A Non-innocent Magnesium Organoclay-Based Drug Vehicle for Improving the Cancer Therapy Effect of Methotrexate

A synthetic, dispersible magnesium aminoclay (MgAC) was synthesized in the present study. Besides, structural and spectroscopic detections were conducted to investigate the MgAC nanoclay. With a poor aqueous solubility, methotrexate (MTX) has been applied as a valid antitumor agent in recent years. In our research, an unobtrusive sol-gel process was carried out to manufacture the MgAC-MTX nanohybrids through entrapment of MTX over MgAC in situ . The final product was capable of desquamating and thus dispersed in water, equably. In comparison with rough MTX, the MgAC-MTX nanocomposite with a preferable treatment efficacy against MCF-7 cells was mainly attributed to the preeminent enhanced aqueous solubility, controlled release and the increased cellular uptake capacity. Moreover, with excellent anticancer function and hypotoxicity as vindicated in vivo , the MgAC-MTX nanohybrid was supposed to own the potency in the application of malignant tumors cure as a valid nanomedicine. It turned out that, by virtue of its high bioavailability, the MgAC-MTX nanohybrids with high bioavailability is deserving of further study for the treatment of cancers.
