Magnetic Ganoderma Lucidum Spores(mGLS):A Novel Regulatable Targeted Drug Delivery System

摘要

In the past decades,many materials have been studied as carriers for targeted drug delivery.However,there is a need for utilizable and selective carrier materials with few side effects.Here,the magnetic Ganoderma Lucidum Spores(mGLS)as a highly efficient targeted drug delivery carrier were explored.Then the regulatable targeted drug delivery system was verified by loading and releasing of the 5-Fluorouracil(5-FU).The results showed that the maximum of the loaded 5-FU reached 250.23 mg·g^(−1)in the mGLS.The cumulative release of the 5-FU for the drug delivery system could reach 80.11%and 67.14%in the PBS and HCl after 48 h,respectively.In addition,this system showed the good pharmacokinetic properties in vivo.After 12 h,the blood concentration in the 5-FU@mGLS group kept at 5.3µg·mL^(−1)and was four times higher than that in the 5-FU group.In summary,the GLS as a natural microscale core-shell structures appears the striking application in carrier material for oral drug delivery.
