Abstract
Abnormal melanin overproduction can result in hyperpigmentation syndrome in human skin diseases and enzymatic browning of fruits and vegetables. Recently, our group found that Keggin-type polyoxometalates (POMs) can efficiently inhibit tyrosinase activity. However, it remains unclear whether Keggin-type POMs exhibit optimal effects in vivo. Additionally, the inhibitory effect and mechanism of action of POMs on cellular tyrosinase activity and melanogenesis have been rarely reported. Here we demonstrate that our screened and synthesised PMo11Zn and GaMo12 show superior inhibitory effects on melanin formation as well as inhibition of cellular tyrosinase activity compared to other Keggin-type POMs. Intriguingly, we reveal that Keggin-type POMs competitively bind to tyrosinase mainly through more interactions with Cu2+ ions and the amino acid residue is capable of forming van der Waals, cation-π and hydrogen bonds, resulting in a reversible non-covalent complex formation. Our findings provide valuable insights into the design, synthesis and screening of polyoxometalates as multifunctional metallodrugs and food preservatives against hyperpigmentation.

Abstract
We report an efficient and economical amidation strategy by using a polyoxometalate-based iron catalyst that affords the corresponding amide products in good yields. All of the aliphatic, aromatic and heterocyclic substrates are produced in high yields without additional base or organic ligands. Most importantly, the first example of heterogeneous iron(III)-catalyzed formation of the diamides is developed.

Abstract
Four new transition metal-containing Nb/W mixed-addendum POM trimers with the formula H19[M4(H2O)x(P2W15Nb3O62)3]·m(HCOOH)·nH2O (M = Cu, x = 15, m = 0, and n = 21, Cu-POM; M = Co, x = 7, m = 0, and n = 15, Co-POM; M = Mn, x = 7, m = 6, and n = 18, Mn-POM; and M = Zn, x = 7, m = 0, and n = 23, Zn-POM) have been synthesized by a solvothermal method in a water-ethanol mixed solvent. All the four compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction (XRD), IR spectroscopy, thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). These compounds can serve as efficient heterogeneous catalysts for the cyanosilylation of different carbonyl compounds under ambient temperature and solvent-free conditions, and Cu-POM shows much better catalytic performance than the other three compounds. The cycle experiment showed that Cu-POM can be reused for at least five cycles without significant loss of catalytic activity. The IR spectroscopy and XRD analysis revealed that Cu-POM can retain its integrity after catalysis.
