The process of complexation molybdenum (V) with 1-phenyl-2,3-dimethylpyrazolin-5-thione in a 4 mol/l HCI medium the temperature range 273-338 K was studied by potentiometric method. It has been shown that reduced form molecule is involved complex formation reaction. Using data studies, change energy value (ΔE) (NH ) 2 [MoOCI 5 ] -1-phenyl-2,3-dimethylpyrazolin-5-thione-4 HCl system, equilibrium...

The title multifunctional twisted organic ligand, C(10)H(10)N(4)S(2), contains a short C=S bond [1.671 (2) Å]. The dihedral angle between the two pyrazine rings is 39.83 (6)°. In the crystal, inter-molecular C-H⋯N and C-H⋯S hydrogen bonds result in the formation of a supra-molecular network.

Based on the hits, 3,4-dihydroquinazoline-2-thione (1) and benzimidazole-2-thione (2), a series of indole-2-thione (3) and indole-2-thiol inhibitors (4) of melanogenesis were designed, synthesized and evaluated in melanoma B16 cells under the stimulant of α-melanocyte stimulating hormone (α-MSH). The indole-2-thione compounds (3a-g) exhibited an effective inhibitory activity on melanin synthesi...

The title compound, C19H23N3S, is a functionalized triazoline-3-thione derivative. The benzyl ring is almost normal to the planar 1,2,4-triazole ring (r.m.s. deviation = 0.007 Å) with a dihedral angle of 86.90 (7)°. In the crystal, molecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers that enclose R 2 (2)(8) loops. The crystal packing is further stabilized by weak C-H⋯...
