Abstract:
We reported the design and synthesis of mixed ligands Cu-metal organic frameworks (MOFs), MOFs-2 and MOFs-3, and their application as the transport vehicles for the delivery of Ibuprofen (IBU) and doxorubicin hydrochloride (DOX). The unique MOFs with mixed ligands, 1,3,5-benzene tricarboxylate (BTC) and isophthalic acid (IPA), were easily prepared by hydro-thermal method, and their structures were well characterized by XRD, FTIR, and SEM imaging analysis. Single ligand MOFs with BTC or IPA only were also prepared and characterized as the control group. The biocompatibility of synthesized MOFs towards human cells, HEK 293A was evaluated by MTT assay. To demonstrate the practical applications of the prepared MOFs as the transport vehicles for drugs, the capability of loading and controlled release of IBU and DOX by MOFs-1, MOFs-2, MOFs-3, and MOFs-4 were then examined. In addition, the drug delivery efficiency of various MOFs with different ligands was investigated.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
