  • Patent number: 11944686
    Abstract: Disclosed are conjugate molecules formed from an active agent which is linked to a cannabinoid moiety through a specified linker having ester and amide end groups. The active agent can be a COX-2 inhibitor moiety, and the cannabinoid moiety can be a cannabidiol moiety. These conjugate molecules are contemplated to potentially be effective in the treatment of medical conditions.
    Type: Grant

  • Publication number: 20200002261
    Abstract: The present invention provides processes for preparing a prostacyclin analogue of Formula I or a pharmaceutically acceptable salt thereof, wherein R10 is a linear or branched C1-6 alkyl. The processes of the present invention comprise steps that generate improved yields and fewer byproducts than traditional methods. The processes of the present invention employ reagents (e.g., the oxidizing reagent) that are less toxic that those used in the traditional methods (e.g., oxalyl chloride). Many of the processes of the present invention generate intermediates with improved e.e. and chemical purity; thereby eliminating the need of additional chromatography steps. And, the processes of the present invention are scalable to generate commercial quantities of the final compound.
