITED THERAPEUTIC CORP
摘要:An improved method is described for making 9-deoxy-PGF 1 -type compounds. In contrast to the prior art, the method is stereoselective and requires fewer steps than the known methods for making these compounds. The invention also relates to novel intermediates prepared during the synthesis of the 9-deoxy-PGF 1 -type compounds.

摘要:The present invention is directed to a method for continuous production of dihydroartemisinin and also artemisinin derivatives derived from dihydroartemisinin by using artemisinin or dihydroartemisinic acid (DHAA) as starting material as well as to a continuous flow reactor for producing dihydroartemisinin as well as the artemisinin derivatives. It was found that the reduction of artemisinin to dihydroartemisinin in a continuous process requires a special kind of reactor and a special combination of reagents comprising a hydride reducing agent, at least one activator such as an inorganic activator, at least one solid base, at least one aprotic solvent and at least one C 1 -C 5 alcohol.

摘要:Embodiments of the synthesis, radiolabeling and biological applications of an activatable tracer that undergoes intramolecular cyclization and aggregation upon activation by cleavage of a blocking moiety are provided. The probes of the disclosure allow for target-controlled self-assembly of small molecules in living subjects for imaging and drug delivery. The aggregated nanoprobes of the disclosure may be detectable optically, by PET detection, magnetic resonance imaging, and the like depending on the detectable reporter attached to the nanoprobe.
