  • Publication number: 20220218651
    Abstract: The present disclosure relates to the preparation of a highly pure cannabidiol compound by a novel synthesis route. The cannabidiol compound can be prepared by an acid-catalyzed reaction of a di-halo olivetol with menthadienol, followed by two crystallization steps. The highly pure cannabidiol compound is produced in high yield, stereospecificity, or both, and shows exceedingly low levels of ?-9-tetrahydrocannabinol at the time of preparation and after storage.

  • Publication number: 20150094267
    Abstract: The present invention relates to succinimide-activated nitroxyl compounds and methods for the synthesis of such compounds. The present invention also relates to the use of succinimide-activated nitroxyl compounds to prepare nitroxylated proteins, for example nitroxylated heme proteins (e.g., nitroxylated hemoglobin and nitroxylated myoglobin). The nitroxylated proteins are optionally also conjugated to a polyalkylene oxide (PAO), for example to a polyethylene glycol (PEG). Polynitroxylated heme proteins are useful as oxygen therapeutic agents (OTAs). The invention further relates to pharmaceutical compositions of the nitroxylated proteins and methods for the use of nitroxylated proteins in the treatment of various conditions.
