應用

Selenourea [(SeC(NH22)]已用作硒(Se)的前体,用于将Se插入蛋白质晶体中。
它也可作为试剂用于:
  • 从α-溴代酮合成硒唑(在β-环糊精存在下)。
  • 在氧化铜纳米颗粒作为催化剂的条件下,通过C-Se交叉偶联反应合成对称的二芳基硒化物。
  • 合成CdSe纳米晶体。

We report a general strategy for obtaining high-quality, large-area metal-chalcogenide semiconductor films from precursors combining chelated metal salts with chalcoureas or chalcoamides. Using conventional organic solvents, such precursors enable the expeditious formation of chalco-gels, which are easily transformed into the

The direct lattice strain, either distortion, compressive, or tensile, can efficiently alter the intrinsic electrocatalytic property of the catalysts. In this work, we report a novel and effective strategy to distort the lattice structure by constructing a metastable MoSSe solid

This study investigated inhibitory effects of N,N-unsubstituted selenourea derivatives on tyrosinase activity. Three types of N,N-unsubstituted selenoureas derivatives exhibited inhibitory effect on dopa (3,4-dihydroxyphenylalanine) oxidase activity of mushroom tyrosinase. Compound D at a concentration of 200 microM exhibited 55.5% of
