Compounds and compositions that have a mannose 6-phosphate receptor or ASGPR binding ligand bound to an extracellular protein binding ligand are provided for the selective degradation of a target extracellular protein in vivo to treat disorders mediated by the extracellular protein.

Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids, such as galactaric acid, under neutral or acidic conditions. Use is made of a supported gold catalyst. The oxidation occurs in good selectivity and yield, under unexpectedly mild conditions. A source of galacturonic acids is pectins, such as from sugar beet pulp.

Novel delivery nanoparticles composes of two-, or three-component lipid compounds. Compositions comprising such lipid compounds, and related methods of their use are disclosed. Nanoparticle compositions include at least one novel modular lipid as well as additional lipids such as ionizable lipids, and phospholipids. Nanoparticle compositions further including biologically active agents, such as siRNA or mRNA, are useful in the delivery of said biologically active agents to subjects in need thereof.

An oxidized -1,4-oligoglucuronic acid, and a preparation method therefor and uses thereof. By using abundant starch, especially soluble starch, in the natural world as the raw material, all 6-site hydroxyl groups of the starch -1,4-polyglucose are oxidized into carboxyl groups to form glucuronic acid under the action of a sodium bromide (NaBr)-2,2,6,6-tetramethyl piperidine oxide (TEMPO)-sodium hypochlorite (NaClO) oxidation system, and the oxidized oligoglucuronic acid having an open ring at an end is prepared by controlling reaction conditions. The compound has obvious anti-cerebral ischemia activity, and can be developed into a potential anti-cerebral ischemia drug.
