In the title compound, C(14)H(14)BrN(5)O(3), the mean plane of the imidazole ring (r.m.s deviation = 0.004 Å) forms a dihedral angle of 58.13 (7)° with the benzene ring. In the crystal, mol-ecules are linked via N-H⋯O, C-H⋯O and C-H⋯N hydrogen bonds into a three-dimensional network. A short Br⋯Br contact of 3.4932 (2) Å also occurs.
A series of N-[3-{(1H-benzo[d]imidazol-2-ylthio) methyl}-5-mercapto-4H-1, 2, 4-triazol-4yl]-2-substituted phenoxy acetamide 6(a-g) were synthesized by the mixture of the compound of potassium 2-(2-(1H-benzo[d]imidazol-2-ylthio) acetyl) hydrazinecarbodithioate (4) and aryloxy acid hydrazide (5) in presence of hydrochloric acid. The predicted structures of the synthesized compounds were confirmed...
In the title inner salt molecule, C10H10N2O3, the four-membered cyclobutene ring is twisted by 7.1 (2)° with respect to the five-membered imidazole ring. The crystal packing exhibits an R 2 (2)(9) hydrogen-bonding ring motif through N-H⋯O and C-H⋯O inter-actions. The potential non-linear optical properties were studied by a computational ab initio calculations performed at the DFT/B3LYP/6-31++G...
Herein we describe the synthesis and in vitro biological evaluation of thirteen new, racemic, diversely functionalized imidazo pyranotacrines as non-hepatotoxic, multipotent tacrine analogues. Among these compounds, 1-(5-amino-2-methyl-4-(1-methyl-1H-imidazol-2-yl)-6,7,8,9-tetrahydro-4H-pyrano[2,3-b]quinolin-3-yl)ethan-1-one (4) is non-hepatotoxic (cell viability assay on HepG2 cells), a select...
