ABSTRACT
γ-Cyclodextrin metal-organic frameworks (CD-MOFs) are considered as a green and biocompatible material with great potential in drug delivery systems. Original CD-MOFs show the poor aerosol properties, which limit the application in pulmonary drug delivery. To improve the in vitro deposition properties, herein, we synthesized CD-MOFs by the vapor diffusion method using a series of modulators to achieve better pulmonary delivery of cyclosporine A (CsA). The results showed that blank CD-MOFs and drug loaded CD-MOFs prepared with different modulators all preserved the cubical shape, and exhibited the similar crystal form, structural characteristics, thermal behaviors and release properties. In addition, drug loaded CD-MOFs prepared with polyethylene glycol 10000 (PEG 10000) as a modulator exhibited better in vitro aerosol performance than those of synthesized using other modulators, and the in vivo pharmacokinetics data demonstrated that the bioavailability of CsA could be significantly enhanced by inhalation administration of drug loaded CD-MOFs compared with oral administration of Neoral®. The repeated dose inhalation toxicity also confirmed the fine biocompatibility of CD-MOFs as the carrier for pulmonary drug delivery. Therefore, the results demonstrated CD-MOFs as the promising carrier could be used for pulmonary drug delivery.
