Cation-Exchangeable Pralidoxime Chloride@bio-MOF-1 as a Treatment for Nerve Agent Poisoning and Sulfur Mustard Skin Poisoning in Animals. ACS OMEGA 2022; 7:30720-30729.

Abstract
A 2-PAM@bio-MOF-1 composite was prepared by cationic exchange of counter N,N-dimethylammonium cations in the pores of the anionic, biocompatible metal-organic framework (bio-MOF-1) with pralidoxime chloride (2-PAM-Cl) by impregnation. In vitro drug release measurements revealed that the release rate of 2-PAM from 2-PAM@bio-MOF-1 in simulated body fluid (SBF) was more than four-fold higher than that in deionized water, indicating that the presence of endogenous cations in SBF triggered the release of 2-PAM through cation exchange. The release of 2-PAM was rapid within the first 10 h but was much slower over the period of 10-50 h. At room temperature, the maximum release rate of 2-PAM was 88.5% (15 mg of 2-PAM@bio-MOF-1 in 1 mL of SBF), indicating that the drug was efficiently released from the composite MOF in SBF. In simulated gastric fluid, 64.3% of 2-PAM was released from bio-MOF-1 into the simulated gastric fluid after 50h. This suggested that 2-PAM@bio-MOF-1 might be effective for enabling the slow release of 2-PAM in the human body. Indeed, the maximum reactivation rate of acetylcholinesterase in sarin-poisoned mice reached 82.5%. In addition, 2-PAM@bio-MOF-1 demonstrated the ability to adsorb and remove sulfur mustard (HD) in solution and from the skin of guinea pigs.

Abstract
Driven by the synergistic-directing effect of the lacunary fragments, [B-α-GeW9O34]10- and [B-α-GeW11O39]8-, an unprecedented hepta-Zr-substituted polyoxometalate (POM) assembly K2Na6H10(Hpy)3[SbZr7O6(OH)4(B-α-GeW9O34)2(B-α-GeW11O39)2]·28H2O (1) was made under hydrothermal condition and structurally characterized. Of which, a unique hepta-Zr cluster, [SbZr7O6(OH)4]15+ core, was built by two trilacunary [B-α-GeW9O34]10- fragments and two monolacunary [B-α-GeW11O39]8- fragments and further arranged in a mode of a vertical cross and formed a pseudo-tetrahedron geometry. Compound 1 features the first Zr7-cluster-substituted POM. Moreover, 1 is an effective heterogeneous catalyst for the catalytic oxidation of sulfides into the corresponding sulfones with H2O2, manifesting distinguished conversion, excellent yield, and desired recyclability.
