Abstract
Herein, a biocompatible 2D metal-organic frameworks (Cu-TCPP(Fe)) based on TCPP(M) (TCPP = tetrakis (4-carboxyphenyl) porphyrin, M = Fe) and copper ion were synthesized as a novel drug carrier. Sequentially, the cisplatin was loaded on the merge of carboxyl-rich Cu-TCPP(Fe) through forming favorable carboxyl-drug interactions. The prepared Pt/Cu-TCPP(Fe) showed highly enhanced cytotoxicity than that of free cisplatin in human pulmonary carcinoma A549 cells, whereas inverse inhibitory effects were observed in human normal BEAS-2B cells. Further, the mechanism of action about the desirable results was also elaborated. Our study highlighted the potential synergies between the nanocarrier and the anticancer drugs.
