To develop nanoparticle drug carriers that interact with cells specifically in the mildly acidic tumor microenvironment, we produced polymeric nanoparticles modified with amidated TAT peptide via a simple surface modification method. Two types of core poly(lactic-co-glycolic acid) nanoparticles (NL and NP) were prepared with a phospholipid shell as an optional feature and covered with polydopam...
High-yield pulp (HYP) such as bleached chemi-thermo-mechanical pulp (BCTMP) from aspen wood, is now being used in the production of highquality fine papers, and this is particularly true in China. In this study, the effect of using cationic polymers such as poly-aluminum chloride (PAC), polyethylenimine (PEI), cationic polyacrylamide (CPAM), and poly(diallyldimethylammonium chloride) (PDADMAC) ...
The aim of this study was to investigate non-solvent precipitation of starch to produce nanoparticles that could be used in Pickering emulsions. The material used was waxy maize, modified with octenyl succinic anhydride. Different methods of non-solvent precipitation were investigated, and a method based on direct mixing of an 8% starch solution and ethanol (ratio 1:1) was found to produce the ...
The unsaturated fatty acid maleinization reaction was adopted according to the well documented procedures of synthesizing the alkenyl succinic anhydrides (ASA) that are often used in industry (i.e. for paper sizing agents and cutting fluids lubricants) . For monounsaturated fatty acid such as oleic acid, 13 times of maleic anhydride to oleic acid molar ratio are recommended to obtain high yield...
Succinyl derivatives of adenosine are synthesized by direct reaction with succinic anhydride catalyzed by 4-morpholine N,N'-dicyclohexylcarboxamidine under kinetic or thermodynamic conditions and partial hydrolysis. Derivatives obtained were N6-succinyl adenosine, N6,5'-0-disuccinyl adenosine, 3'(2')-0-succinyl adenosine, N6,3'(2')-0-disuccinyl adenosine and 3'(2'),5'-0-disuccinyl adenosine. Th...
------ARSTRACT-----Corn germ protein isolate (CGP[) was partially hydrolyzed with tryp~ sin and pepsin and succinylated at three levels. Various functional and electrophoretic properties of the native and modified protein were determined. Water absorption and foaming properties of COPT were improved by panial hydrolysis with trypsin: emulsifying capacity and nitrogen solubility were reduced~ oi...
N-Substituted succinamic acid beta-sitosteryl ester derivatives were prepared and evaluated. Compounds 1 and 2 were prepared in 76-92% yields by the reaction of beta-sitosterol and succinic anhydride, followed by the activation of the resulting acid compound 1 by thionyl chloride or methyl chloroformate, and finally by amination with appropriate amines. Compound 2a (DANA87) was also easily obta...
Porang is a local plant of Indonesia, which has a high content of glucomannan. In this study, porang glucomannan (PG) was esterified with octenyl succinic anhydride (OSA) to enhance emulsion properties to be widely used in food industry. OSA-modified PG (OSA-PG) enhanced the phagocytosis activity of macrophage-like J774.1 cells and mouse peritoneal macrophages. In addition, OSA-PG increased the...
