Micro/nano materials, products obtained by covalently modifying surface of micro/nano materials with hydrophilic materials, and method for making same

Micro-nano materials, products obtained by covalently modifying the surfaces of micro/nano materials with hydrophilic materials, and methods for making the same. The micro/nano materials on the surfaces have carboxyl groups or/and pro-carboxyl groups which are converted into their active esters. The products are covalently modified by forming amide bonds between the active esters on the surfaces and the modification agents; where the modification agents are hydrophilic compounds and/or hydrophilic polymers bearing primary and/or secondary aliphatic amines. Monomers bearing carboxyl groups and/or pro-carboxyl groups are used to produce an adequate number of carboxyl groups and/or pro-carboxyl groups on the surface of a polymer material to be modified. The carboxyl groups and/or pro-carboxyl groups are converted into active esters. A reasonably-sized modification agent bearing primary and/or secondary amines, zwitterions and hydrophilic linear spacer arms is used to form amide bonds and obtain a covalently modified surface layer.

ANAPLEROTIC AGENTS FOR TREATMENT OF DISORDERS OF PROPIONATE AND LONG CHAIN FAT METABOLISM

Methods of treating propionic acidemia (PA), methylmalonic acidemia (MMA) and fatty acid oxidation disorders are described. The methods include administering an anaplerotic agent that can directly enter the tricarboxylic acid cycle, such as a succinate derivative or pro-drug, for example trisuccinylglycerol (TSG). Methods of restoring tricarboxylic acid (TCA) cycle function in a cell deficient for propionyl-CoA carboxylase (PCC) or methylmalonyl-CoA mutase (MUT) by contacting the cell with a succinate derivative or pro-drug, such as TSG, are also described.
