Polysulfonated macromolecules are known to bind selectins, adhesion membrane proteins which are broadly implicated in inflammation. Commercially available branched polyethylenimine (PEI) was reacted with chlorosulfonic acid to generate sulfonated PEI with varying degrees of sulfonation. Remaining unreacted amine groups were then used for straightforward conjugation with pyropheophoribide-a, a n...
Heparin-based anticoagulants are drugs of choice in the therapy and prophylaxis of thromboembolic diseases. Idraparinux is a synthetic anticoagulant pentasaccharide based on the heparin antithrombin-binding domain. In the frame of our ongoing research aimed at the synthesis of sulfonic acid-containing heparinoid anticoagulants, we elaborated a modular pathway to obtain a series of idraparinux-a...
In this study, a solid acid was prepared by the sulfonation of surface modified α-zirconium phosphate (ZrP) single-layer nanosheets (SO3H@ZrP), and the prepared solid acid was investigated for the esterification of oleic acid with methanol to produce biodiesel. For comparison, liquid H2SO4 and commercial Amberlyst® 15 catalyst were also evaluated for the same reaction under the same conditions....
