“…Dynorphin A (1-13) (C 75 H 126 N 24 O 15 , mw/1604) 13 , which had a bio-polypeptide containing 13 amino acids, had analgesic effect and played a significant role in regulating the cardiovascular and respiratory systems. Drug loading on the support Magnetic Fe-containing mesoporous carbons with high surface areas and pore volume were synthesized through a simple soft-template route, wherein phenolic resin was used as a carbon precursor, triblock copolymer F127 as a template agent, tetraethyl orthosilicate as a silica precursor and hydrated iron nitrite as an iron source.…”
