Spectrophotometric Determination of 4-Hydroxy-2-mercapto-6-methylpyrimidine Based on Aggregation of Colloidal Gold Nanoparticles
We report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (MTU) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (Au-NPs). This thiol-containing molecule exhibits intriguing affinity with Au-NPs. The reactivity involves the displacement of the citrate shell by the thiolate shell followed ...

interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
متن کاملSynthesis and Biological Evaluation of 4-hydroxychromenyl arylmethyl-6-hydroxy pyrimidine-2, 4-dione Derivatives
Background: An efficient, promoted tri-component catalytic reaction between barbituric acid (or N,N-dimethyl barbituric acid), 4-hydroxy coumarin, and a wide range of aryl aldehydes using zinc oxide nanowires (ZnO NWs) to obtain some new 4-hydroxychromenylarylmethyl-6-hydroxypyrimidine-2,4-diones is described. Method: The reactants were successfully condensed ...
متن کاملSolid–Solid Synthesis, Crystal Structure and Thermal Decomposition of Copper(II) Complex of 2-Picolinic Acid
The copper(II) complex [Cu(pic)2]·2H2O was synthesized with 2-picolinic acid (Hpic) and copper acetate as reactants by room temperature solid-solid reaction. The composition and structure of the complex was characterized by elemental analyses, single crystal X-ray diffraction, X-ray powder diffraction, FT-IR spectroscopy and thermogravimetry-differential scanning calor...
