Abstract: Porous metal-organic frameworks(MOF-5) were synthesized and the structure of synthetic MOF-5 was confirmed by XRD and IR spectrum. According to the result of TG, the synthetic MOF-5 displayed better thermo-stabilization. The capsaicin or 5-fluouourail was loaded in synthetic MOF-5 and in vitro drug release profile were investigated, respectively. The highest drug loading rates are 0.592 g/g MOF for capsaicin and 0.315 g/g MOF for 5-FU in drug-loaded MOF-5, respectively. The in vitro drug release profile of both MOF-5 formulations showed a clear biphasic release pattern. Cytotoxicity test showed that MOF-5 displayed good biocompatility.

Key words: Metal-organic framework(MOF), Capsaicin, 5-Fluouourail(5-FU), Drug loading rate, Drug sustained release, Cytotoxicity
