Two novel Zn(II)-Li(I)-based and In(III)-based coordination polymers: crystal structures and anti-lung cancer activity

Abstract

Abstract In this study, two new metal-organic frameworks, namely, {(H2NMe2)[Zn3LiO(BTA)2](DMF)3}n (1, H3BTA=3,3′,3″-[1,3,5-benzenetriyltris(carbonylimino)] trisbenzoic acid) and {(Me2NH2)2[In2(TTA)2(FBA)2](DMF)3}n (2, H3TTA=4,4′-(((5-((4-(hydroxy-l2-methoxy)phenoxy) methyl)-2,4,6-trimethyl-1,3-phenylene)bis(methylene))bis(oxy))dibenzoic acid, HFBA=2-fluorobenzoic acid), were obtained via a one-pot solvothermal reaction of metal salts and organic connectors. The structures of the title two metal-organic coordination compounds were structurally probed via X-ray single crystal diffraction technique. In connection to their structures, the MTT assay was used to access the in vitro antitumor activities for compounds 1 and 2 against the human lung cancer cells (MSTO-211H, NCI-H1299 and NCI-H292).
