Abstract: POZ-lipid conjugates and lipid nanoparticles (LNPs) including POZ-lipid conjugates used to facilitate delivery of an encapsulated payload. LNPs including POZ-lipid conjugates and a nucleic acid payload such as, but not limited to, mRNA or modified mRNA are disclosed. Such LNPs have no immunogenicity or reduced immunogenicity as compared to a corresponding LNP containing a PEG-lipid.

Abstract: The present invention provides a scalable synthesis of enantiomerically pure brivaracetam, and related derivatives.

Abstract: A method for preparing a water-soluble curcumin liquid includes the following steps: A) dissolving curcumin, vitamin C and ascorbyl palmitate in an ethanol aqueous solution, evaporating ethanol under reduced pressure, and vacuum drying to obtain a curcumin-vitamin C-ascorbyl palmitate co-crystal; and B) high-speed emulsifying the curcumin-vitamin C-ascorbyl palmitate co-crystal and a water-soluble colloidal solution that includes an emulsifying additive under vacuum, sequentially conducting a two-stage wet grinding, a homogenization and a potential adjustment to obtain the water-soluble curcumin liquid.
