Unfortunately, serious clinical side effects are associated with it, which are caused by PTX itself and non-aqueous vehicle containing Cremophor EL. Development of new formulation of PTX with better efficacy and fewer side effects is(More)
YSL was prepared stepwise from C terminal to N terminal with the side chain un-protective amino acids, Boc-Leu-OMe, Boc-Ser-OH, and Boc-Tyr-OH, as the starting materials in 39.5% total yield (31.2g/per batch). With the side chain un-protective Boc-(3,5-dibromo)-Tyr-OH and HCl.Ser-Leu-OMe as the starting materials (3,5-(3)H-Tyr)-Ser-Leu-OH was obtained in(More)
An amphiphilic chitosan derivate, N-octyl-O-sulfate chitosan (NOSC) was prepared by octylation of amino group at C-2 position and sulfonylation at C-6 position. Micelle formed by NOSC has great capability in solubilization of water-insoluble drug paclitaxel. Enormous attention was attracted by the potential application of NOSC as a new drug delivery system.(More)
