Application

Manganese(II) chloride tetrahydrate may be used to accelerate the synthesis of dihydropyrimidin-2(1H)-ones by the condensation of aldehyde, β-dicarbonyl compounds and urea under microwave conditions. It may also be used in the synthesis of manganese(II) tris(2-benzimidazolylmethyl)amine (ntb) complexes.

Nanoparticles of a new three-dimensional Mn(II) coordination supramolecular compound, [Mn(L)2(H2O)2] (1), (L(-)=1H-1,2,4-triazole-3-carboxylate), have been synthesized by a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. Structural determination of compound 1

A series of manganese(II) tris(2-benzimidazolylmethyl)amine (ntb) complexes were synthesized and characterized. In these complexes, ntb functions as a tripodal tetradentate ligand, resulting in trigonal pyramidal geometry. The complexes have five- to seven-coordinate manganese(II) ions depending on the additional ligand used.

We describe a method for the efficient and selective identification of DNA containing the 5-hydroxymethylcytosine (5-hmC) modification. This protocol takes advantage of two proteins: T4 β-glucosyltransferase (β-gt), which converts 5-hmC to β-glucosyl-5-hmC (β-glu-5-hmC), and J-binding protein 1 (JBP1), which specifically
